Introducing Managed Deep Agents

Managed Deep Agents, introduced in private beta, offers an API-first hosted runtime for creating and operating deep agents, allowing developers to focus on agent behavior rather than infrastructure. Built on the open-source Deep Agents harness, this solution provides a durable home for agents in LangSmith, facilitating programmatic creation, management, and execution of agents without the need for custom server setups. The system supports durable threads, streaming runs, checkpointing, human-in-the-loop workflows, and sandbox-backed execution, enabling agents to maintain context and improve over time. LangSmith's API enables developers to integrate tools and sandboxes, trace runs, debug behavior, and observe improvements, providing deep agents with the runtime necessary for long-term, tool-using, and context-preserving operations. This managed approach is suitable for various applications, including support, research, coding, data analysis, and internal operations agents, which require robust, durable execution capabilities to function effectively over extended periods.
