I've benchmarked it on the Extended NYT Connections benchmark (https://github.com/lechmazur/nyt-connections/):
The high-reasoning version of GPT-5.2 improves on GPT-5.1: 69.9 → 77.9.
The medium-reasoning version also improves: 62.7 → 72.1.
The no-reasoning version also improves: 22.1 → 27.5.
Gemini 3 Pro and Grok 4.1 Fast Reasoning still score higher.
I would like to see a cost per percent or so row. I feel like grok would beat them all
Here's someone else testing models on a daily logic puzzle (Clues by Sam): https://www.nicksypteras.com/blog/cbs-benchmark.html GPT 5 Pro was the winner already before in that test.
Gemini 3 Pro Preview gets 96.8% on the same benchmark? That's impressive
