v0.2.0 — Multi-Provider Embeddings

What's new

8 embedding providers (up from 2): OpenAI, Gemini, Cohere, Voyage AI, Mistral, Jina AI, Ollama, and any OpenAI-compatible API.

• Factory pattern with auto-detection from environment variables
• All SDKs loaded lazily — no startup overhead
• Settings UI dropdown with all providers
• New optional SDKs as optionalDependencies
• Full docs updated with provider comparison tables

Breaking changes

None. The existing OpenAI and Gemini embedders work exactly as before.
