OpenAI drops Codex, an autonomous agent that codes in the cloud
OpenAI just launched Codex, a cloud-based software engineering agent powered by codex-1, a specialized version of o3. It operates inside isolated cloud sandboxes to write features, execute test suites, and open GitHub PRs across multiple tasks in parallel. Why it matters: Developers can now offload entire background engineering workflows asynchronously rather than babysitting real-time completions.
