openrouter/freeAbout Embeddings
This platform uses OpenRouter's free chat models to generate text embeddings for semantic search. Documents are split into chunks, embedded, and stored in-memory. For production use, consider a dedicated embedding model and vector database like Pinecone (as used in the reference platform).
