From model to agent: Equipping the Responses API with a computer environment

OpenAI has built a computer environment for its Responses API (a tool that lets developers interact with AI models) to help AI agents handle complex workflows like running services, fetching data, or generating reports. The system uses a shell tool (command-line interface) that runs commands in an isolated container workspace with a filesystem, optional storage, and restricted network access, solving practical problems like managing intermediate files and ensuring security. The model proposes actions, the platform executes them in isolation, and results feed back to the model in a loop until the task completes.
