What is OpenAI Codex?
Codex is OpenAI’s agentic coding product line built to complete multi-step engineering tasks—from refactors to migrations—using frontier coding models tied to ChatGPT accounts.
It competes directly with Cursor-style agents for teams that want OpenAI-managed cloud workspaces and parallel agent runs. Policy teams should still map data retention, export controls, and secret handling before wide rollout.
