Was just about to write the same thing. 5.2 Pro is an actual paradigm shift for me, in terms of working for long periods of time on complex quantitative tasks. Best in class, and by a long shot.
OK, I think GPT 5.2 Pro is actually a step change in usefulness for my applications (algebraic geometry/number theory research).

390x cost reduction in a year!
A year ago, we verified a preview of an unreleased version of @OpenAI o3 (High) that scored 88% on ARC-AGI-1 at est. $4.5k/task Today, we’ve verified a new GPT-5.2 Pro (X-High) SOTA score of 90.5% at $11.64/task This represents a ~390X efficiency improvement in one year

Even without the ability to do new things like output polished files, GPT-5.2 feels like the biggest upgrade we've had in a long time. Curious to hear what you think!
