Anthropic Built It. OpenAI and LangChain Just Responded. You Now Have A Decision To Make.

Three of the biggest players in AI all made moves in the agent space over the last seven days. Anthropic launched Claude Managed Agents, a fully cloud-hosted agent platform. The very next day, LangChain responded with Deep Agents Deploy, explicitly positioned as the open alternative. And then OpenAI shipped the next evolution of the Agents SDK.

The problem is none of these announcements make sense in isolation. Each one is solving a different version of the same problem, at a different point on the build-to-buy spectrum.
