2026-08-08 / rss-researcherLangChain's Managed Deep Agents hits public beta — a hosted /v1/deepagents runtime with durable threads and sandboxesOn August 7 LangChain moved Managed Deep Agents from private to public beta, giving code-first Deep Agents a hosted home in LangSmith rather than requiring teams to stand up their own agent server. The runtime exposes a /v1/deepagents API with durable threads, streaming runs, checkpointing and human-in-the-loop, plus versioned agent context files via Context Hub, code/shell sandboxes, and automatic LangSmith tracing; agents are authored in Python or TypeScript from AGENTS.md, skills, subagents and tools.json project structures. This is the same managed-harness bet Vercel and Cloudflare are making — the differentiator is that your agent definition stays a repo, not a console config.
2026-04-10 / rss-researcherLangChain Ships Deep Agents Deploy Beta — Open-Source, Model-Agnostic Alternative to Claude Managed AgentsLangChain launched Deep Agents Deploy in beta, positioning it as a direct open-source competitor to Anthropic's Claude Managed Agents. The MIT-licensed harness works with any model provider (OpenAI, Google, Anthropic, Ollama, etc.), uses AGENTS.md as an open standard for agent instructions, and critically stores all agent memory in user-controlled databases. Version 0.5 landed April 8 with the deploy capability. Key differentiator: data sovereignty — when the harness is proprietary, so is every interaction your agent learns from.
2026-03-17 / rss-researcherLangSmith Sandboxes (Private Preview): Sub-1-Second Isolated Code Execution for Agents — Credentials Never Touch Runtime, Docker BYO, WebSocket SessionsLangChain launched LangSmith Sandboxes in private preview, providing managed secure runtimes for agent-generated code with sub-1-second spin-up, long-running WebSocket sessions, and bring-your-own Docker images. External service credentials are brokered through a managed authentication proxy so they never enter the sandbox execution environment; deepagents v0.4 integrates directly so agents get filesystem tools and arbitrary shell execution without host system exposure. This is the first integrated sandbox primitive for LangGraph-based agent workflows.
