Hello again, everyone!

We’ve got another really fun 9b, this one specifically trained for tool calling and agentic coding workflows in @NousResearch Hermes agent.

Happy to report that it crushes, and as a 9b it runs on super affordable hardware. We also hit this one with some coding domain-specific training, and it scored a 53.33% on SWE bench on a slice of 200 samples!

To me, I was really shocked to see this high of a score on a 9B model in swe, correct me if I’m wrong, but I think that’s nipping at the heels of the Gemma 4 series, much larger models on this particular benchmark, which is really incredible to see!

It also crushes the HermesAgent-20 benchmark, scoring an 85 vs the base model’s 71!

Make sure to run it hot, –temp around 1, that seems to be the sweet spot for running these particular fine tunes in harnesses. If you have trouble, you can work your way down, but it does a much better job departing from base models, overthinking when you run it, high temp ~1.

Please spin it up in Hermes and let us know your thoughts! Looking forward to hearing your feedback as always!

Also, those of you waiting for Qwopus 3.6 27B, I have put together a preliminary evaluation for you in my HF repo, go check it out; we will be releasing the full model very soon! I will put the preliminary repo in the comments!

https://huggingface.co/Jackrong/Qwopus3.5-9B-Coder-GGUF#%F0%9F%A7%AA-core-dataset-usage-trace-inversion-and-high-quality-agent-traces🧪 Core Dataset Usage: Trace Inversion and High-Quality Agent Traces

In order to break through the “reasoning bubble” limitation of the model in actual programming and tool usage, and to endow it with real Agent behavioral capabilities, this model introduced core augmented datasets during training:

https://huggingface.co/Jackrong/Qwopus3.5-9B-Coder-GGUF#1-reasoning-synthetic-data-combining-trace-inversion1. Reasoning Synthetic Data Combining Trace Inversion

Currently, based on public information, commercial models such as OpenAI’s GPT series and Anthropic’s Claude series have very clearly hidden the true internal reasoning chains of their models. For these models, what we can ultimately see in the API or front-end interface can often only be considered a highly compressed “Reasoning Bubble”.

To break through this limitation, we adopted theTrace Inversiontechnology. This technology utilizes an external “surrogate model” to reconstruct a complete and logically coherent deep reasoning chain based on the “question + final answer + compressed reasoning summary” published by commercial models. The “reasoning bubble”, which originally consisted of only a few sentences and logical leaps, is expanded into a high-quality deep learning trace with complete derivation, calculation, and logical verification, providing step-by-step logical learning signals for the model.

https://huggingface.co/Jackrong/Qwopus3.5-9B-Coder-GGUF#2-glm-51-agent-real-trace-data-lambdahermes-agent-reasoning-traces2. GLM-5.1 Agent Real Trace Data: lambda/hermes-agent-reasoning-traces

To significantly enhance the model’s execution and coding capabilities in real environments, this model additionally introduced the**lambda/hermes\-agent\-reasoning\-traces**dataset.

• Data Source and Scale: This data subset contains approximately 10,000 high-quality multi-turn Tool Calling Trajectories generated based on the ZhipuAI GLM-5.1 and kimi-4.6 models.
• Real Agent Behavior: Unlike traditional synthetic data, these samples represent real Agent conversations. Each sample not only contains the step-by-step reasoning process in the<think\>tags, but also includes actual tool execution results (rather than fabricated outputs out of thin air).
• Extensive Domain Coverage:- Terminal & Coding: Script writing, code debugging, environment configuration, and data processing. - Repository Tasks: Involving real code repository work, such as bug fixes, refactoring, and code review. - Browser Automation: Web navigation, scraping, and form filling. - Agent Tools: Memory persistence, task delegation, skill management, etc.

By learning these Agent trajectories that contain real feedback and thoughtful processes, Qwopus3.5-9B-coder can exhibit thinking and operational modes closer to human experts when facing complex programming and system operations tasks.

https://huggingface.co/Jackrong/Qwopus3.5-9B-Coder-GGUF#%F0%9F%97%BA%EF%B8%8F-training-pipeline-overview🗺️ Training Pipeline Overview

The training of this model integrates a phased learning pipeline ofTrace Inversiondata augmentation technology andhigh-quality Agent Trajectories data. Its core logic lies in restoring the highly compressed “reasoning bubble” of commercial models into a deep path for learning, and combining it with real agent operational traces to comprehensively improve the model’s logical reasoning and code execution capabilities.

Qwopus3.5-9B-coderadopts a phased reasoning data mixture strategy similar to Curriculum Learning, gradually increasing the difficulty and complexity of training signals:

1. **Early Stage (Format Establishment):**Focuses on short-to-medium length reasoning samples with stable formats. The primary goal of this stage is to establish a reliable, structured new reasoning format while avoiding overwhelming the model with extreme complexity.
2. **Middle Stage (Complexity Scaling & Multi-Teacher Distillation):**Gradually increases the proportion of complex reasoning samples from multiple teacher models. - The distillation data is sourced from more powerful models whose style distribution closely matches the base model, ensuring that the capability gap is not too wide, thereby achieving efficient learning.
3. Late Stage (Long-Context Reinforcement & Drift Prevention):Reinforces reasoning capabilities in long contexts. Crucially, this stage retainsshort-sample replayto ensure the model maintains its short-context instruction-following capability and minimizes capability drift.
