Positive feedback for Codex

I just wanted to leave some genuine positive feedback about Codex.

I’ve been using Codex based on GPT-5.4, and I’m honestly impressed. It feels like a very strong coding tool, especially for real project work and not just small isolated tasks. In my experience, it handles complex development work extremely well, and overall it has felt stronger and more reliable than Claude Code.

One thing I especially appreciate is the usage limit experience. Thank you for not making it feel overly restrictive. With Codex, it actually feels possible to sit down and work for hours in a serious way without constantly feeling blocked by limits. That makes a huge difference when you are trying to build something real and stay in flow.

GPT-5.4 Codex genuinely feels powerful, practical, and enjoyable to use. Thank you to the OpenAI team for building this and for making it accessible enough to be used like a real development tool.

Have you seen

We’re shifting from single-turn assistants to long-running agents that handle real knowledge work: reading large datasets, updating files, and writing apps.


Symphony monitors a Linear board for work and spawns agents to handle the tasks. The agents complete the tasks and provide proof of work: CI status, PR review feedback, complexity analysis, and walkthrough videos. When accepted, the agents land the PR safely. Engineers do not need to supervise Codex; they can manage the work at a higher level.
