Overview
- The SDK update, which OpenAI announced Wednesday, is available to all API customers and uses standard token and tool pricing.
- The architecture separates the agent harness from the compute so tool calls run unprivileged and company secrets remain outside the sandbox.
- A new model-native harness lets agents handle files, run approved tools, and manage memory inside a defined workspace suited to long tasks.
- Teams can bring their own containers or use Blaxel, Cloudflare, Daytona, E2B, Modal, Runloop, or Vercel, and mount storage from AWS S3, Google Cloud Storage, Azure Blob, or Cloudflare R2.
- The release starts with Python, TypeScript support is planned, and OpenAI is adding durability features like snapshot and rehydration plus options such as code mode and subagents.
