LangChain: Engineer reliable agents

We're launching LangChain 1.0 and LangGraph 1.0 — and announcing our $125M Series B. Building reliable agents has traditionally been hard. What started as frameworks for LLM applications has evolved into something bigger: the platform for agent engineering. We're launching some massive updates, including: ✅ LangChain 1.0: completely revamped with middleware for flexibility ✅ LangGraph 1.0: production-ready runtime with durable state ✅ New Insights Agent: aggregate usage patterns on production data ✅ No-code builder: text-to-agent creation, now in private preview Trusted by Replit, Clay, Vanta, Cloudflare, Rippling, Cisco, Workday, and more.
