GPT-5.4 in Codex Feels Degraded

You can start trouble shooting right in chatgpt. There are some very smart people here on the forum and plenty of documentation and many resources to help you understand codex better as well as guidance on how to get it to run smoothly. Generally, we don’t waste credits on prompts to codex for simple ‘hellos’. It’s a coding tool, and it can be expensive if you start chatting with it like it’s regular chatgpt. There are a lot of questions that someone who might offer you guidance would need to know… like the size of your repo… an example of a task… among other things. The first place I would start is start talking to regular chatgpt about the concern you have with codex, ask it to give you an audit prompt to determine why you’re experiencing what you are experiencing… Chances are high you can get your issue sorted out that way, much quicker than what anyone here could possibly do for you with such a short and very vague description of your specific issue. I wish you the best!
