Honestly, the new features are not the main issue. The limits are.
A coding assistant is only useful if it can survive normal iterative development. Right now, the limit model feels too restrictive for real work. It breaks momentum, discourages experimentation, and turns ordinary coding flow into quota management.
That makes all the “new Codex for almost everything” messaging hard to take seriously. If using the product normally burns through limits too fast, then it is not built for “almost everything.” It is built for small, cautious usage bursts.
OpenAI needs to fix the limit system first. Otherwise the product keeps improving on paper while becoming less usable in practice.
