alt Hacker NewsLooks like they've begun censoring posts at r/Codex and not allowing complaint threads so here is my honest take:
- It is faster which is appreciated but not as fast as Opus 4.5
- I see no changes, very little noticeable improvements over 5.1
- I do not see any value in exchange for +40% in token costs
All in all I can't help but feel that OpenAI is facing an existential crisis. Gemini 3 even when its used from AI Studio offers close to ChatGPT Pro performance for free. Anthropic's Claude Code $100/month is tough to beat. I am using Codex with the $40 credits but there's been a silent increase in token costs and usage limitations.

I’m curious about if the model has gotten more consistent throughout the full context window? It’s something that OpenAI touted in the release, and I’m curious if it will make a difference for long running tasks or big code reviews.
The speed bump is nice, but speed alone isn't a compelling upgrade if the qualitative difference isn't obvious in day-to-day use
5.2 is performing worse in technical reading comprehension for information and logic dense puzzles. It's way more confidently wrong and stubborn about understanding definitions of words.
Did you notice much improvement going from Gemini 2.5 to 3? I didn't
I just think they're all struggling to provide real world improvements
