# Auto Arena Skill

End-to-end automated model comparison using the OpenJudge `AutoArenaPipeline`:

1. **Generate queries** — LLM creates diverse test queries from task description
2. **Collect responses** — query all target endpoints concurrently
3. **Generate rubrics** — LLM produces evaluation criteria from task + sample queries
4. **Pairwise evaluation** — judge model compares every model pair (with position-bias swap)
5. **Analyze & rank** — compute win rates, win matrix, and rankings
6. **Report & charts** — Markdown report + win-rate bar chart + optional matrix heatmap

## Prerequisites

```bash
# Install OpenJudge
pip install py-openjudge

# Extra dependency for auto_arena (chart generation)
pip install matplotlib
```

## Quick start

### CLI

```bash
# Run evaluation
python -m cookbooks.auto_arena --config config.yaml --save

# Use pre-generated queries
python -m cookbooks.auto_arena --config config.yaml \
  --queries_file queries.json --save

# Start fresh, ignore checkpoint
python -m cookbooks.auto_arena --config config.yaml --fresh --save

# Re-run only pairwise evaluation with new judge model
# (keeps queries, responses, and rubrics)
python -m cookbooks.auto_arena --config config.yaml --rerun-judge --save
```

### Python API

```python
import asyncio
from cookbooks.auto_arena.auto_arena_pipeline import AutoArenaPipeline

async def main():
    pipeline = AutoArenaPipeline.from_config("config.yaml")
    result = await pipeline.evaluate()

    print(f"Best model: {result.best_pipeline}")
    for rank, (model, win_rate) in enumerate(result.rankings, 1):
        print(f"{rank}. {model}: {win_rate:.1%}")

asyncio.run(main())
```

### Minimal Python API (no config file)

```python
import asyncio
from cookbooks.auto_arena.auto_arena_pipeline import AutoArenaPipeline
from cookbooks.auto_arena.schema import OpenAIEndpoint

async def main():
    pipeline = AutoArenaPipeline(
        task_description="Customer service chatbot for e-commerce",
        target_endpoints={
            "gpt4": OpenAIEndpoint(
                base_url="https://api.openai.com/v1",
                api_key="sk-...",
                model="gpt-4",
            ),
            "qwen": OpenAIEndpoint(
                base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
                api_key="sk-...",
                model="qwen-max",
            ),
        },
        judge_endpoint=OpenAIEndpoint(
            base_url="https://api.openai.com/v1",
            api_key="sk-...",
            model="gpt-4",
        ),
        num_queries=20,
    )
    result = await pipeline.evaluate()
    print(f"Best: {result.best_pipeline}")

asyncio.run(main())
```

## Interpreting results

**Win rate:** percentage of pairwise comparisons a model wins. Each pair is evaluated in both orders (original + swapped) to eliminate position bias.

**Rankings example:**
```
  1. gpt4_baseline       [################----] 80.0%
  2. qwen_candidate      [############--------] 60.0%
  3. llama_finetuned      [##########----------] 50.0%
```

**Win matrix:** `win_matrix[A][B]` = how often model A beats model B across all queries.

## Checkpoint & resume

The pipeline saves progress after each step. Interrupted runs resume automatically:

- `--fresh` — ignore checkpoint, start from scratch
- `--rerun-judge` — re-run only the pairwise evaluation step (useful when switching judge models); keeps queries, responses, and rubrics intact
- Adding new endpoints to config triggers incremental response collection; existing responses are preserved
