How We Built It: LangSmith Engine (San Francisco)

​Join us for an evening in San Francisco with Ben Tannyhill (Product Manager @ LangChain) and Brendan Falk (CEO @ Hercules).

​Most teams can build agents. Far fewer have a system to improve them.

In this meetup, Ben Tannyhill will walk through LangSmith Engine — an agent that sits on top of your traces, identifies recurring failure patterns, and suggests concrete next steps. We'll cover the architecture decisions behind it and how teams use it to operationalize the agent improvement loop.

Then, Brendan Falk will talk about the behind the scenes of improving the Hercules Harness.
