By default, Chief’s LLM router picks the best model for each prompt. If you would rather Chief use a specific provider’s models, choose one from the AI Provider selector.

Choose an AI Provider

Chief: AI Provider — Automatic Anthropic OpenAI Google with model tiers
  1. Click the + button in the prompt bar. The command menu opens.
  2. Choose Customize, then open AI Provider.
  3. Pick a provider:
    • Automatic — Chief’s router picks the best option for you (the default).
    • Anthropic — Claude models.
    • OpenAI — GPT models.
    • Google — Gemini models.
  4. When you pick a specific provider, a Strategy choice appears:
    • Prefer — use the preferred provider when possible, fall back to others if needed.
    • Only — exclusively use the selected provider, never fall back.
💡 Good to know: AI Provider and the Intelligence: level are independent. Intelligence (Automatic, Fast, Expert, Research) sets how much reasoning to apply; AI Provider sets whose models do the work. Within each provider, Chief still maps your Intelligence level to that provider’s Fast, Expert, or Research model.

​
Switch back to Automatic

Open AI Provider again and choose Automatic (or Switch to Auto) to hand model selection back to the router.

FAQ

That happens with the Prefer strategy: if your provider is momentarily unavailable, Chief falls back to another so your prompt still runs. Choose Only if you never want a fallback — though prompts may fail when that provider is unavailable.
Providers can be temporarily unavailable. Switch to Automatic to let the router pick the best available option, then switch back later.
Leave it on Automatic unless you have a specific reason to prefer one — the router is built to pick the best model for each prompt.
