1. LangChain Opens Managed Deep Agents in Public Beta

LangChain. LangChain moved its managed Deep Agents offering into public beta, giving developers a hosted way to run the long-horizon agent pattern without standing up and operating the infrastructure themselves. Deep Agents is LangChain’s framework for agents that plan, spawn subagents, and work through multi-step tasks over extended runs, and the managed tier handles the execution environment behind it. The beta lowers the barrier for teams that want the pattern in production but do not want to own the orchestration and scaling. Source
