OpenAI Launches Agents API in Public Beta for All Developers
OpenAI has released its Agents API into public beta for all developers. The tool is built upon the Codex framework and manages model calls, context, and the execution of AI agents in the cloud.

What happened?
OpenAI has opened its Agents API to a public beta for all developers. The API is based on the Codex framework and enables the construction and execution of cloud-based AI agents. OpenAI handles model calls, tool usage, task orchestration, long-lived sessions, and context storage, while the developer defines the agent's capabilities.

Why it matters
By providing readymade infrastructure for agents, OpenAI simplifies the development of applications capable of performing multi-step tasks and executing code in secure sandboxes. Developers gain control over resources such as CPU, GPU, memory, and key storage, and can choose between OpenAI's fully managed environment or third-party sandboxes.
Who is affected?
The service is primarily aimed at software developers and enterprises looking to build autonomous AI agents without needing to construct their own infrastructure for session management or context. Both individual developers and enterprise customers requiring custom execution in their own cloud environments (VPC) are the target audience.
Impact on the EU
The Agents API is available to developers globally via OpenAI's platform, including in the EU. Companies building on the API within the EU must, however, account for data residency and accountability regarding the handling of personal data in cloud environments.
What else you should know
Among the initial integration partners for sandbox environments are companies such as E2B, Cloudflare, DigitalOcean, Daytona, and Blaxel. The system is built on the same infrastructure that powers OpenAI's internal code and agent management (Codex), providing developers with access to proven tools for complex agent workflows.
