LangSmith revamps tracing UI to visualize Jev-style decision LLM calls in agents
hwchase17 · x · 2026-09-23
- LangChain shipped an improved tracing view in LangSmith to clearly display Jev-like calls (state, questions, choices, output).
- The rationale: agents are becoming complex systems of many LLM calls, and many of those calls will be Jev-style decision models, so observability tooling needs to render them differently.
- The update was announced live during a LangChain x Jev webinar with 500 attendees.
