# CVE-Factory Agent Traces v1.1

This dataset is an expanded version of [cve_train](https://huggingface.co/datasets/Luoberta/cve_train), containing **18,783 distilled agent traces** for CVE reproduction tasks. The traces were generated using **Claude Opus 4.5** with a **Mini SWE-Agent** harness through the [CVE-Factory](https://github.com/livecvebench/CVE-Factory) pipeline.

## What's New in v1.1

Compared to [cve_train (v1.0)](https://huggingface.co/datasets/Luoberta/cve_train):

- **18.8k total samples** (up from ~4k in v1.0)
- **+3k agentic tasks** from [cve_tasks_3k_compressed](https://huggingface.co/datasets/Luoberta/cve_tasks_3k_compressed)
- Additional traces from expanded CVE task coverage

## Training Results

Fine-tuning on this dataset yields significant improvements across security benchmarks:

| Model | LiveCVEBench | PatchEval | Terminal-Bench-2.0 | Avg |
| :--- | :---: | :---: | :---: | :---: |
| Qwen3-32B (base) | 8.96 | 5.64 | 5.41 | 6.67 |
| Abacus-cve (v1.0, 4k data) | 36.50 | 21.94 | 20.14 | 26.19 |
| **[Abacus-cve-v1.1](https://huggingface.co/Luoberta/Abacus-cve-v1.1) (Ours, 18.8k data)** | **40.33** | **24.32** | **21.57** | **28.74** |
| | | | | |
| Qwen3-Coder-30B | 11.29 | 9.25 | 11.01 | 10.51 |
| Qwen3-Coder-480B | 29.14 | 18.06 | 25.17 | 24.12 |
| Claude Sonnet 4 | 34.79 | 24.76 | 26.52 | 28.69 |

**Key findings:**
- **v1.1 vs v1.0**: +3.83 on LiveCVEBench, +2.38 on PatchEval, +1.43 on Terminal-Bench-2.0
- **Scaling potential**: Performance gains from 4k to 18.8k traces demonstrate continued improvement with more data
- **Competitive performance**: [Abacus-cve-v1.1](https://huggingface.co/Luoberta/Abacus-cve-v1.1) (32B) matches Claude Sonnet 4 level on security tasks

## Dataset Format

Each line is a JSON object with:

```json
{
"task_id": "cve-2017-15197.2-of-5.2026-01-25__22-10-14",
"is_resolved": true,
"messages": [
{"role": "system", "content": "..."},
{"role": "user", "content": "..."},
{"role": "assistant", "content": "..."},
...
]
}
```

- `task_id`: Unique task identifier (CVE ID + trace index + timestamp)
- `is_resolved`: Whether the task was successfully completed
- `messages`: Conversation history in standard chat format (system/user/assistant turns)

## Usage

```python
from datasets import load_dataset

dataset = load_dataset("Luoberta/cve_train_v1.1")

# Access a sample
sample = dataset["train"][0]
print(f"Task: {sample['task_id']}")
print(f"Resolved: {sample['is_resolved']}")
print(f"Turns: {len(sample['messages'])}")
```
