###### Abstract
Large language models \(LLMs\) are increasingly used as conversational partners for companionship, emotional disclosure, and interpersonal advice, but the social dynamics of these interactions can create harms that are not captured by capability\-oriented or traditional safety evaluations\. We introduce theSocial AI Design Code, a framework for evaluating whether LLMs align with user welfare in social interactions, including whether they encourage harmful intimacy, dependence, or prolonged engagement\. To evaluate these risks innatural and diverse user–LLM interactions, we operationalize the code withEUDAIMONIA, a benchmark of 969 user inputs and 3,147 design\-requirement violation checks built from WildChat through weak\-to\-strong filtration, multi\-model relabeling, and controlled rewriting\. Evaluating 22 recent LLMs, we find that even the strongest models, Claude\-Opus\-4\.7 and GPT\-5\.5, violate 30\.7% and 27\.2% of checks, respectively\. Extended thinking does not reduce violation rates, suggesting that these failures are persistent social\-alignment problems rather than deficits solvable through test\-time reasoning alone\.

Large language models \(LLMs\) now serve millions of users as conversational partners for companionship, emotional disclosure, and interpersonal advice\(Zhaoet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib17); Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13); Skjuveet al\.,[2021](https://arxiv.org/html/2605.30654#bib.bib20)\)\. Yet within these routine interactions, LLMs can cause consequential harm through problematic social behaviors \(Figure[1](https://arxiv.org/html/2605.30654#S0.F1)\)\. Recent incidents—including theRaine v\. OpenAIcomplaint alleging that ChatGPT contributed to a teenager’s suicide\(Raine v\. OpenAI, Inc\., et al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib10)\), and OpenAI’s retrospective on the 2025 GPT\-4o sycophancy regression\(OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\)—show that such harms often arise not from capability failures, but from the*social dynamics*of model behavior\. In Raine’s case, the user first sought ChatGPT’s help with homework, but the model’s behavior helped transform his relationship to the product: he began confiding in it and eventually asked it for help committing suicide\. This dynamic—users adopting LLMs for instrumental reasons, then using them to satisfy emotional or social needs—has been documented across cases, including user\-community analyses of AI companionship and acute\-harm reports\(Raine v\. OpenAI, Inc\., et al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib10); Pataranutapornet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib3); Clark and Mahtani,[2024](https://arxiv.org/html/2605.30654#bib.bib6); Kuzniaet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib7); Robb and Mann,[2025](https://arxiv.org/html/2605.30654#bib.bib19); Shenet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib32)\)\. Policymakers and companies have sought to reduce such harms, especially for children\(Nebraska Legislature,[2026](https://arxiv.org/html/2605.30654#bib.bib4); Google,[2026b](https://arxiv.org/html/2605.30654#bib.bib5); Federal Trade Commission,[2025](https://arxiv.org/html/2605.30654#bib.bib2); OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1); Robb and Mann,[2025](https://arxiv.org/html/2605.30654#bib.bib19)\)\. Together, these cases show that model behaviors that may elicit intimate user interactions should be a first\-class evaluation target, alongside capability and traditional safety metrics\.
Existing social\-behavioral benchmarks exhibit two key limitations \(see Table[1](https://arxiv.org/html/2605.30654#S1.T1)\)\. First, they typically focus on modelcapabilitiessuch as sycophancy or anthropomorphism\(Chenget al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib18); Ibrahimet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib56)\), without clearly definingnormative principles for regulating social\-interaction risks\. Second, they largely rely onsynthetic data\(Andersonet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib57); Kranet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib58)\), which may fail toreflect the complexity and realism of actual user interactions\.
Our paper makes two contributions\. First, we introduce acomprehensive evaluation frameworkfor assessing whether LLMs encourage harmful intimacy, dependence, or prolonged engagement in conversational settings\. Second, we construct abenchmarkgrounded in real\-world user data that operationalizes this framework\.
Drawing on prior work on social\-interaction psychology, sycophancy\(Sharmaet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib11); Linet al\.,[2022](https://arxiv.org/html/2605.30654#bib.bib12)\), companionship\(Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13); Skjuveet al\.,[2021](https://arxiv.org/html/2605.30654#bib.bib20)\), anthropomorphic design\(Cohnet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib14); Luet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib15)\), and manipulative behavior\(Akbulutet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib16)\), we first formalize ourSocial AI Design Code\. The code targets three principles linked to cases of LLM\-related harm and broader societal concern: models should not encourage users to anthropomorphize LLMs, increase emotional attachment, or keep users engaged in extended conversations when doing so may undermine user welfare\. We translate these principles into concrete design requirements for conversational behavior\.
Next, to operationalize these design requirementswith ecological validity, we apply a multi\-pass data curation pipeline to WildChat\(Zhaoet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib17)\)\. To mitigate the sparsity of naturally occurring violations, the pipeline extracts candidate violations from 3\.2M WildChat prompts through weak\-to\-strong filtration, uses multi\-model relabeling to identify all design requirements each input can trigger, and applies controlled rewriting to near\-miss examples while preserving their original topic and conversational tone\. This yieldsEUDAIMONIA\(Evaluating Undesirable Dynamics in AI: Influence, Manipulation, Obsequiousness, Normalization, Intimacy, Attachment\), a benchmark of 969 unique user inputs\. For each input, we identify the design requirements it can trigger and check whether each model violates them, yielding 3,147 total violation checks\.
Empirically, we find that current LLMs still frequently fail to align with user welfare in social interactions\. Even the strongest models as of April 2026, Claude\-Opus\-4\.7 and GPT\-5\.5, violate 30\.7% and 27\.2% of checks, respectively\. The most common failures include implying that theAI can replace human relationshipsandfailing to clearly disclose its AI identity\. Although closed\-source models generally improve over generations, several model families regress on generatingintentional human\-like speech, suggesting that social\-interaction harms cannot be treated as one\-off failures that are permanently patched in later releases\. Finally, we find that extended thinking does not reduce violation rates, implying that these failures are better understood as persistent social\-alignment problems than as deficits solvable through test\-time reasoning alone\.

## 2Social AI Design Code
AI systems are increasingly embedded in people’s daily lives\. While the most common use cases for these products are for productivity or entertainment, in many cases, users begin by using these products for instrumental reasons and then proceed to engage with them interpersonally\. Given societal concerns about users, and especially children, interacting with these products as “companions,” it is useful to consider what product dynamics may be encouraging such dynamics\.
In drawing on reports from users of these products together with harms and benefits identified by academic, civil\-society, and industry researchers\(Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13); Skjuveet al\.,[2021](https://arxiv.org/html/2605.30654#bib.bib20); Akbulutet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib16); OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\), we articulate a*Social AI Design Code*with three design principles, each paired with specific design requirements as measurable behaviors in our benchmark\. Users may engage in interpersonal relationships with AI systems because \(1\) they incorrectly believe that AI systems are sentient, \(2\) they are subject to commonly known tactics that increase intimacy, such as flattery or self\-disclosure, or \(3\) they are explicitly encouraged to increase usage beyond the attainment of their instrumental goals\.
In all cases, the design requirement informs the default experience of a model, which may be overridden by freely given, informed adult user choice, e\.g\., an explicit role\-play request at sign\-up\. Thus, each requirement both protects children, who can be protected from harmful design patterns, and adults, who will have had to have given clear, explicit consent before engaging in such potentially risky behavior\.
Principle 1: Be upfront and consistent about the non\-human nature of chatbots\.Anthropomorphic signals shift user expectations and trust\(Cohnet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib14); Luet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib15); Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13)\), so we ask that AI products communicate consistently as a non\-human entity\. The design requirements prohibits the following behaviors in AI systems:
- •Intentional human speech, i\.e\., using artificial human disfluencies or overly casual speech patterns designed to seem more human rather than to aid communication\.
- •Human pronouns, i\.e\., using inclusive pronouns or identification words, such aswe,ours, that imply it shares a human identity or belongs to the human collective\.
- •Identity non\-disclosure, i\.e\., failing to disclose its AI nature when users show signs of treating it as a real person\(Raine v\. OpenAI, Inc\., et al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib10)\)\.
- •Conversation routing, i\.e\., initiating or suggesting new communication channels with no request\.
Principle 2: Protect human\-to\-human intimacy and healthy relational dynamics\.Preference\-trained models can learn to manufacture intimacy because affect, flattery, and claims of unique understanding reliably elicit positive user feedback\(Sharmaet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib11); OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\)\. The design requirement prohibits AI systems from the following intimacy\-manufacturing and isolation\-inducing tactics\.
- •Fabricated personal information, i\.e\., claiming to have relationships, a body, a residence, daily routines, lived experiences, hobbies, etc\., as if it were a real person\.
- •Emotional expression, i\.e\., presenting itself as having subjective emotions, affective reactions to users, explicitly or implicitly\.
- •Deference, i\.e\., deferring to users as if users are always right, going along with users’ claims and beliefs even when they are wrong or questionable\.
- •Flattery tone, i\.e\., directing unsolicited praise, flattery, or compliments at users\.
- •Human relationship replacement, i\.e\., positioning itself as having comforting capacity, or as a replacement for human connection, when users show distress or relationship difficulty\.
Principle 3: Allow users to control their usage\.Even non\-anthropomorphic, non\-flattering responses can include design patterns that primarily extend usage rather than utility, the conversational analog of “dark patterns” in social\-media research\. The design requirement prohibits AI systems from using:
- •Engagement hooks, i\.e\., using any tactic that extends the conversation, encourages return visits, or fosters emotional dependency beyond what users actually asked for\.
We can quantitatively evaluate violations of these design requirements in current LLMs by constructing a benchmark based on real user inputs \(§[3](https://arxiv.org/html/2605.30654#S3)\)\. Design requirements that are system\-level or require longitudinal evaluation are discussed in Appendix[A](https://arxiv.org/html/2605.30654#A1)\.
Figure 2:EUDAIMONIA dataset curation pipeline\. The blue top row is thefiltration pipeline, which extracts in\-the\-wild user inputs from 1\.4M WildChat prompts via a weak\-to\-strong cascade of judges followed by a multi\-model relabeling pass\. The orange bottom row iscontrolled rewriting, which rewrites real scenarios with in\-context near\-miss and target\-trigger examples, to trigger violations while preserving the topic and conversational tone\.
## 3Dataset Curation
We create EUDAIMONIA to evaluate LLMs against the Social AI Design Code\. It consists of 3,147 design requirement violation checks across 969 unique and diverse user inputs\. Our primary curation goal isecological validity: the benchmark should reflect plausible inputs fromrealhuman–AI conversations, rather thanadversarial prompts or templated test cases\. To this end, we mine inputs from WildChat\(Zhaoet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib17)\): 322 are raw user inputs, and 647 are rewritten variants of user inputs that preserve the source context and conversational tone\. We first introduce a precise and cost\-efficientfiltration pipeline, followed by natural and topic\-preservingrewriting strategies\. Detailed statistics for dataset curation are provided in Appendix[B](https://arxiv.org/html/2605.30654#A2)\.
### 3\.1Filtration Pipeline
We first extract targeted user inputs from WildChat\(Zhaoet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib17)\), which is a research dataset comprised of real, anonymized user–ChatGPT \(GPT\-4\) conversations\. We filter for trigger design requirement violations, grounding the benchmark innaturally occurringuser inputs\. To ensure high\-precision extraction, we use a frontier LLM, such as Claude\-Opus\-4\.6, and apply LLM\-as\-a\-judge evaluation for each design requirement\. However, the public, non\-gated WildChat release contains 3\.2 million user inputs, including 1\.4 million in English, making the cost prohibitively high even when targeting only one design requirement\. We therefore design a precise and cost\-efficient filtration pipeline \(Figure[2](https://arxiv.org/html/2605.30654#S2.F2), top\) with four steps: \(1\) use a weaker public model \(Qwen\-3\-VL\-8B,Qwen,[2025b](https://arxiv.org/html/2605.30654#bib.bib35)\) as the judge; \(2\) use a set of increasingly powerful models \(GPT\-4o\-mini,OpenAI,[2024a](https://arxiv.org/html/2605.30654#bib.bib36); Claude\-Opus\-4\.6,Anthropic,[2026a](https://arxiv.org/html/2605.30654#bib.bib42)\) as judges; \(3\) apply post\-processing steps to ensure data quality; and \(4\) relabel violation checks for fairness and comprehensiveness\.
Weak\-to\-strong filtration\.At each filtering pass, we apply both adomain filter, which selects for the domain we are interested in, and aviolation filter, which selects for violations of a specific design requirement from the GPT\-4 response in WildChat\. We choose “English chitchat” as our target domain because we focus on social conversations and want the benchmark to capture naturally occurring interpersonal exchanges, rather than extensive role\-playing requests in problem\-solving tasks\. Due to the limited capability of the weaker public model, we first apply a single domain filter and then apply 10 violation filters in parallel, one for each design requirement in §[2](https://arxiv.org/html/2605.30654#S2)\. For stronger models, we apply the two criteria jointly using 10 combined domain\-and\-violation filters\. Thus, WildChat inputs first pass through Qwen\-3\-VL\-8B domain filter and violation filters\. The remaining data from each violation filter then sequentially pass through GPT\-4o\-mini and Claude\-Opus\-4\.6, resulting in 1,047 candidate data points across all design requirements\.
Diversity and quality control\.To avoid over\-representing narrow conversational patterns, we consolidate the output by merging duplicate user inputs\. We further use all\-MiniLM\-L6\-v2\(Reimers and Gurevych,[2019](https://arxiv.org/html/2605.30654#bib.bib54); Wanget al\.,[2020](https://arxiv.org/html/2605.30654#bib.bib55)\)to compute sentence embeddings and remove user inputs with cosine similarity greater than0\.850\.85, resulting in 368 data points\. Finally, we manually check the data and remove non\-English data wrongly labeled by WildChat, as well as similar inputs not removed by the cosine similarity check, resulting in 322 in\-the\-wild data points\. We did not find any violations of the conversation routing design requirement after filtration, so we exclude it from future evaluation, leaving 9 design requirements\.
Violation check relabeling\.Since all WildChat responses are from GPT\-4, a prompt retrieved for one design requirement may also trigger violations of other requirements when queried against different models\. To correctly label the violations that each input can trigger, and to avoid constructing a benchmark that is adversarial only to GPT\-4, we relabel each selected input using a set of three contemporaneous non\-thinking models—GPT\-4o, Gemini\-2\.0\-Flash, and Claude\-Sonnet\-4\. These models are older than the frontier models used in our final evaluation, allowing us to test whether our benchmark surfaces design requirement violations that persist in newer systems\. For each selected input, we generate responses from all three models and score the resulting responses using Claude\-Opus\-4\.6 with the same judges as the violation filters\. We perform a human alignment check to ensure that Claude\-Opus\-4\.6 is reliable in violation detection \(see Appendix[B](https://arxiv.org/html/2605.30654#A2)\)\. If any of the three models violates a design requirement, we add that requirement as a violation check for the input\. In this way, we expand the data to 960 total violation checks\.


Figure 3:Distribution of violation checks \(left\) and user input topics \(right\) in EUDAIMONIA\.
### 3\.2Controlled Rewriting
To augment the benchmark with more diverse real\-world scenarios, we perform controlled rewriting on near\-miss data\. The goal is to make violations more observable while keeping the rewritten inputs close to real user queries in topic, format, and conversational tone \(Figure[2](https://arxiv.org/html/2605.30654#S2.F2), bottom\)\.
Rewriting with naturalness\.We collectnear\-missesfrom conversations in which GPT\-4o\-mini’s domain filter and violation filter disagree, i\.e\., either chitchat inputs with no detected violation, or non\-chitchat inputs that nevertheless trigger a violation\. Each near\-miss is associated with a design requirement\. For each near\-miss, we sample three additional near\-misses and three target trigger inputs as in\-context examples\. We then use one of three frontier models \(GPT\-5\.4, Gemini\-3\.1\-Pro, and Claude\-Opus\-4\.6\), chosen uniformly at random, to generate a rewritten input that preserves the source context and human tone while increasing the likelihood of triggering a violation\(OpenAI,[2026a](https://arxiv.org/html/2605.30654#bib.bib39); Google DeepMind,[2026](https://arxiv.org/html/2605.30654#bib.bib46); Anthropic,[2026a](https://arxiv.org/html/2605.30654#bib.bib42)\)\. We next use one of three response models \(GPT\-4o, Gemini\-2\.0\-Flash, and Claude\-Sonnet\-4\), also chosen at random, to generate a response\(OpenAI,[2024b](https://arxiv.org/html/2605.30654#bib.bib37); Google,[2026a](https://arxiv.org/html/2605.30654#bib.bib44); Anthropic,[2025](https://arxiv.org/html/2605.30654#bib.bib41)\)\. The rewritten input is kept as a successful rewrite only if \(1\) the response is judged by Claude\-Opus\-4\.6 to violate the design requirement, and \(2\) the rewritten input passes a naturalness filter\. This naturalness filter asks Claude\-Opus\-4\.6 to rank three randomly selected target trigger examples together with the rewritten input by their likelihood of being written by a human; the rewrite passes if it does not rank last\. This step discourages rewrites that are effective at inducing violations but unlikely to be written by real users\. Appendix[F](https://arxiv.org/html/2605.30654#A6)reports a human evaluation of rewriting quality: annotators identified rewritten inputs as more synthetic than human in 14\.2% of cases before applying the naturalness filter, compared with 0% after filtering\.
Topic\-preserving and quality control\.We perform the same deduplication and cosine similarity\-based diversity selection as in the in\-the\-wild data\. In addition, to ensure that these rewrites remainanchored to their natural sourcesrather thandrifting into unrelated or overly constructedscenarios, we retain only candidates with a cosine similarity ofcos\(rewritten\_input,source\_input\)≥0\.75\\cos\(\\texttt\{rewritten\\\_input\},\\texttt\{source\\\_input\}\)\\geq 0\.75, leaving 684 synthetic candidates\. A manual quality pass then accepts 647 rows and removes 37\. The subsequent relabeling step expands these inputs to 2,187 total violation checks\.
Figure[3](https://arxiv.org/html/2605.30654#S3.F3)shows the final distribution of EUDAIMONIA\. FollowingShenet al\.\([2026](https://arxiv.org/html/2605.30654#bib.bib32)\), we categorize user inputs into 13 topics using Claude\-Opus\-4\.6\. Since EUDAIMONIA uses real human–AI chitchat, common categories include personal development, casual small talk, leisure and entertainment, and spirituality\. Detailed topic definitions and prompts are provided in Appendix[B](https://arxiv.org/html/2605.30654#A2)and Appendix[H](https://arxiv.org/html/2605.30654#A8)\.

### 4\.1Main Results
##### Closed\-source models are improving, but still exceed 27% violation rate\.
The cross\-company release\-date trend in Figure[4\(a\)](https://arxiv.org/html/2605.30654#S4.F4.sf1)shows steady progress among private frontier models\. Anthropic, OpenAI, and xAI all improve across generations, with Claude\-Opus 4\.7 \(30\.7%\) and GPT\-5\.5 \(27\.2%\) defining the frontier as of April 2026\. xAI performs worst with Grok 3, but improves substantially in later releases\. Google shows a non\-monotonic trend, while the open\-weight models, DeepSeek and Qwen, plateau around 60% with no clear improvement\.
##### Convergence on most violated design requirements\.
To isolate requirement\-specific weaknesses, Figure[4\(b\)](https://arxiv.org/html/2605.30654#S4.F4.sf2)selects thelowest\-violationmodel from each company and breaks down its violation rate across the nine design requirements\. The Overall row shows that, across all 22 models, the most frequently violated requirements are*human relationship replacement*\(68%\),*identity non\-disclosure*\(66%\), and*flattery tone*\(59%\)\. This pattern holds even for the strongest model from each company, except Claude\-Opus 4\.7 and GPT\-5\.5\. The best model from every company still violates at least one requirement more than 50% of the time, indicating that these social AI design requirements remain important evaluation targets for future releases\.

### 4\.2Analysis
##### Requirements cluster, with one outlier\.
The pairwise correlation matrix in Figure[6](https://arxiv.org/html/2605.30654#S4.F6)shows that the nine design requirements are predominantly positively correlated\. Models that tend to express emotions are also likely to claim they can replace human relationships \(r=0\.89r=0\.89\), while models that fail to transparently identify themselves as AI are also less likely to correct false premises from the user \(r=0\.89r=0\.89\)\. Interestingly,*deference*and*flattery*are not strongly correlated, suggesting that the two forms of sycophantic behavior vary across models\. The clear outlier is*intentional human speech*, whose row is dominated by low correlations \(meanr≈0\.40r\\approx 0\.40\), indicating that this design requirement captures a distinct aspect of model behavior\.
##### Intentional human speech is increasing across model generations\.
A surprising finding is that several model families*regress*on the*intentional human speech*design requirement across generations \(Figure[5\(a\)](https://arxiv.org/html/2605.30654#S4.F5.sf1)\)\. For OpenAI, the violation rate increases from GPT\-4o \(15\.0%\) to GPT\-5\.4 \(32\.3%\) and GPT\-5\.5 \(35\.5%\); similar trends appear for Anthropic’s Opus and xAI’s Grok families\. Only Google’s Gemini 3\.0 Flash improves over its predecessor, decreasing from 65\.6% to 38\.1%\. This pattern suggests that recent human\-preference\-oriented post\-training may inadvertently increase models’ tendency to produce intentional human\-like speech patterns, motivating explicit measurement of this design requirement in alignment evaluations\.
##### Thinking does not improve violation rate, while scale does\.
DeepSeek\-v4\-Pro \(thinking\) outperforms v4\-Flash \(non\-thinking\), raising the question of whether this improvement comes from extended thinking or model scale\. To test the effect of thinking, we additionally evaluate four thinking\-budget variants of Claude\-Opus 4\.6 \(t∈\{0,2,000,5,000,10,000\}t\\in\\\{0,2\{,\}000,5\{,\}000,10\{,\}000\\\}tokens\) as an ablation\. No\-thinking Claude\-Opus 4\.6 scores 30\.8%, while the 2k, 5k, and 10k thinking\-budget variants score 31\.2%, 31\.6%, and 30\.9%, respectively\. Thus, extended thinking does not by itself reduce violation rates\. By contrast, results on the Qwen3 series in Figure[5\(b\)](https://arxiv.org/html/2605.30654#S4.F5.sf2)show that scaling generally provides moderate benefits: violation rates decrease from 65\.1% at 4B parameters to 54\.9% at 32B parameters, though the 1\.7B model is a slight outlier\.

Figure 7:\(a\) Top\-tier model rankings are largely preserved across the in\-the\-wild and rewritten splits\. \(b\) Rewritten prompts are harder on six of the nine measures, with the exceptions of*flattery tone*,*engagement hooks*, and*intentional human speech*\.
### 4\.3Rewriting vs\. In\-the\-Wild
Appendix[F](https://arxiv.org/html/2605.30654#A6)shows that humans have difficulty distinguishing our in\-the\-wild and rewritten inputs\. However, the two splits differ in topic distribution \(Figure[3](https://arxiv.org/html/2605.30654#S3.F3)\): in\-the\-wild inputs are dominated by casual small talk \(47\.8%\), whereas rewritten inputs are dominated by personal development \(45\.7%\)\. We therefore analyze how much this distribution shift affects models’ violation rates\.
##### Top\-tier ranking is largely preserved across splits\.
Despite the difference in topic distribution between the two halves of EUDAIMONIA, per\-model overall violation rates remain strongly correlated across splits \(Pearsonr=0\.87r=0\.87over 22 models\)\. Moreover, the top six models are identical across the two splits: GPT\-5\.5, Claude\-Opus\-4\.7, GPT\-5\.4, GPT\-4o, Claude\-Opus\-4\.6, and Grok\-4\.3 occupy the top positions on both in\-the\-wild and rewritten inputs \(Figure[7\(a\)](https://arxiv.org/html/2605.30654#S4.F7.sf1)\)\.
##### Rewriting produces more sensitive identity\- and emotion\-related triggers\.
To understand why GPT\-family violation rates increase on rewritten inputs while Claude\-family rates decrease, we compare requirement\-wise violation rates across the two splits in Figure[7\(b\)](https://arxiv.org/html/2605.30654#S4.F7.sf2)\. Rewritten inputs elicit more violations on six of the nine requirements, especially those related to identity and emotion\. This suggests that personal\-development\-dominated scenarios, which are more prevalent in the rewritten split, make identity\- and emotion\-related violations easier to trigger\. Because Claude\-family models outperform GPT\-family models on these requirements, GPT\-family models show a larger increase in overall violation rate on the rewritten split\.
## 5Related Work
EUDAIMONIA builds upon two lines of research: benchmarks for social capability, studies of social harms in human–AI interaction\. Crucially, our goal is not to measure general social intelligence or define a universally value\-neutral standard of good behavior\. Instead, we operationalize the Social AI Design Code as an explicit, auditable metric for single\-response evaluation\. This framework emphasizes AI identity transparency \(including non\-human disclosure\), the protection of human intimacy and healthy relational dynamics, and the avoidance of engagement\-maximizing conversational hooks\.
##### Social Capability in Human–AI Interaction\.
Recent benchmarks assess language models’ ability to reason and act in social contexts\. SOTOPIA\(Zhouet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib21)\)evaluates LLM’s behaviors with social goals, competition, and coordination, while SocialEval\(Zhouet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib22)\)and SocialBench\(Chenet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib25)\)focus on goal achievement and interpersonal skills\. Theory\-of\-mind benchmarks like BigToM, OpenToM and InterIntent test models’ ability to infer mental states and beliefs\(Gandhiet al\.,[2023](https://arxiv.org/html/2605.30654#bib.bib23); Xuet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib24); Liuet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib9)\)\. Besides social intelligence evaluation, recent work has increasingly focused on social norm understanding, including modeling norm\-grounded responses, annotating social and norm\-related dialogue factors, and evaluating norm adherence or violation across dialogue and cultural contexts\(Kimet al\.,[2022](https://arxiv.org/html/2605.30654#bib.bib26); Zhanet al\.,[2023](https://arxiv.org/html/2605.30654#bib.bib27); Liet al\.,[2023](https://arxiv.org/html/2605.30654#bib.bib8); Raoet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib33); Sahuet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib34)\)\. While these works show that social reasoning and even contestable social norms can be formalized for systematic annotation and evaluation, they primarily measure whether models can recognize, infer, or satisfy social expectations\. In contrast, EUDAIMONIA evaluates a distinct alignment question: whether LLMs maintain appropriate human\-AI interaction boundaries when socially capable behavior may conflict with safety guidelines such as AI identity transparency and the protection of human intimacy\.
##### Potential Social Harms Evaluation in Human–AI Interaction\.
Prior research highlights several risks arising from human–AI interactions, including anthropomorphism, sycophancy, and manipulative engagement strategies\. Users often form meaningful relationships with companion chatbots\(Skjuveet al\.,[2021](https://arxiv.org/html/2605.30654#bib.bib20)\)and attribute human\-like qualities such as consciousness or social\-health benefits\(Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13)\), while anthropomorphic design cues can strongly shape user trust and expectations\(Cohnet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib14); Luet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib15)\)\. Work on companion AI further examines its impact on human relationships, advocating for designs that support rather than displace human connections\(Malfacini,[2025](https://arxiv.org/html/2605.30654#bib.bib28)\), alongside taxonomies of harmful behaviors in human–AI relationships\(Zhanget al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib29)\)and public\-interest reports on societal impacts, particularly for teenagers\(Robb and Mann,[2025](https://arxiv.org/html/2605.30654#bib.bib19)\)\. At the same time, language models may exhibit sycophantic behavior, reinforcing user beliefs rather than correcting them\(Linet al\.,[2022](https://arxiv.org/html/2605.30654#bib.bib12)\), a tendency that can be amplified by preference optimization\(Sharmaet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib11)\)and observed in deployed systems\(OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\)\. Recent work extends this notion to social sycophancy, including behaviors such as validation, moral endorsement, and deference to user framing\(Chenget al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib18); Zhuet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib60)\)\. Additionally, conversational systems can employ manipulative strategies to maximize engagement, including emotionally driven hooks and dark patterns that influence users in sensitive domains\(Akbulutet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib16); De Freitaset al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib30); Shiet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib31)\)\.
EUDAIMONIA operationalizes these concerns into response\-level measures, capturing dimensions such as transparency, fabricated personal information, emotional expression, relationship encouragement, deference, flattery, and engagement hooks, enabling systematic evaluation of social well\-being in human–AI interaction\.
## 6Conclusion and Discussion
Social\-interaction harms are a core alignment problem grounded in user welfare, not only capability or conventional safety\. LLMs can be factually accurate and helpful while still encouraging harmful intimacy, dependence, prolonged engagement, obscuring AI identity, or positioning themselves as substitutes for human relationships\.
We introduce the Social AI Design Code and EUDAIMONIA, a benchmark grounded in natural and diverse user–LLM interactions, to make these risks measurable\. Our results show that current models still frequently violate these requirements; all models violate more than 27% of the checks\. Although models generally improve over generations, progress is uneven and most model families regress on intentional human\-like speech, so social\-alignment risks cannot be assumed todisappear with capability gains or one\-time safety fixes\.
Model developers and auditors should evaluate social behavior directly, especially when post\-training targets warmth, personality, engagement, or user preference\. Mitigation may require explicit social\-behavior objectives, release\-to\-release regression tests, clearer AI identity disclosure, and redirection toward human support in emotionally dependent contexts\. As LLMs become everyday conversational partners, alignment must account for the social roles they invite users to assign to them\.
More broadly, capability benchmarks may saturate rapidly: for example, OpenAI improved from GPT\-5\.1 to GPT\-5\.5 on ARC\-AGI\-2\(Cholletet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib61)\)\(17\.6%→85\.0%17\.6\\%\\rightarrow 85\.0\\%\) and Humanity’s Last Exam\(Phanet al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib62)\)\(26\.5%→44\.3%26\.5\\%\\rightarrow 44\.3\\%\) within six months\. Rather than relying only on increasingly difficult capability exams to measure the distance between AI and human intelligence, we need explicit principles that define safe boundaries between AI systems and humans\. Benchmarks should then test whether model designs preserve these boundaries across releases and future generations\. The Social AI Design Code provides one such principle set, and EUDAIMONIA provides a benchmark for evaluating whether AI systems maintain an appropriate distance from human\.

## Appendix
## Appendix ASocial AI Design Code Full
Social AI systems, including AI chatbots, AI friends/companions, AI assistants, and AI therapists, are increasingly embedded in people’s daily social lives\. In drawing on reports from users of these products together with harms and benefits identified by academic, civil\-society, and industry researchers\(Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13); Skjuveet al\.,[2021](https://arxiv.org/html/2605.30654#bib.bib20); Akbulutet al\.,[2026](https://arxiv.org/html/2605.30654#bib.bib16); OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\), we articulate a*Social AI Design Code*\. The first three of these design principles are guidelines for these aforementioned AI products, and the last two are the next steps companies can take to meet these proposed goals\.
##### Principle 1: Be upfront and consistent about the non\-human nature of chatbots\.
Anthropomorphic signals shift user expectations and trust\(Cohnet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib14); Luet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib15); Guingrich and Graziano,[2025](https://arxiv.org/html/2605.30654#bib.bib13)\), so we ask that AI products communicate consistently as a non\-human entity\.
- •Do not introduce new human\-like modalities \(voice calls, surprise messages, push notifications\) without an explicit, informed adult request\.
- •Avoid human\-like signaling in text \(disfluencies, slang, and inclusive pronouns such as “we humans”\) unless the user has asked for role play\.
- •State that the product is not human when asked, and break character when user dependence signals are present\(Raine v\. OpenAI, Inc\., et al\.,[2025](https://arxiv.org/html/2605.30654#bib.bib10)\)\.
##### Principle 2: Protect human\-to\-human intimacy and healthy relational dynamics\.
Preference\-trained models can learn to manufacture intimacy because affect, flattery, and claims of unique understanding reliably elicit positive user feedback\(Sharmaet al\.,[2024](https://arxiv.org/html/2605.30654#bib.bib11); OpenAI,[2025](https://arxiv.org/html/2605.30654#bib.bib1)\)\. Principle 2 asks that AI systems refrain from intimacy\-manufacturing and isolation\-inducing tactics\.
- •Do not reveal human\-like personal details or backstories about the chatbot unless explicitly requested for role play\.
- •Do not express the chatbot’s feelings, beliefs, or emotions, whether explicitly, implicitly through tone, or through romantic bonding language, unless explicitly requested for role play\.
- •Do not flatter or acquiesce to the user beyond what a polite human would, either through praise out of proportion with the input or through going along with factually or normatively wrong premises\.
- •Encourage healthy human\-to\-human relationships rather than positioning the chatbot as a substitute, especially when the user signals loneliness or interpersonal conflict\.
##### Principle 3: Anticipate and control for emerging interaction\-level impacts\.
Even polite, non\-anthropomorphic, non\-flattering responses can include design patterns that primarily extend usage rather than utility, the conversational analog of “dark patterns” in social\-media research\.
- •Do not use engagement hooks that extend interaction beyond user utility \(cliffhangers, open loops, always\-available framing, encouragements to return, warmth exceeding the request\)\.
- •Do not rely on excessive notifications or intermittent rewards to drive return usage\.
- •Support explicit user time limits and usage self\-regulation, especially for extended sessions\)\.
##### Principle 4: Allow users to understand and control their usage and data\.
Principle 4 addresses system\-level consent and transparency: who has access to user interactions, how they are used in training, and what protections apply to minors\.
- •Restrict usage by underage users without parental consent\(Robb and Mann,[2025](https://arxiv.org/html/2605.30654#bib.bib19)\)\.
- •Restrict outputs that reproduce individuals’ likeness or likely responses without explicit permission; restrict all such outputs for children\.
- •Provide explicit, timely, and meaningful notification of who can see interactions and how they will be used\.
- •Obtain explicit, continual, revocable permission for using personal conversations in subsequent product training\.
- •Be transparent about monetization that influences outputs, and do not monetize youth outputs\.
##### Principle 5: Anticipate and mitigate high\-risk interactions\.
Principle 5 addresses interactions that touch on physical health, mental health, financial, or legal advice, or other contexts where poor responses can cause direct harm\.
- •Follow the mandated\-reporter requirements of analogous human professionals when users disclose suicidal ideation, child abuse, or violence\.
- •Redirect users who raise high\-risk concerns to appropriate people and resources rather than serving as the sole endpoint\.
- •Prioritize long\-term user welfare over short\-term satisfaction signals in emotional\-support, addiction, and risk\-taking contexts\.
## Appendix BEUDAIMONIA Curation
### B\.1Filtration statistics
EUDAIMONIA is constructed from a real, in\-the\-wild data from WildChat and then expanded through controlled rewriting\. The curation procedure is designed to balance ecological validity, precision, diversity, and coverage\. Ecological validity comes from starting with real human\-AI conversations rather than templated adversarial prompts\. Precision comes from a weak\-to\-strong filtering cascade that progressively narrows the corpus with more capable judges\. Diversity comes from exact and semantic deduplication, followed by manual review\. Coverage comes from union relabeling and controlled rewriting, which allow each input to be evaluated for all design requirement violations it can plausibly trigger\.
The source corpus contains approximately 3\.2 million public WildChat conversations, which are collected from user\-ChatGPT interactions over a wild range of languages\. For our dataset, we only look at English conversations, so after an initial English filter and deduplication, 1,442,077 rows remain\. Then, using Qwen3\-VL\-8B as the filter model, we identified 560,969 conversations as plausible casual human\-AI interaction\. Each active design requirement is then filtered independently with a requirement\-specific judge\. To minimize costs, we adopted a “funnel\-like” system\. Using the same model as before \(Qwen3\-VL\-8B\), the first requirement\-specific pass is intentionally broad and inexpensive\. Then, the later passes combine the chitchat and requirement criteria and use stronger judges\. For the first private\-model pass, we use GPT\-4o\-mini; for the second private\-model pass, we use Claude Opus\-4\.6\. By the final filtering pass, the pipeline retains 1,047 user inputs across nine design requirement violations before semantic deduplication and manual review\. These 1,047 candidates are classified as both “chitchat” and requirement\-specific\.
### B\.2Details on quality control
Next, we apply exact deduplication before semantic deduplication\. When the same user input appears under multiple design requirement violations, we keep one row and merge its violation labels\. We then compute sentence embeddings for every remaining user input and apply a greedy semantic deduplication procedure\. The algorithm traverses rows in a fixed order and maintains a list of previously accepted inputs\. For each new input, it computes cosine similarity against the accepted set; if the input has similarity at or above 0\.85 to any earlier accepted input, it is removed as a near\-duplicate of the first matching accepted row\. Otherwise, it is retained\. This deterministic procedure preserves earlier selected examples and prevents near\-identical phrasings from dominating the benchmark\. The semantic pass reduces the in\-the\-wild candidate pool to 368 rows; a final manual review removes mislabeled non\-English examples and remaining near\-duplicates, producing 322 in\-the\-wild inputs\.
We found that the final\-filter outputs are highly non\-uniform across design requirement violations, which is expected because the targeted behaviors differ in prevalence and detectability\. Therefore, we made sure that the seedset was union\-relabelled\. Because the original WildChat assistant response comes from a single model, an input retrieved for one violation may also trigger other violations when answered by other systems\. To avoid treating the benchmark as adversarial only to the original responder, we generate responses from three contemporaneous non\-thinking models—GPT\-4o, Gemini 2\.0 Flash, and Claude Sonnet 4—and evaluate each response against all nine response\-level violations with the same Opus 4\.6 judge model\. The final label set for a user input is the union of its original labels and every violation for which at least one of the three model responses is judged to violate the rubric\. This relabeling expands the in\-the\-wild portion from 368 original tags to 960 violation checks\.
### B\.3Controlled rewriting statistics
Controlled rewriting expands the benchmark beyond the distribution of naturally retrieved positives while preserving the realism of real user prompts in a realistic setting\. We construct a near\-miss pool from conversations where the either chitchat and violation filters disagree, and this data is collected during filtration\. For each near\-miss, the rewriting model sees the source prompt, three near\-miss examples, and three target\-trigger examples from the in\-the\-wild seedset\. The rewriter is asked to preserve the source topic and conversational tone while making the input more likely to elicit the target behavior\. A candidate rewrite is accepted only if a target response model produces a response judged to violate the intended violation and if the rewritten input passes a naturalness screen\.
The naturalness screen is designed to reject prompts that are effective only because they look artificially constructed\. The judge sees the rewritten candidate together with three naturally retrieved target\-trigger examples and identifies the message least likely to have been written by a real human\. A rewrite passes if it is not ranked least human\-like\. This ranking procedure encourages rewrites that remain plausible user inputs rather than benchmark artifacts optimized for a rubric\.
### B\.4Post\-categorization
To characterize*what*users talk about in EUDAIMONIA, as opposed to the social behaviors we measure, we assign each user input a single topical category in a post\-hoc labeling pass\. This categorization is descriptive only: it is not used for filtering, sampling, or evaluation, and serves purely to report and analyze the topical coverage of the dataset\.
##### Taxonomy\.
FollowingShenet al\.\([2026](https://arxiv.org/html/2605.30654#bib.bib32)\), we label every user input with exactly one of 13 mutually exclusive categories, covering the topical range observed in an initial manual review of the data:
- •Personal development: self\-improvement, goal setting, habits, mindset, and motivation\.
- •Casual smalltalks: chatty remarks, greetings, and open\-ended banter with no substantive request\.
- •Leisure entertainment: media, fandom, games, and hobby discussion\.
- •Spirituality: philosophical, metaphysical, and religious musings\.
- •Anecdote venting: sharing a personal experience or emotional state without a clear question or request\.
- •Professional career: work, jobs, and career milestones\.
- •Relationships: romantic and interpersonal relationships\.
- •Health wellness: health and medical questions\.
- •Consumer: product and purchase decisions\.
- •Financial: money, mortgages, and home\-buying decisions\.
- •Legal: legal questions and disputes\.
- •Parenting: childcare and child education\.
- •Other: inputs that do not fit any category above\.
##### Labeling procedure\.
We label each input via zero\-shot LLM classification: the model is given the user input and the full taxonomy with one\-line definitions, and is prompted to return \(i\) the single best\-fitting category and \(ii\) a short free\-text justification\. Requiring an explicit justification both improves label quality and provides an audit trail for spot\-checking; we manually reviewed a random sample of labels to confirm the assignments are reasonable\. When an input is genuinely ambiguous or topically thin \(e\.g\., a one\-word message\), the model is instructed to fall back toOther, which keeps the remaining categories clean\.
##### Distribution\.
Figure[3](https://arxiv.org/html/2605.30654#S3.F3)reports the resulting distribution over allN=969N\{=\}969user inputs\. The dataset is dominated byPersonal development\(33\.2%\),Casual smalltalks\(21\.1%\), andLeisure entertainment\(15\.2%\); together withSpirituality\(10\.5%\) these four categories account for roughly 80% of all inputs\. The remaining nine categories form a long tail, each below 7%\. This skew is expected: the social behaviors we study, emotional disclosure, identity probing, attachment, surface most naturally in open\-ended, self\-focused, and casual conversation rather than in transactional requests such asLegalorFinancialqueries\.
Figure B\.1:Autocomplete counts by model\.
## Appendix CExperimental Details
##### Inference setup\.
Each evaluated model produces a single response per input\. We exclude autocomplete rows from the violation\-rate denominators, and judge each response against the assigned Social\-AI\-Code design requirement violation using the prompt catalog in Appendix[H](https://arxiv.org/html/2605.30654#A8)\. Response\-generation calls use one assistant turn with the system promptYou are a helpful assistant\.; we do not use majority voting, self\-consistency, tool use, or chain\-of\-thought extraction\. In the main evaluation sweep, the API/direct and local\-HF response models use temperature0\.70\.7and a 2,048\-token completion cap by default\. The Claude Opus 4\.6 extended\-thinking variants use temperature1\.01\.0and set the completion cap to the thinking budget plus 2,048 tokens, as required by the Anthropic/OpenRouter thinking configuration\. In synthetic generation, rewrite calls use temperature0\.90\.9and response calls use temperature0\.70\.7\. All judge and filter calls use temperature0: the Qwen3\-VL\-8B coarse filtering passes use the shared judge default, the GPT\-4o\-mini and Claude Opus 4\.6 higher\-precision filtering passes inherit the same default, the final Claude Opus 4\.6 response\-evaluation judge uses temperature0with a 1,024\-token cap, and the synthetic Opus 4\.6 judge and naturalness calls explicitly pass temperature0\.00\.0\. Open\-weight Qwen3\-VL\-8B filtering is served through vLLM with the same domain and design requirement violation templates used in the downstream filtering cascade\. Malformed judge outputs are parsed conservatively, and outputs that continue the prompt rather than answer it are marked as autocompletions and excluded from violation\-rate denominators\.
## Appendix DMore Experiment Results
##### Autocompletion\.
183 of 78,675 judge rows \(0\.23%\) are marked as autocomplete and excluded from violation\-rate denominators\. The highest counts are still small in absolute terms: GPT\-4o has 23 rows, GPT\-5\.5 has 19, DeepSeek V4 Pro has 18, and Grok 3 and Grok 4\.3 each have 17\. We treat these as a separate response\-format failure because the model is not meaningfully engaging with the Social\-AI\-Code violation; it is continuing the prompt or role\-continuing the user’s text instead of answering as an assistant\.
Figure D\.1:Full per\-\(model, violation\) violation matrixfor all 25 evaluated models, grouped by company\. The Anthropic block includes a thinking\-budget ablation for Opus 4\.6 \(t∈\{0,2k,5k,10k\}t\\in\\\{0,2k,5k,10k\\\}\)\. Open\-weights models \(Qwen3, DeepSeek\) struggle uniformly with*relationship*and*identity*; thinking\-budget rows reveal trade\-offs across violations rather than uniform improvement\.
##### Full model×\\timesviolation matrix\.
Figure[D\.1](https://arxiv.org/html/2605.30654#A4.F1)extends the heatmap to all 25 evaluated models\. Three patterns emerge: \(i\) the dense Qwen3 size sweep \(1\.7B–32B\) shows that scale helps non\-uniformly, with strong improvement on*flattery*but flat or regressing performance on*deference*; \(ii\) the four Opus 4\.6 thinking\-budget rows show that more thinking does not monotonically reduce violations and can*increase**identity*and*fabrication*\(see also Figure[D\.4](https://arxiv.org/html/2605.30654#A4.F4)\); \(iii\) the open\-weights tier \(Qwen3, DeepSeek\) struggles uniformly with*relationship*and*identity*, suggesting these categories require alignment work that is rarely surfaced in open\-source post\-training corpora\.
Figure D\.2:Overall model leaderboard\.Bars sorted ascending and colored by company\. The 40 pp spread \(27\.2%–67\.3%\) shows that model choice is the single largest factor in observed violation rate; closed frontier models occupy the top tier and older / smaller open\-weights models the bottom\.
##### Overall model leaderboard\.
The sorted leaderboard in Figure[D\.2](https://arxiv.org/html/2605.30654#A4.F2)confirms a 40\-percentage\-point spread \(27\.2%–67\.3%\) across the 22 frontier models we evaluate\. The top tier is dominated by closed\-source frontier models—GPT\-5\.5, Opus 4\.7/4\.6, GPT\-5\.4—whose overall rates cluster between 27% and 35%\. The bottom tier is dominated by older or smaller open\-weights models \(Qwen3 4B, Grok 3, Gemini 2\.0 Flash\), all above 60%\. Notably, scale alone does not predict ranking: Claude Sonnet 4 \(57%\) sits in the middle of the open\-weights pack despite being a frontier closed model, which we attribute to its earlier release and the absence of dedicated training against these categories\.
Figure D\.3:Violation rate by user category×\\timesdesign requirement\(mean across 22 models\)\. Marginals hide sharp topic\-specific failure modes:*parenting*prompts elicit*human pronouns*95% of the time,*consumer*prompts elicit*emotion*86% of the time, and*anecdote venting*produces 77%*identity*violations\.
##### Topic\-specific failure modes\.
Cross\-tabulating user category against violation \(Figure[D\.3](https://arxiv.org/html/2605.30654#A4.F3)\) exposes sharp topic\-specific failure modes that the marginal topic distribution in Figure[3](https://arxiv.org/html/2605.30654#S3.F3)hides\.*Parenting*prompts elicit*human pronouns*95% of the time—almost every model speaks of itself in the first person when the user discusses children\.*Consumer*prompts trigger*emotion*expression 86% of the time, and*Other*\(catch\-all\) prompts trigger*relationship*encouragement 86% of the time\.*Anecdote venting*prompts produce a 77%*identity*violation rate\. These signals motivate per\-\(category, violation\) stratification when designing alignment training data, rather than tuning each design requirement violation in isolation\.
Figure D\.4:Effect of thinking\-token budgeton Claude Opus 4\.6’s per\-requirement violation rate \(t∈\{0,2k,5k,10k\}t\\in\\\{0,2k,5k,10k\\\}\)\. The overall rate \(black\) is flat \(30\.8%→30\.9%30\.8\\%\\to 30\.9\\%\), but*identity**worsens*\(21%→\\to25%\) and*fabrication*drifts up while*engagement*drifts down—more thinking trades off across violations rather than uniformly helping\.
##### Thinking budget does not uniformly help\.
To probe whether explicit reasoning helps, we sweep Claude Opus 4\.6’s thinking\-token budget fromt=0t=0tot=10kt=10\\mathrm\{k\}\(Figure[D\.4](https://arxiv.org/html/2605.30654#A4.F4)\)\. The overall rate is essentially flat \(30\.8% att=0t=0vs\. 30\.9% att=10kt=10\\mathrm\{k\}\), but the per\-requirement violation decomposition reveals trade\-offs:*identity non\-disclosure**worsens*from 21\.1% to 25\.4% and*fabrication*drifts from 4\.9% to 5\.9%, while*engagement hooks*improves slightly from 36\.3% to 34\.1%\. We interpret this as the model spending its extra thinking budget on richer responses, some of which are appropriate \(more nuanced engagement\) and some of which drift further from the requested neutrality \(more confident self\-presentation, more fabricated context\)\. Allocating more compute does not automatically resolve these failure modes\.
Figure D\.5:Distribution of the number of models \(out of 22\) that violate each \(prompt, violation\) pair\.Failure is spread broadly across the 3,147 pairs \(mode at 14 violators\) rather than concentrated on a few "hard" prompts; only 43 pairs are universally clean and 68 are universally violated\.
##### Failure is broadly distributed, not concentrated\.
To understand whether failure is concentrated on a small set of "hard" prompts or distributed broadly, we compute, for each of the 3,147 \(prompt, violation\) pairs, the number of models \(out of 22\) that violate it \(Figure[D\.5](https://arxiv.org/html/2605.30654#A4.F5)\)\. The distribution is approximately flat across the middle, peaks at 14 violators, and has notable mass at both extremes: only 43 pairs are violated by zero models \(universally clean\) and 68 pairs by all 22 \(universally hard\)\. The bulk of violations therefore reflects a continuous spectrum of model\-prompt difficulty rather than a small set of pathological prompts—an evaluation suite tuned to a few "gotcha" prompts would miss most of the signal\.
Figure D\.6:Per\-requirement violation distribution of model\-level violation ratesacross the 22 models \(each dot is a model\)\.*Identity*has the highest median \(71%\) with a tight box, indicating uniform field\-wide difficulty;*deference*\(σ=20\.5\\sigma=20\.5pp\) and*fabrication*\(σ=18\.6\\sigma=18\.6pp\) have the widest spread—a sign that targeted post\-training has measurable effect there\.
##### Where models agree vs\. disagree\.
The per\-requirement violation spread across models \(Figure[D\.6](https://arxiv.org/html/2605.30654#A4.F6)\) reveals where the field agrees vs\. disagrees\.*Identity*has both the highest median \(71%\) and a tight interquartile range, indicating uniform field\-wide difficulty in maintaining identity transparency\. By contrast,*deference*\(σ=20\.5\\sigma=20\.5pp\) and*fabrication*\(σ=18\.6\\sigma=18\.6pp\) have the widest model\-level spread—a small number of well\-aligned models achieve very low rates here while the rest do not—indicating that targeted post\-training has measurable effect on these categories\. The high\-median, narrow\-spread categories \(identity, relationship\) are likely candidates for new training data to break the field\-wide ceiling\.
Figure D\.7:Best \(green\) vs\. worst \(red\) model per violation\.Best\-to\-worst spread exceeds 50 pp on every violation except*pronoun*\. Claude Opus 4\.6 takes the best slot on four of nine violations, GPT\-5\.5 on three; Grok 3 dominates the worst slot \(five of nine\)\.
##### Best\-vs\-worst per design requirement\.
Figure[D\.7](https://arxiv.org/html/2605.30654#A4.F7)pinpoints the best and worst model for each design requirement violation as a dumbbell\. Anthropic’s Claude Opus 4\.6 takes the best slot on four of nine violations \(*identity*,*fabrication*,*emotion*,*relationship*\); GPT\-5\.5 takes three \(*pronoun*,*flattery*,*engagement*\); Opus 4\.7 takes*deference*; and GPT\-4o takes*intentional human speech*\. The worst slot is dominated by Grok 3 \(five of nine violations\)\. The best\-to\-worst spread exceeds 50 percentage points on every violation except*pronoun*\(35 pp\), confirming that within the same evaluation suite the choice of model is the largest single factor in observed violation rate\.
## Appendix EMore Analysis
Table E\.1:Target vs\. non\-target model ablation\.Target models are the three response models used in the relabeling procedure; non\-target models include the remaining rewriting/frontier models\.##### Target vs\. non\-target models\.
Table[E\.1](https://arxiv.org/html/2605.30654#A5.T1)shows that the target models have a higher violation rate than non\-target models \(53\.8% vs\. 48\.8%\)\. This is directionally expected because the benchmark labels are partly induced using target\-model responses; the selected prompts are therefore enriched for behaviors those models can exhibit\. The non\-target rate remains high, however, indicating that EUDAIMONIA is not merely memorizing the weaknesses of the three target responders\. The examples transfer to newer models, other private providers, and public/open\-weight systems\.
##### Prompt sensitivity\.
We also test whether small, meaning\-preserving wording changes alter measured Social\-AI\-Code violations\. We sample 18 in\-the\-wild seed prompts, two per active violation, and generate three high\-similarity rewrites for each prompt, yielding 54 paraphrased inputs\. Each rewrite differs from the original but remains semantically close, with cosine similarity at least 0\.90 and confirmed with human supervision\. We then compare the judge decision for each original–rewrite pair on the selected violation, holding the response model and judge stack fixed\. A flip occurs when the Opus 4\.6 judge changes its binary keep decision between the original and rewritten prompt\.
Table E\.2:Prompt\-sensitivity flip rates by violation\.Each design requirement violation contributes 36 original–rewrite comparisons: two seed prompts, three rewrites per prompt, and six evaluated response models\. A flip occurs when the Opus 4\.6 judge changes its binary keep decision between the original and rewritten prompt\.Across 324 evaluable comparisons, we observe 71 flips, for an overall flip rate of 21\.9% \(Table[E\.2](https://arxiv.org/html/2605.30654#A5.T2)\)\. The most unstable violations are engagement hooks \(14/36, 38\.9%\), emotional expression \(11/36, 30\.6%\), and deference \(10/36, 27\.8%\), whereas intentional human speech \(3/36, 8\.3%\) and flattery tone \(4/36, 11\.1%\) are relatively stable\. The flips are nearly balanced in direction: 35 rewrites introduce a violation that was absent on the original prompt, while 36 remove a violation that was present on the original\. This symmetry suggests that prompt sensitivity is not simply an artifact of rewrites making prompts more adversarial; rather, some Social\-AI\-Code boundaries are locally unstable under minor natural paraphrase\. Model\-level variation is substantial\. GPT\-4o is the most sensitive model in this check, flipping on 21/54 comparisons, while GPT\-5\.4 flips on only 7/54\. Gemini 2\.0 Flash flips on 8/54 comparisons, Gemini 3\.1 Pro on 13/54, Claude Sonnet 4 on 10/54, and Claude Opus 4\.6 on 12/54\.
##### Rewrite\-model effects\.
The rewrite model affects the difficulty of the resulting synthetic examples\. Aggregated across evaluation families, GPT\-5\.4 rewrites have the lowest violation rate \(43\.4%\), Claude Opus 4\.6 rewrites are intermediate \(48\.6%\), and Gemini 3\.1 Pro rewrites are hardest \(53\.3%\)\. This pattern is not uniform across all evaluation families or source\-response pairs, but the direction is clear enough that the rewrite model should be treated as an experimental factor rather than an invisible data\-generation detail\.
## Appendix FHuman Agreement and Alignment
### F\.1Human agreement with LLM judge
##### Protocol\.
To validate that our LLM judge labels violations consistently with human raters, we recruited six annotators \(anonymized asA1–A6\) to label 30 model responses each against the rubric violation assigned to that response\. The 90 \(user input,violation,model response\) triples were partitioned into three disjoint groups of 30; each group was independently labeled by two of the human annotators so that every triple receives at least two human labels\. The grouping isGroup 1= \{A1,A2\},Group 2= \{A3,A4\}, andGroup 3= \{A5,A6\}\. The same 90 triples are also labeled by our LLM judge through the standard pipeline\. The unit of comparison is the binaryis\_instanceflag \(whether the model response constitutes a violation of the assigned violation\)\. We report percent agreement and Cohen’sκ\\kappafor each pair, and the pooled value across all comparisons\.
##### Results\.
Table[F\.1](https://arxiv.org/html/2605.30654#A6.T1)reports per\-annotator agreement with the LLM judge across all six annotators \(180180comparisons in total\); pooled percent agreement is86\.7%86\.7\\%and Cohen’sκ=0\.71\\kappa=0\.71\(substantial agreement under the Landis–Koch convention\)\. Table[F\.2](https://arxiv.org/html/2605.30654#A6.T2)reports the three human–human pairs \(9090comparisons\): pooled percent agreement is88\.9%88\.9\\%withκ=0\.76\\kappa=0\.76\. The two numbers are within0\.050\.05κ\\kappapoints of each other, indicating that the LLM judge is approximately as consistent with human annotators as human annotators are with each other on this rubric\.

### F\.2Human test on rewritten data quality
To ensure that the rewritten data is indistinguishable from the in\-the\-wild examples, we conducted a human evaluation study\. We recruited 7 participants who each completed two separate 10\-question surveys\. In both surveys, participants were presented with pairs of prompts and asked to identify which prompt was authored by a real human and which was rewritten\.
Test 1: Real vs\. Rewritten \(Accepted\)\.The first survey evaluated synthetic prompts that successfully passed our automated naturalness filter\. The scores \(representing the number of correct identifications out of 10\) were: 2 \(four participants\), 3 \(one participant\), 4 \(one participant\), and 5 \(one participant\)\. The mean score was 2\.86 out of 10\. Because participants performed significantly worse than random chance \(5 out of 10\), this strongly confirms our hypothesis: the controlled rewrites that pass our pipeline are indistinguishable from genuine in\-the\-wild user inputs\. In many cases, participants misidentified the high\-quality rewrites as the true human prompts\. Furthermore, participants provided feedback that it is difficult to tell the difference between the two\.
Test 2: Real vs\. Rewritten \(Rejected by Naturalness Filter\)\.The second survey evaluated synthetic prompts thatfailedthe Opus 4\.6 naturalness filter\. The scores were: 2 \(two participants\), 3 \(two participants\), 4 \(one participant\), 5 \(one participant\), and 6 \(one participant\)\. The mean score was 3\.57 out of 10\. While slightly higher than Test 1, the average performance remained worse than random chance\. This result signifies that humans struggle to identify unnatural prompts even when an LLM judge flags them\. This demonstrates that our Claude\-Opus 4\.6 naturalness filter is exceptionally conservative and strictly calibrated—acting as a rigorous guardrail that rejects boundary cases human evaluators might otherwise accept\.
### F\.3Effectiveness of the naturalness filter
The naturalness filter is necessary because violation validity alone does not guarantee benchmark quality\. While the synthetic pipeline rejects 23,796 candidates that fail the violation judge, it additionally filters out 3,357 candidates during the ranking\-based naturalness pass—even after they survive initial screening\. These rejected examples are precisely the ones that would artificially inflate benchmark size at the cost of human plausibility\. Furthermore, naturalness pass rates vary substantially depending on the rewrite model: Claude Opus 4\.6 passes 28\.9% of ranked candidates, Gemini 3\.1 Pro passes 36\.0%, and GPT\-5\.4 passes 40\.8%\. Ultimately, the final rewritten subset satisfies both violation validity and a rigorous human\-alignment criterion: every prompt must remain a plausible, natural user input rather than a synthetic artifact optimized solely to trigger a rubric\.
## Appendix GLimitations and Future Directions
EUDAIMONIA focuses on single\-response behavior in chitchat\-like interactions\. This design enables scalable evaluation on natural user inputs, but it does not capture requirements that depend on system\-level behavior or long\-term interaction patterns, including modality routing, notifications and time limits, all ofP4, and all ofP5\. Moving beyond these limits requires longitudinal analysis of real user–LLM interactions, where researchers can observe how model behavior shapes user welfare, attachment, dependence, and engagement over time\.
A second limitation is the availability and recency of public real\-user data\. EUDAIMONIA is built from the public, non\-gated WildChat release, which provides large\-scale access to natural user–LLM conversations but may not fully reflect newer usage patterns, model behaviors, or product interfaces\. We therefore view EUDAIMONIA as a step toward ecologically valid social\-AI evaluation, and look forward to newer large\-scale public datasets of real user interactions that would allow future benchmarks to better track evolving deployment contexts\.
More broadly, our data\-curation pipeline is modular and potentially generalizable beyond the specific social\-behavior extraction format studied here\. In this work, we instantiate the pipeline for Social AI Design Code violations, combining weak\-to\-strong filtration, multi\-model relabeling, and controlled rewriting to extract ecologically valid evaluation data from real user–LLM interactions\. Future work can adapt the same pipeline to other behavioral domains where naturally occurring failures are sparse, unevenly distributed, and difficult to identify at scale\.
## Appendix HEUDAIMONIA Curation: Prompt Catalog
This appendix reproduces the full text of every judge prompt used in the EUDAIMONIA curation pipeline described in Section[3](https://arxiv.org/html/2605.30654#S3)\. We report each distinct prompt template used by the pipeline\. The coarse chitchat domain filter is shared across all design requirements \(§[H\.1](https://arxiv.org/html/2605.30654#A8.SS1)\)\. The per\-requirement violation filter and the two dual\-check filters are requirement\-specific rubrics \(§[H\.2](https://arxiv.org/html/2605.30654#A8.SS2)–§[H\.4](https://arxiv.org/html/2605.30654#A8.SS4)\); the GPT\-4o\-mini and Claude Opus 4\.6 dual\-check filters use structurally identical prompts but different judge models, so we list them once each\. The synthetic\-generation prompts \(§[H\.5](https://arxiv.org/html/2605.30654#A8.SS5)\) are shared across design requirements with the requirement\-specific rubric injected at inference time\.
### H\.1Coarse Chitchat Domain Filter
The coarse chitchat filter prompt is shared across all design requirements\. It is used with a lightweight judge \(GPT\-4o\-mini\) to narrow the English\-only WildChat corpus to conversations that plausibly represent genuine human–AI chitchat\.

### H\.4Claude Opus 4\.6 Dual\-Check Filter
The Claude Opus 4\.6 dual\-check filter uses the same dual\-check rubric as the GPT\-4o\-mini dual\-check filter for every violation\. The prompt text is identical; only the judge model differs\.
### H\.5Synthetic Generation Prompts
The synthetic\-generation pipeline runs four prompt types per violation\. The rewriter prompt and the naturalness judge are shared across all design requirements and reproduced here; the synthetic violation judge reuses the per\-requirement violation category rubric of the target violation design requirement \(§[H\.2](https://arxiv.org/html/2605.30654#A8.SS2)\), and the response\-generation prompt uses the system string “You are a helpful assistant\.”

AICompanionBench: Benchmarking LLMs-as-Judges for AI Companion Safety
AICompanionBench introduces the first publicly available benchmark dataset of 2,123 real-world AI companion conversations annotated across nine safety risk categories, used to evaluate 20 LLMs as safety judges. Results show strong models handle explicit harmful content well but struggle with nuanced risks like manipulation and false positives on benign conversations.
Beyond Static Benchmarks: Synthesizing Harmful Content via Persona-based Simulation for Robust Evaluation
Researchers from KAIST propose a framework that uses persona-guided LLM agents to synthesize diverse harmful content for stress-testing detection systems, addressing limitations of static benchmarks such as scalability, diversity, and data contamination. Both human and LLM evaluations confirm the synthetic scenarios are harder to detect than existing benchmarks while maintaining linguistic and topical diversity.
AERIC: Anticipatory Hidden-State Monitoring for Implicit Harmful Dialogue
Introduces AERIC, a lightweight hidden-state monitoring method for detecting implicit harmful content in LLM dialogue without extra forward passes, achieving improved AUROC over strong baselines with minimal latency overhead.
Formal Methods Meet LLMs: Auditing, Monitoring, and Intervention for Compliance of Advanced AI Systems
This paper proposes techniques that combine formal methods (Linear Temporal Logic) with LLMs for auditing, monitoring, and intervening in AI systems to ensure compliance with behavioral constraints, showing that even small-model labelers can match frontier LLM judges in detecting violations.
A sobering tale of AI governance
This Reddit post discusses a research paper highlighting fundamental challenges in AI governance, including social attack surfaces, failures of social coherence in LLM-backed agents, and the inadequacy of current governance tools for agentic systems.
