# Multi-LLM alternatives

> Run the same request through several configured models and compare outputs.

Run the same request through several configured models and compare labeled
outputs:

```bash theme={null}
export ARKA_MULTI_LLM_MODELS="openai/gpt-4o-mini,anthropic/claude-3-5-haiku"
arka multi-llm "propose three names for this product"
arka multi-llm "write a concise API design" --json
```

Use `provider/model` entries separated by commas. A failed model is reported
without discarding successful alternatives. Natural language such as “give me
several model alternatives for this landing page” is routed automatically.
