Private preview scope
Managed Deep Agents is available on LangSmith Cloud in the US region only during private preview. Self-hosted and Hybrid deployments are not supported, and EU and other regions will follow general availability. The API also does not mirror every LangSmith Deployment endpoint in private preview. Endpoint groups such as integrations, auth, triggers, skills, and sandboxes are not mirrored yet. For operational notes — supported models, thread retention, rate limits, SDK availability, and support channels during preview — see Limits and notes in the deploy guide.Connect these docs to Claude, VSCode, and more via MCP for real-time answers.
