OpenAI itself already offers several of those building blocks through products such as its Responses API, which developers could use to combine models with built-in capabilities including web search, file search and computer use, and its Agents SDK for defining and orchestrating agent workflows.
Agents API, which is currently in public beta, in contrast, can help developers design a custom agent in a single API call after they specify the task, model, tools, and the environment, the model provider wrote in a blog post.
For that execution environment, developers can choose to run agents in an OpenAI-managed sandbox, on their own infrastructure, or through supported sandbox providers, including Blaxel, Cloudflare, Daytona, DigitalOcean, E2B, Modal, Oracle, Runloop, and Vercel, it added.
