packages/ai:
- feat: added custom API provider registry (api-registry.ts)
- feat: stream() and streamSimple() check custom registry before built-in switch
packages/coding-agent:
- feat: added registerProvider() to ExtensionAPI for registering custom model providers
- feat: added ProviderConfig and ProviderModelConfig types
- feat: ModelRegistry.registerProvider() registers models and custom streaming functions
- feat: extension loader queues provider registrations, runner processes them on initialize
This enables extensions to register custom LLM providers with their own streaming
implementations. For example, a Vertex AI Claude extension can register a provider
that uses @anthropic-ai/vertex-sdk for Google Cloud ADC authentication:
pi.registerProvider("google-vertex-claude", {
baseUrl: "https://us-east5-aiplatform.googleapis.com",
apiKey: "GOOGLE_CLOUD_PROJECT",
api: "vertex-claude-api",
models: [...],
streamSimple: streamVertexClaude,
});
Backported from pi-mono's extension provider registration system.
