OpenAI recently open-sourced `chatgpt-retrieval-plugin`, a module for creating a retriever based on your own data github.com/openai/chatgpt… Can you combine this with @langchain's 40+ DocumentLoaders? Yes. Yes you can. Gist for doing so: gist.github.com/hwchase17/1429…

Yesterday @karpathy tweeted about using SVMs instead of KNN for retrieval (pros: better results, flexibility; cons: takes longer) Today @RLanceMartin implemented it in @langchain 🚀🚀 Play around with it here! python.langchain.com/en/latest/modu…

Retrieval for QA systems is hard Vector search is good for capturing semantically similar texts, but often queries specify desired attributes like time, authorship, or other "metadata" fields, which vector search is not great at Enter... ⭐️SelfQueryRetriever⭐️

OpenAI recently released a guide on building agents which contains some misguided takes There's a lot of FUD, confusion, hype, and noise around agents I wrote a blog on how to think about agent frameworks. Includes: Background Info - What is an agent? - What is hard about
