Vasek Mlejnsky(@mlejva):OpenAI's new Agents API is a hosted Codex runtime that can connect to sandboxes like E2B. @OpenAI manages the model, harness, and agent sessions, while code executes on an isolated @e2b machine with its own filesystem and preinstalled tools. We built an agent workbench where each chat runs on its own machine. It starts from a custom template, auto-pauses between turns, forks to try another approach from the same starting point, and can even act on videos inside the sandbox. Thanks @ondrej_sh for the workbench demo! Try it: e2b sbx create openai-agents-api-python-sdk Build on top of the workbench: https://t.co/mRWhQ7UMbq Docs:

Go from idea to a working agent faster with the Agents API. Build and run cloud agents with the Codex harness, fully managed by OpenAI. We handle orchestration, long-running sessions, and context management. You focus on what makes your agent unique. Available in public beta.
