Providers ​

ysa supports multiple AI providers. Claude is the default; Mistral is also built in.

Built-in providers ​

Claude ​

bash
ysa run "add tests" --provider claude  # (default, --provider flag not yet in CLI)

Auth: Set CLAUDE_CODE_OAUTH_TOKEN in your environment, or log in with claude CLI before running ysa.

Default model: claude-sonnet-4-6

Mistral ​

Auth: Set MISTRAL_API_KEY in your environment.

Default model: devstral-small-latest

Switching providers via API ​

ts
await runTask({
  ...
  provider: "mistral",
  model: "devstral-small-latest",
});

Switching providers via CLI ​

The CLI currently defaults to Claude. To use Mistral, use the API directly or set default_model in the ysa config database.

Custom providers ​

See Providers API reference for how to implement and register a custom ProviderAdapter.
