OpenAI opens Agents API public beta to all developers

A post sharing OpenAI’s announcement says the Agents API gives developers the same underlying agent framework used by Codex. It says OpenAI manages orchestration, long sessions, and context compression and recovery, while developers choose capabilities and sandbox environments. Those environments can be OpenAI-hosted, self-managed or connected to providers such as E2B, Modal and Cloudflare. The post also lists support for tools, sub-agents and durable sessions.
