@hwchase17 @nfcampos Such a good read
@hwchase17 @nfcampos Really long way we’ve come and long way to go. Such a good read with nostalgia hitting me reading ‘how langchain started’ and thinking we used to had ‘run’ instead of ‘invoke’. I felt lucky to see this ecosystem born and grow in front of my eyes. Keep building team & @hwchase17🦾
New deep dive into the design decisions that went into making 🦜🔗 @LangChainAI LangGraph a production-ready agent framework! Been a real honor to watch @nfcampos cook these last few years. If you've ever wondered "why StateGraph" or "what's a Pregel", find out 👇

One of the nice parts of `langchain` 1.0 is standard content blocks for reasoning, citations, multimodal stuff, etc Has been annoying to see providers implement slightly different variants of these, this should help make it easy to treat these in a standard way
