Went through the docs today. Chef’s kiss

Jacob Lee11 months ago

Awesome job @sydneyrunkle @huntlovell and @WHinthorn! Love working with you all ❤️

Arjun Natarajan11 months ago

new docs are soooooo clean! what i'd consider the single biggest improvement we've made!

Paul Raistrick11 months ago

Well done, I've been building with LangChain and LangGraph from the early days. This is great to see!

Aaryan Kakad11 months ago

great man looks too interesting especially the “create_agent” abstraction would be a lot helpful for me to build multi step agentic AI applications and workflows love the pace at which langchain is working good luck

Julia Schottenstein11 months ago

first!

Huge - congrats on the team efforts!

Amazing work on getting LangChain and LangGraph to 1.0!

naveen manwani11 months ago

is there a full video of your discussion ?

Unclecode (Hossein)11 months ago

I remember when LangChain become 1.0.0, there is this such powerful satisfaction when your job hit this specific version, don’t think you can have that on other versions, perhaps closest one is 0.1.0! Congrats.

Pedro Agurto11 months ago

Huge guys, the docs are on point

Mohamed Anis11 months ago

The real milestone isn’t 1.0 it’s when enterprises trust it enough to build mission-critical systems on it

Harrison Chase11 months ago

already do!

Sydney Runkle11 months ago

Great convo -- exciting evolution and revolution of LangChain's oss suite!

Victor Kim11 months ago

Awesome! Great job, team👏 will read the doc

O.K11 months ago

Would langgraph cloud self hosted version now support langgraph 1.0

Harrison Chase11 months ago

yup!

O.K11 months ago

Great , would try it out

JeffK11 months ago

I haven’t checked them out yet but had to laugh out loud at NEW DOCS in all caps. Congrats and I hope the new docs live up to the 1.0 standard.🎉

Harrison Chase11 months ago

Had to emphasis it!

Kenil Vora11 months ago

Amazing work by the team on the revamped look of LangChain and LangGraph!

Min Chon Chi11 months ago

Excited to see the new agent with middleware support.

Timur Kiselchuk11 months ago

Congratulations on the 1.0 release! The emphasis on NEW DOCS is totally deserved - good documentation can make or break adoption. The addition of standard content blocks for swapping between models sounds like it'll make development so much smoother.

Suhrab Khan⚡️11 months ago

This is a major leap for agent engineering! The new middleware flexibility and standardized content blocks will redefine how developers build adaptive AI workflows.

Caspar11 months ago

create_agent middleware is fantastic

Bartek Sadlej11 months ago

Congrats! Does that mean support for e.g. OpenAI responses API with structured output?

Saïd Aitmbarek11 months ago

doope, so bullish on langchain!

Ohhh sweeet

Nathan Wang11 months ago

Also recommend people to build their own agent framework based on LangChain or LangGraph for specific user cases.

Atai Barkai11 months ago

Amazing, congratulations to you and the team!!

sasidhar11 months ago

This is nice. I hope all the other repo's like langchain-milvus etc are made langchain1.0 compatible soon, so I can fully migrate to langchain1.0

Andrew Nguonly11 months ago

LangGraph 1.0 🚀✅

Our latest LangChain Academy course – Building Ambient Agents with LangGraph – is now available! Most agents today handle one request at a time through chat interfaces. But as models have improved, agents can now run in the background – and take on long-running, complex tasks. LangGraph is built for these “ambient agents,” with support for human-in-the-loop workflows and memory. LangGraph Platform provides the infrastructure to run these agents at scale, and LangSmith helps you observe, evaluate, and improve your agents. Together, they make it easier to build reliable, production-ready agents. In this course, you’ll: 📩 Learn the fundamentals of LangGraph and how to build your own email agent 📊 Evaluate your agent using LangSmith ✅ Add human-in-the-loop for reviews, and memory so your agent adapts over time 🚀 Deploy your agent with LangGraph Platform and connect it to Gmail

🌟Our latest LangChain Academy course – Deep Agents with LangGraph – is now live!🌟 Many agents today follow the same simple pattern: run in a loop, call tools. That architecture works well enough, but it breaks down as tasks get more complex. Today, companies of all sizes – from startups to large enterprises – are building their own Deep Agents. These agents dive deeper. They’re able to plan complex tasks and carry them out over longer time horizons. There are four key features that set Deep Agents apart from regular agents: 1. Planning – keeps agents on track 2. File system – allows agents to offload context 3. Sub-agents – act as focused specialists 4. Prompting – provides agents with detailed instructions Our latest LangChain Academy course, Deep Agents with LangGraph, shows you how to combine these pieces with LangGraph to orchestrate long-running, multi-agent workflows. Big thanks to community member Dmitry Labazkin for helping us shape this course with his contributions! Enroll for free ➡️

New AI Agentic course! Learn to use LangGraph to build single and multi-agent LLM applications in AI Agents in LangGraph. This short course, taught by LangChain founder Harrison Chase Harrison Chase and Tavily founder @weiss_rotem, shows how to integrate agentic search to enhance an agent's knowledge with query-focused answers in predictable formats. Also learn to implement agentic memory to save state for reasoning and debugging, and see how human-in-the-loop input can guide agents at key junctures. You'll build an agent from scratch, then reconstruct it with LangGraph to thoroughly understand the framework. Finally, you'll build a sophisticated essay-writing agent that incorporates all the learnings from the course. Sign up here!

🔥 Our latest LangChain Academy course – Deep Research with LangGraph – is now live! 🔥 Deep research agents are taking off – from major AI labs to companies building their own. Research is inherently open-ended. You can't always predict whether a question needs broad exploration or deep analysis. Agents excel here because they adapt on the fly, using each finding to decide where to dig next. Building these systems ourselves and with customers, we've learned that structure matters. The best research agents scope problems with users first. Then, they coordinate multiple specialists instead of overwhelming one generalist. LangGraph is built for these types of long-running, multi-agent workflows. Its persistence layer tracks progress across agents. LangSmith gives you the observability and evaluation tools you need to track and improve performance. In this course, you'll build and evaluate: - A user scoping agent to define research parameters - A multi-agent research team with supervisor - And add tool integration via MCP Enroll for free ➡️

LangChain's CEO says they built their gateway a year too late, and it's still costing them. I sat down with Harrison Chase, Co-Founder & CEO of LangChain, to talk about what's changed since LangChain started as a side project in 2022, why sub-agents rarely work the way people expect, and why LangChain now runs its own hiring, content, and coding work through internal agents in Slack. 00:00 Why "I use agents for everything" is a red flag in an interview 01:21 How LangChain started as a fall 2022 side project 05:18 From LangSmith to LangGraph: rebuilding as the ground kept shifting 09:06 The gateway LangChain built a year too late 13:23 Code mode: why agents writing code beats human-style tools 19:04 Should the agent run inside the sandbox, or call it as a tool? 28:31 The agent identity problem: whose credentials does it use? 45:43 Running LangChain's own GTM, content, and coding agents in Slack 48:34 The AI slop problem, and why they built a Slack emoji for it The full pod is also available on YouTube, Apple Podcasts, or Spotify.
