> it’s better at creating spreadsheets

I have a bad feeling about this.

Excited to try this. I’ve found Gemini excellent recently and amazing at coding. But I still feel somehow like ChatGPT understands more. Even though it’s not quite as good at coding - and nowhere at as fast. It is much less likely anti spontaneously forget something. Gemini’s is part unbelievably amazing and part amnesia patient. I still kinda trust ChatGPT more.

It's dog-doo-doo. I put in my algebraic geometry final review (100's of thousands of tokens) and Gemini instantly found all the propositions, theorems, and problems that I needed in a neat list (in about 5 seconds), meanwhile ChatGPT 5.2 Thinking took 10mins before timing out and not even completing the request.

However, the model card for GPT 5.2 looks amazing, wish I could actually see that performance in action!

So, does 5.2 still have a knowledge cutoff date of June 2024, or have they managed to complete another full pre-training run?

It seems like they fixed the most obvious issue with the last release, where codex would just refuse to do its job... if it seemed difficult or context usage was getting above 60% or so. Good job on the post-training improvements.

The benchmark changes are incredible, but I have yet to notice a difference in my codebases as of yet.

>GPT‑5.2 sets a new state of the art across many benchmarks, including GDPval, where it outperforms industry professionals at well-specified knowledge work tasks spanning 44 occupations.

We built a benchmark tool that says our newest model outperforms everyone else. Trust me bro.

The ARC AGI 2 bump to 52.9% is huge. Shockingly GPT 5.2 Pro does not add too much more (54.2%) for the increase cost.
