The starter config is Openai embeddings + llm, pinecone vector store, gradio for the UI. But it's customizable so you can swap out whatever you want easily.

What is Pinecone used for? I would assume that an average repo yields only a few hundred or thousand chunks. Even with brite force similarity search that is just 2-digit milliseconds on CPU. Faster than any API call. And even if you got into the million chunk scale, there’s FAISS and HNSW. So wouldn’t outsourcing this to an external provider not only be unnecessary, but making things slower?
