@clay @jeffbarg Watch more sessions from Interrupt. interrupt.langchain.com/recordings
At Interrupt, @Clay's Head of AI @jeffbarg shared insights from running 350m GTM agents a month. ✅ Caching can cut LLM costs up to 70% ✅ Bounding tool calls often improves quality, not just cost ✅ Fairness queues matter once you have real multi-tenant load Worth 12 minutes if you're building agents for production. youtu.be/LmQtSORYPfw
One LangChain model object gives you access the whole @OpenRouter catalog for Deep Agents. Route by throughput, latency, or price. Filter providers. Enforce ZDR/no data collection. Select fallback models. When OpenRouter adds a provider or model, just pass the new slug. docs.langchain.com/oss/python/int…
Access all the providers for GLM 5.2 in one spot. Including one serving at over 125 TPS: openrouter.ai/z-ai/glm-5.2
🗣️Voice traces in LangSmith just got an update! Now, LangSmith has an audio player that runs inline with spans. No new tabs necessary. See what was being played when a particular span was active, or see what span was active when a particular piece of audio was being played.

You can turn an existing LangGraph agent into a fully functional voice agent with @pipecat_ai. This 17-minute walkthrough shows you exactly how to do it.

That's why we built LangSmith Engine, an agent built to improve your agent. Engine identifies issues from traces, clusters patterns, drafts fixes, and proposes evals to prevent regressions. Connect your tracing project + start improving your agent today: langchain.com/langsmith/engi…
Most teams building today have traces, what they don't have is a system for continuously improving their agents. The teams that do use an agent development lifecycle: build, test, deploy, and monitor. The problem with this lifecycle? It scales at the speed of their engineers.

An awesome opportunity to learn about the Agent Development Cycle with @hwchase17 ⤵️
One thing we’ve seen pretty consistently: shipping the first version is only a small part of the work A key part of building reliable agents is having a repeatable lifecycle for improving them over time Here’s what that looks like: 1/ Build. Start with the agent, tools,
LangSmith Fleet has two types of agents: General Purpose Chat and Specialized Agents. A breakdown on why this is a deliberate choice and when to use each. langchain.com/blog/why-fleet…
🧠Self-Harness: Harnesses that improve themselves New paper on agents shaping their own harnesses to improve over time. Not from LangChain, but builds on top of DeepAgents! Three key steps: 1/ Weakness mining: find failure modes from traces 2/ Harness proposal: suggest changes to the harness 3/ Proposal validation: does regression testing on proposals and then accepts Paper: arxiv.org/pdf/2606.09498 Builds on top of DeepAgents: github.com/langchain-ai/d…
Speaking of "this is your opportunity to try GLM 5.2" 👀
Ready to see how you can meet the core technical requirements of the EU AI Act with LangSmith? langchain.com/blog/langsmith…
When the EU AI Act goes into effect, compliance will become an ongoing measurement obligation. With LangSmith, you can turn tracing into compliance evidence. Run our customizable evaluators on production traffic, and score on the EU AI Act’s requirements, including bias, hallucination, toxicity, accuracy, and adversarial inputs.
interesting point here: loops amplify behavior, making them a double edged sword but we know loops are the future, so how do we avoid amplifying bad patterns? you need an *engaged* human in the (stacked) loop(s) your agent needs to learn your taste! x.com/sydneyrunkle/s…
