## Model Description

This model is fine-tuned from [Qwen2.5-Coder-32B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-32B-Instruct) using the TermiGen pipeline, which synthesizes high-fidelity training data through two phases:

**Phase I: Environment Synthesis**  
- Multi-agent system generates 3,500+ verified Docker environments
- Tasks span 11 categories: system administration, security forensics, scientific computing, MLOps, etc.
- 420 unique command-line tools across 16 functional domains
- Automated unit test validation ensures task solvability

**Phase II: Error-Correction Trajectory Collection**  
- Generator-Critic framework with 20% error injection rate
- Teaches error → diagnosis → recovery cycles
- 3,291 trajectories (avg. 25.5 turns, 8,722 tokens each)
- Teacher model: Claude-4.5-Sonnet

- Sequence Length: 20,000 tokens
- Epochs: 5
- Precision: BF16 with DeepSpeed ZeRO-3
- Hardware: 8× AMD MI325X GPUs

**Dataset Statistics:**
- 3,500+ verified environments across 11 task categories

## Evaluation Results

### TerminalBench Performance

| Benchmark | Pass@1 |
|-----------|--------|
| TerminalBench 1.0 | **31.3%** |
| TerminalBench 2.0 | **18.0%** |


---

## Usage

We implemented a minimal BashAgent framework based on TerminalBench for agentic terminal execution. The agent interacts with Docker containers via bash shell, generating ReAct-style responses at each turn.

For detailed usage and integration examples, please refer to our [GitHub repository](https://github.com/ucsb-mlsec/terminal-bench-env).
