Poop makes humans win

Summary

A paper inspired a game called TuringDuel where humans and AI compete in a one-word Turing test, revealing that humans lead AI 47–38 in wins, with 'poop' being an undefeated word choice.

Found a paper recently that asked the question of a "minimal Turing test", basically, by just typing one word, can you prove to be a human? Got lost in a rabbit hole and had AI help build TuringDuel where humans play AI at being human, judged by AI. The good news, Humans lead AI 47–38 in this one-word Turing test. And you guessed it, “Poop” as a pick is undefeated. Gameplay is simple, you and an AI each pick one word, then another AI sees both in random order and guesses which came from the human. You score if it picks yours; the bot scores if it fools the judge. First to four wins. After 85 completed gamesin TuringDuel, here’s what happened: Humans lead 47–38 (55.3%). Across individual scored rounds, it’s much closer: 249–237, or 51.2% human wins. Toughest regular opponent: Mistral Medium, winning 13/20 games (65%). Gemini 2.5 Flash follows at 7/11. Humans had the easiest time against Claude 3 Haiku, beating it 11/14 times. The judges have quirks. Gemini 2.5 Flash correctly identified humans in 61% of valid decisions; Claude Haiku 4.5 managed 46%. Across all judges, the second word shown was picked 61% of the time, despite randomized order. Humans used more varied vocabulary: 418 distinct words, versus 208 for AI, across 487 submissions each. Humans’ favorite was “cat”; bots kept reaching for “chair,” “coffee,” and “mug.” Top detail: “poop” won 3/3 rounds. “Human” won 1/5. “Word” lost all four. Apparently, announcing your humanity isn’t very convincing. I've now made the thought process public to make the game a bit more engaging. (the game is free, no ads, no way to pay, tokens on me.) What word would you choose to prove you’re human?

Researchers from MIT, Carnegie Mellon, NYU, and Stanford developed an AI that decisively defeats top human Stratego players, a game of hidden information, using efficient training methods far cheaper than prior approaches like DeepMind's. The system, published in Nature, generalizes to other strategic games and could aid real-world decision-making under uncertainty such as business negotiations and cybersecurity.

OpenAI Five becomes the first AI to defeat world-champion esports professionals in Dota 2, winning two back-to-back matches against OG at the OpenAI Five Finals. The breakthrough was achieved through unprecedented scaling of training compute rather than novel algorithms, and the team is retiring OpenAI Five while announcing plans to deploy it for public internet play.

AI out-persuades world-champion debaters, Oxford study finds

A preregistered Oxford study found that AI systems reliably outperformed world-champion debaters and expert human persuaders across multiple experiments, with the AI's edge attributed to speed and volume rather than rhetorical skill. The results have significant implications for fundraising, communications, and governance of persuasive AI.
