The wait is finally over — OpenAI officially announced the full rollout of GPT-5.2 on December 11, 2025! Rumors had suggested OpenAI would release it on December 9, but the actual announcement was confirmed via the official Twitter/X account at 2:00 AM on December 12, pushing it out to users worldwide. This move was a direct response to the aggressive launch of Google's Gemini 3 Pro, and OpenAI CEO Sam Altman even issued an internal "code red" order to accelerate model iteration.
Discussion, leaks, and benchmark data about GPT-5.2 have been pouring in, and although there were fears it would be delayed, OpenAI simply went straight for the throat!
GPT-5.2 release announcement
OpenAI officially announced: the GPT-5.2 model family is fully live!
This time, they rolled out three versions at once: GPT-5.2 Instant, GPT-5.2 Thinking, and GPT-5.2 Pro.
It directly crushes Claude Opus 4.5 and Gemini 3 Pro, establishing a generation-level lead on professional knowledge work benchmarks! If you haven't seen the update in ChatGPT this morning, don't worry — this is a gradual gray-scale rollout, and paying users get priority.
GPT-5.2 Benchmarks: Topping the Leaderboards, with a Perfect AIME 2025 Score + Expert-Level GDPval of 70.9%
OpenAI claims GPT-5.2 is the most capable model series yet for professional knowledge work:
We are introducing GPT‑5.2, the most capable model series yet for professional knowledge work.
It topped the charts across every metric! Here are the key numbers — GPT-5.2 Thinking wins on nearly all benchmarks:
- SWE-Bench Pro (software engineering): 55.6%, far ahead of Claude Opus 4.5's 52.0% and Gemini 3 Pro's 43.3%.
- GPQA Diamond (science questions): 92.4%, a significant jump from GPT-5.1 Thinking's 88.1%.
- AIME 2025 (competitive math): 100% perfect score! Claude Opus 4.5 managed only 92.8%, and Gemini 3 Pro 95.0%.
- ARC-AGI-2 (abstract reasoning): 52.9%, while Claude Opus 4.5 scored only 37.6% and Gemini 3 Pro 31.1%.
- FrontierMath (advanced math, Tier 1-3): 40.3%, with Gemini 3 Pro at just 37.6%.
These numbers prove: GPT-5.2 Thinking has opened up a generation-level gap in reasoning ability.
GPT-5.2 benchmark leaderboard comparison
GPT-5.2 has gone absolutely ballistic this time! 🤯 It's grinding Gemini 3 Pro and Claude Opus 4.5 into the ground. Two jaw-dropping numbers:
1️⃣ AIME 2025 hits a perfect 100 (is this even an AI anymore? insert confused face meme).
2️⃣ GDPval soars to 70.9%! The previous top score was only in the 50s, and GPT-5.1 was just over 30 — this is a total different-dimension attack. Put GPT-5.2 Thinking in a head-to-head with professional experts and it wins over 70% of the time, while GPT-5 Thinking only won 38.8%.
