# Agentic race

> Run competing models on one task and have a judge select the strongest answer.

Run multiple configured models concurrently:

```bash theme={null}
arka race "design a test plan for this API" \
  --models openrouter/model-a,ollama/qwen3:8b,groq/llama-3.3-70b-versatile \
  --judge openrouter/model-a --json
```

Each contestant is bound to its declared provider/model. The judge receives
only the task and contestant outputs and scores correctness, completeness,
testability, and safety. Failed contestants are retained in the report, and a
judge failure is explicit rather than silently selecting an answer.

Natural language works: “race several agents on a coding task.” Use the result
as a recommendation; Arka does not write, deploy, register, or submit anything
automatically from a race winner.
