Self-Improving Agents: Systems Engineering and Evaluation Infrastructure
By
–
Self-improving agents isn’t a single algorithm – it’s a systems engineering problem involving: – eval data curation + maintenance – experiment design to battle overfitting – an update algorithm – human review during the process & especially before prod we share practical learnings + a local research scaffold to autonomously hill-climb harness centered around evals our goal is to give everyone the tooling and infra to measure and iteratively their improve agents. Evals are training data for agents which fuels this loop let's build the future of well-designed, self-improving systems 🚀 Viv (@Vtrivedy10) x.com/i/article/204172946391… — https://nitter.net/Vtrivedy10/status/2041927488918413589#m

At Interrupt, Senior Software Engineers Tracy He and Shang Liu will walk through how they built it: the agent architecture, the tool-calling patterns that power it, and how they keep the system observable in production with LangSmith. Catch Tracy and Shang’s talk along with all the others at Interrupt, the Agent Conference by LangChain. May 13-14 in San Francisco. Get tickets here 👉 interrupt.langchain.com

I love these almost as much as i love using langsmith https://t.co/WJVg1aFPsE

The themes all point to the same problem: you don't know what your agents will do until you actually run them. What works in demos can break in the real world. Without tracing and evals, you're just guessing at why. Track what your agent actually does. Optimize and fix your agents. Then measure whether your fixes work. That loop is how agents get better, and LangSmith is built to power that workflow. If you spot one around, send it our way! — https://nitter.net/hwchase17/status/2041546634895757684#m
