About LangChain
LangSmith is hardening as the agent observability and ops layer; Fleet rebrands the builder.
LangChain's recent cadence is concentrated on LangSmith — pinned baseline experiments for evals, unified cost tracking across agent workflows, scheduled Insights Agent reports, customizable trace previews, and pairwise annotation queues. The Agent Builder was rebranded to LangSmith Fleet and got chat-style interaction, file uploads, and a tool registry. Deep Agents v0.4 added pluggable sandboxes and switched to OpenAI's Responses API as default.
