GPT-5 Has to be The Worst Model I Have Ever Used For Coding

It is absolutely horrendous. Let me list out the problems

1. Thinks for a million years and gives very very comprehensive outputs as to what it wants to do and how it will do it. Good as a planner, maybe, but:

2. Ends up doing none of it and creating such pathetic simple base code that it does not even satisfy the basic prompt u had sent to it before to plan.

3. When asked to implement features in existing code it does it so poorly, barely outputs anything meaningful, does not integrate the features well within the existing codebase, and a lot of times (majority) thinks it has implemented boatloads of changes but has implemented barely any

4. IT OUTRIGHT LIES ABOUT THINGS

Either the model is very poor or it has to be the worst cursor integration I have seen in my time and I have used the crap out of cursor. Even auto seems to perform better for me than gpt5 and that I feel is a shame.
