Groq, Mistral, Together and DeepSeek

Groq, Mistral, Together and DeepSeek are all available from the preset list under Settings → Providers. Each one requires a key.

Anything else

Point Custom OpenAI-compatible at anything speaking the OpenAI chat API. Paste a key if the endpoint needs one, then use Fetch models.

Endpoints with no /models route are fine: the model picker and Default model both offer Type a model name, and hand-typed names are remembered per provider.
