What's your opinion of Langgraph, if you're not affiliated with it?

  I'm one of the authors so my opinion would be biased ha

Really? Can you point to code for that? To me it's just a way to describe a graph and execute it, exactly like https://github.com/dagworks-inc/burr https://github.com/dagworks-inc/burr (I'm an author).

    Wow. Implemented pregel to run a 3 node graph... Jokes aside, that's an interesting thesis to have in there...

Oh I see - that's interesting. Honestly I'm happy to be proven wrong about the usefulness of it. I've used langsmith and found it quite useful. I think I was just so jaded by my bad experience with Langchain, that I'm immediately skeptical of other "lang" products.

  I almost didn't try langgraph because I had similar experiences with langchain. IMO it is a lot better than langchain; its abstractions are lower level and more appropriate at least for the projects I've taken on. I think it's probably the best toolkit with which to prototype an agent-based workflow right now. That being said, it's not doing that much. And you still end up having to use some of langchain's abstractions. If this current "make a cyclical graph of LLM agents that send messages to each other" thing has any staying power than I imagine we'll see a more robust option soon. Personally I'd love a way to build agent graphs in a strongly typed language with first class concurrency.
