same sentiments with an article author - gpt5 looks like a cost-cut initiative.

my personal feeling gpt5-thinking is much faster but doesnt produce the same quality results as o3 which were capable to scan through the code base dump with file names and make correct calls

dont feel any changes with https://chatgpt.com/codex/

my best experience was to use o3 for task analysis, copy paste the result in https://chatgpt.com/codex/, work outside and vibe code from mobile
