Provider matrix

Every provider preset is defined in packages/cli/src/providers-registry.ts. The default model for each is in known-models.ts.

Feature notes

• Streaming. All OpenAI-compat providers support stream: true. Anthropic exposes its own streaming SSE format which the core runtime normalizes.
• Tools. "Tools" here means the provider-native tool-use protocol (Anthropic tool_use / OpenAI tools). Groq, DeepSeek, xAI, and Mistral all speak the OpenAI tool-call shape. OpenRouter forwards tool calls if the underlying model supports them.
• Images. Inline image support in the user message. OpenAI and Anthropic are the stable paths. OpenRouter is per-model.
• Audio. OpenAI gpt-4o-audio-preview is the only cloud target for now. Post-v1.0 we'll add Google Gemini if/when the provider preset lands.

Auth flows

• API key — paste flow or --api-key non-interactive.
• Browser PKCE — OpenRouter only. Spins a localhost callback port and opens a browser tab.
• env-only — local providers. The CLI doesn't store anything; you either set the *_API_KEY env var (usually empty for local) or let the defaults take over.

[placeholder — landing 2026-Q2] Nightly provider-matrix tests are aspirational. The plan (PHASE_7_PLAN.md §8.2) calls for nightly jobs that exercise streaming / tools / images against each provider; these land alongside slice 8 once the Zod schema generator also catches every provider-preset change.
