The wait is finally over — OpenAI officially announced on December 11, 2025 that GPT-5.2 is fully rolling out! Rumors earlier said OpenAI would release it on December 9, but it was actually confirmed via the official X account at 2 a.m. on December 12 and pushed to users worldwide. This move is a direct response to the strong arrival of Google's Gemini 3 Pro, and OpenAI CEO Sam Altman even issued an internal "code red" directive to accelerate model iteration.
The discussion, leaks and benchmark data surrounding GPT-5.2 had been endless, and many worried it would be "difficult to deliver" — but OpenAI came out swinging!
GPT-5.2 release announcement
OpenAI officially announced: the GPT-5.2 model series is fully live!
This time they launched 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, achieving a generation-level lead on professional knowledge work benchmarks! If you haven't seen the update in ChatGPT yet this morning, don't worry — this is a gradual, phased rollout, with paying users getting priority.
GPT-5.2 Benchmarks: Topping the Charts, Perfect AIME 2025 + Expert-Level 70.9% GDPval
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.
Scores across the board are topping the charts! Let's look at the key numbers — GPT-5.2 Thinking wins on nearly every benchmark:
- 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 (competition math): a perfect 100%! Claude Opus 4.5 only manages 92.8%, and Gemini 3 Pro 95.0%.
- ARC-AGI-2 (abstract reasoning): 52.9%, while Claude Opus 4.5 scores just 37.6% and Gemini 3 Pro 31.1%.
- FrontierMath (advanced math, Tier 1-3): 40.3%, with Gemini 3 Pro at only 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 is absolutely crushing it this time! 🤯 It is wiping the floor with both Gemini 3 Pro and Claude Opus 4.5. Two stunning numbers:
1️⃣ A perfect 100 on AIME 2025 (is this even AI? insert confused face).
2️⃣ GDPval has soared to 70.9%! The previous number one was only in the 50s, and GPT-5.1 managed just over 30 — this is a dimensionality-reduction strike. Put GPT-5.2 Thinking in a head-to-head with professionals and it wins more than seven out of ten times, while GPT-5 Thinking only reached 38.8%.

GPT-5.2's Three Versions Explained: How to Choose and Use? Full Coverage from Professional Work to Everyday Study
The GPT-5.2 versions have clear positioning, covering everything from daily use to high-end professional needs. Here are the core features and usage guide for each version to help you get started quickly:
GPT-5.2 Thinking: The Professional Work Powerhouse
- Core strength: State-of-the-art long-context reasoning (supports a 400,000-token window, capable of handling hundreds of documents).
- Upgrade highlights: Major improvements to table/Excel creation, analysis and formatting; initial enhancements to slides; more reliable code writing and debugging.
- How to use: Select the "Thinking" mode in ChatGPT and give it complex tasks such as "build an LBO model from this financial report and format an Excel sheet". Ideal for programmers, analysts and researchers.
- Use cases: Software engineering, data analysis, scientific research planning.
GPT-5.2 Instant: The First Choice for Daily Study and Work
- Core strength: Inherits GPT-5.1's warm conversational style with faster responses.
- Upgrade highlights: Clearer explanations (key information prioritized); more practical tutorials/guides; stronger technical writing and translation; more thoughtful study/career guidance.
- How to use: Switch to Instant directly in the free/Plus mode of ChatGPT and try "teach me Python basics in simple steps and provide practice exercises".
- Use cases: Writing, translation, student homework, workplace onboarding guidance.
GPT-5.2 Pro: The Smartest, Most Reliable Top-Tier Version
- Core strength: Strongest performance in complex areas like coding, with the highest accuracy.
- Upgrade highlights: Accelerates scientific research; fewer hallucinations, more stable long-context understanding.
- How to use: Pro users enable it in the ChatGPT Pro plan, e.g. "analyze this molecular structure image and generate PySCF simulation code".
- Use cases: Advanced programming, scientific experiments, investment modeling.
Tip: In ChatGPT, switch versions via the model selector; API developers get access immediately (pricing: $1.75/million input tokens for the standard version, up 40% from GPT-5.1). GPT-5.1 will be kept as a Legacy Model for 3 months.
