## Provider overview

| Provider | BYOK | Typical use | Notes |
| --- | --- | --- | --- |
| OpenAI | Yes | General reasoning, writing, coding | Common default lane for broad model coverage |
| Anthropic | Yes | Long-form reasoning and careful editing | Useful when you want a more deliberate model family |
| Google | Yes | Fast multimodal and mixed-input work | Good to keep available when image-aware work matters |
| OpenRouter | Yes | Cross-provider model access | Helpful when you want a single gateway for several families |

## Selection guidance

Choose providers for ownership, routing, and ecosystem fit. Choose models for behavior.

The cleanest setup is usually a short list of providers you trust and a curated model set inside each one.
