# OpenAI Transforms Responses API into Full Agent Runtime with Computer Environment

OpenAI has announced a significant upgrade to its Responses API, evolving it from a simple model interface into a complete agent runtime system. The enhancement equips the API with an actual computer environment for executing tasks.

The new system combines three key components: the Responses API, a shell tool for command execution, and hosted containers that provide secure, isolated environments. This infrastructure allows AI agents to maintain files, use tools, and preserve state across interactions—capabilities that were previously difficult to implement at scale.

This development marks an important shift in how developers can deploy AI systems. Rather than just getting text responses from a language model, developers can now build agents that interact with actual computing resources, run commands, and manage persistent data. The containerized approach ensures these operations remain secure and can scale to handle multiple users simultaneously.

For developers, this means less infrastructure work. Instead of building custom execution environments
