Hi HN! It’s been three years since we launched LangChain as an open source package. Since then, we’ve evolved into a broader platform for agent engineering (LangGraph, LangSmith). …

Author here! Main takeaways (which I'd love feedback on) are: There are series of agents recently (claude code, manus, deep research) which execute tasks over longer time horizons …

that was a quote from anthropic's blog (not us saying it)... our Ghost theme does not make it super apparent what is a quote :/

lol taken completely out of context I was actually arguing *for* MCP in this blog But I don't think its good for all use cases! hence the quote

we're working on a way to make these conditional flows less tedious :) some good devX improvements coming soon!

Little project I hacked on recently. "Who's the AI?" is a game where you try to identify the AI in a conversation. You will be placed in a chatroom with 2 other players. Both, neit…

Excited to launch this! Happy to answer any questions HN community might have

what did it look like though? I'm really keen to hear what the common patterns you saw emerging were

> My advice is to focus less on the “chaining” aspect and more on the “provider agnostic” part a lot of our effort recently has been going into standardizing model wrappers, includ…

would love any feedback if you do!

> Different agents for different situations... totally agree. we've opted for keeping langgraph very low level and not adding these higher level abstractions. we do have examples f…

totally agree on not hiding prompts, and have tried to stop doing that as much as possible in LangChain and are not doing that at all in LangGraph thanks for the thoughts, apprecia…

ooc, what was the "same single solution"

sorry to hear that, totally understand feeling burnt ooc - do you think theres anything we could do to change that? that is one of the biggest things we are wrestling with. (aside …

Hi HN, Harrison (CEO/co-founder of LangChain) here, wanted to chime in briefly I appreciate Fabian and the Octomind team sharing their experience in a level-headed and precise way.…

Cofounder of LangChain here! LangSmith is designed to be independent of LangChain. Some resources: tracing without LangChain: https://github.com/langchain-ai/langsmith-cookbook/blo…

hi all - Harrison (co-founder) of LangChain here We released this as a way to make it easier to get started with LLM applications. Specifically, we've heard that when people were u…

LangChain co-founder here. There's lots of good feedback here (that also resonates with previous feedback) that we're working hard to address. On some key points: - We genuinely ap…

working on it as we speak!

Something we've been working on for the past few weeks - an easy way to visualize, debug, and explore the execution trace of LangChain agents and chains
