Openai has just launched GPT-5-Codex. The problem is that I already had three more calls exactly the same.
Why is it important. This accumulation of identical names converts the choice of tools into a headache. Each “codex” does something different, but from the outside it seems the same multiplied product.
In detail. The “Codex” family has these members:
- GPT-5-Codexthe newcomer. A model that program for hours without supervision. Change speed according to complexity: fast for simple, slow and meticulous tasks for large projects.
- Codex Cloudthe veteran. It works as a remote programmer. You send you work and return with code finished after a few minutes of solo work.
- Codex Clithe local assistant. A terminal utility that helps you from your computer. Competes directly with tools such as Claude Code.
- Codex (2021). The grandfather of the family. Fed the first versions of Github co -ilotbut it is no longer operational.
Between the lines. Openai is trying to fix the linguistic mess. Now writes “GPT-5-codex” with scripts to differentiate it, implicitly admitting that the situation has been lacking.
The new model reduces the use of resources into basic tasks by 94%, but multiplies by two the processing time in complex projects. Internally it already supervises more code than human reviewers.
The background. Openai seems to have developed these tools without central coordination, something similar to what ended up with the pre- models selectorGPT-5. Each team chose “Codex” independently.
And now what. The company prepares access via API for its latest model. Meanwhile, it is time to assume that “Codex” is more a business philosophy than a specific product.
The lesson: even the most advanced companies can stumble with something as basic as putting names to their creations.
