LangChain Support for Workers AI, Vectorize and D1

Developer Week saw the announcement of LangChain support for Cloudflare Workers, an open-source framework that enables developers to create powerful AI workflows by combining various models and plugins with a declarative API. Since then, five new key integrations between LangChain and Cloudflare have been introduced: Workers AI Chat Models, Workers AI Instruct Models, Text Embeddings Models, Vectorize Vector Store, and Cloudflare D1-backed Chat Memory. These additions allow developers to create full-stack AI applications by leveraging various Cloudflare tools within LangChain.js. Additionally, a Cloudflare + LangChain + Nuxt Multi-source Chatbot template has been released to demonstrate the integration of different pieces of Cloudflare Workers AI and expand on the concept of retrieval augmented generation (RAG) for building conversational retrieval systems that can draw from multiple data sources.
