Interrupt 26: The Agent Conference by LangChain
LangChain launched SmithDB and LangSmith Engine to power a full Agent Development Lifecycle platform.
“Today, we launched SmithDB as a foundational database to power all of this, and we built LangSmith Engine as an agent that sits on top and helps you spin this flywheel faster and faster.”
At Interrupt 26, LangChain announced SmithDB—a foundational database—and LangSmith Engine, an agent layer built on top, together forming what LangChain calls a complete Agent Development Lifecycle platform. The launch marks LangChain's strategic shift from a framework provider to a full-stack platform and infrastructure play. This matters because it signals the agent tooling market is consolidating around lifecycle management, with trace-centric observability at the core.
