The 10 background workflows OpenAI’s own team runs while they sleep. The 4-step build pattern. The 30-day rollout that turns Codex from “cool demo” into “I forgot it was running.”

Andreessen said it. Amodei said it. Hassabis said it. Three frontier-lab CEOs converged on the same thesis in the same quarter, and OpenAI just shipped the most operational version to date.
Codex. Autonomous coding agent. Background workers. Scheduled tasks. Long-running jobs running in sandboxed environments while you sleep, shipping pull requests, drafting reports, qualifying leads, waking you up to merged work.
9 of 10 builders are still using ChatGPT like a smarter search bar.
Most people ask, get an answer, copy it out, move on. A workflow runs on a trigger, uses tools to act, and hands you a finished result. The chat answers.
