The EU AI Act is the first comprehensive regulation for AI systems, and it’s right around the corner.
With the clock running down, we took a deeper look at what these requirements mean for your agents at the Article level, and how LangSmith @LangChain_OSS directly address them.

LangChain Community Spotlight: Distributed LangGraph Architecture with RemoteGraph 🔗
Production-ready example for distributed LangGraph apps with HTTP-invoked subgraphs. Key insight: RemoteGraph returns full state, not deltas—parents handle reducers.

Only three weeks until Interrupt!
As a LangChain partner, we help teams get agents integrated, observed, and running reliably inside the systems they already have.
If you're building and need agent expertise, grab time with us at Interrupt. See you there!

Spent last week at #O11yDayNYC alongside our partners at Honeycomb.
Much of the conversation focused on how observability evolves as systems become more complex. Exactly the work we’ve been leaning into together.
Big thanks to the Honeycomb team for bringing everyone together for such a great event.

Our newest use case is up! Streaming agent state with LangGraph.
If your agent takes ~9 seconds to run a workflow, don’t make users stare at a blank screen.
Stream node updates, tool calls, and LLM tokens to the UI while it runs.

If you have a good answer you get an interview
9 Dec 2025
I have an interview question I was told is too hard for the Agent Engineer position. How would you solve it?
If you do well you can skip the first two interviews.
Client has asked us to create a RAG for discovery documents for trial. Documents are transcripts from depositions, emails, and SMS.
The client would like the AI to answer the question "has X person ever contradicted themselves, show me where?"
Explain how you'd create a agentic RAG that can solve this problem.

LangChain systems break.
The agent blames RAG.
RAG blames the vector store.
And no one knows what actually failed.

We helped Hamlet launch Speaker Search, an LLM-powered tool that makes civic data easier to navigate.
Built with @langchain, LangSmith, and custom evals. Over 90% accuracy. Live in under 3 months.

Agents without structure will fail in prod.
LangGraph is the fix.
The agent works once in dev, maybe even passes a few tests, then breaks the second it hits something unexpected.
See how we build it: focused.io/langchain
