OpenAI expands Codex into a more comprehensive development assistant

OpenAI is expanding Codex from a code-generation tool into a broader development agent.

Codex can now control computers, manage tasks across linked tools, review files and terminals, work with images, and handle scheduled work.

The rollout is phased, and some features are limited by platform and region.

The update brings AI coding tools closer to end-to-end developer agents and could intensify competition in the market.
