Interrupt NYC: Opening Keynote

This talk announces Managed Deep Agents, an evolution of the Deep Agents harness, introducing authentication primitives, user-level memory, and integrated web search. It also details the LangSmith platform's enhancements: the LangSmith LLM Gateway for routing model calls through decision models like Jev, LangSmith Trajectories for faster agent debugging, LangSmith Fine-Tuning with the smithtune CLI for optimizing trajectories into models, and LangSmith Custom Apps for building UIs on LangSmith data. LangSmith Engine v2 is introduced with advanced red teaming capabilities and automated self-testing of fixes, building upon its extensive trace analysis.
