https://openai.com/index/introducing-upgrades-to-codex/
OpenAI has unified Codex into a single ecosystem. Access to the updated tool is included in ChatGPT Plus, Pro, Business, Edu, and Enterprise subscriptions. It cannot be used for free.

Codex is now available in the terminal (Codex CLI), as The Codex IDE extension, on the web (Codex cloud), on GitHub, and in the ChatGPT mobile app. There is also an option to switch to the GPT-5-Codex model.

The new version of the GPT-5 model - GPT-5-Codex is specially optimized for independently performing complex and long tasks (tested for 7 hours), such as creating projects from scratch, refactoring, and bug fixing. Special attention is paid to code review.

People are debating whether Codex CLI is finally better than Claude Code. It seems GPT-5 still follows instructions better and writes clearer and simpler code.
