LLM providers
This page covers BYOK (bring-your-own vendor API keys). For sign-in and use without your own keys, see Newton LLM. Newton and BYOK can coexist.
With BYOK, you supply OpenAI, Anthropic, Google Gemini, DeepSeek, Moonshot, MiniMax, etc. Keys stay on your device; requests go directly to the vendor and do not use the Newton platform.
Metaphysics theory vs LLM

| LLM | Understanding, planning, writing readings |
Configured separately in the UI.
Add a model (Settings → Models)

- Display name — appears in the saved configs list.
Primary & fallback
- Set a primary model as the default route.
- Enable auto fallback to try other saved configs when the primary fails.
Security

- Requests go from your device to the vendor; local usage stats are under Settings → Usage.
