🧪 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:

1. 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 the Trace Inversion technology. 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.

2. 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.

🗺️ Training Pipeline Overview

The training of this model integrates a phased learning pipeline of Trace Inversion data augmentation technology and high-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.

Because agent trajectory datasets are complex and diverse. The datasets have undergone rigorous cleaning and formatting.

🎯 Three-Stage Curriculum Learning

Qwopus3.5-9B-coder adopts 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 retains short-sample replay to ensure the model maintains its short-context instruction-following capability and minimizes capability drift.

🤝 Collaboration & Training Details

This model is the result of continuous exploration in Agentic AI and reasoning capabilities.

Training Infrastructure & Configuration:

• 🖥️ Hardware: Local compute devices / Cloud GPUs (e.g. GB10 / H100 / RTX 5090 / A100)
• ⚙️ Framework: Unsloth for efficient fine-tuning

⚠️ IMPORTANT

Compatibility and Deployment Notice

• Tool Calling Format : When using this model for tool calling, please ensure that you use a Prompt format and System Prompt that match the training data to activate its Agent capabilities.
