OpenAI gives AI agents a safe sandbox to run code
OpenAI just updated its Agents SDK with a model-native harness and built-in sandbox execution. Developers can now run agents in isolated workspaces powered by providers like E2B, Modal, and Vercel, allowing them to inspect files, edit code, and run shell commands safely. The harness also snapshots state so long-running tasks survive crashes. It is rolling out first for Python.
