After weeks of speculation, OpenAI has officially released GPT-5.2, and the update is far bigger than anyone expected. This is not just a small refinement — GPT-5.2 introduces the largest reasoning jump in the history of OpenAI’s 5-series models and marks the first time an OpenAI model has reached human-expert performance across real-world knowledge-work tasks.
Below is the complete breakdown of everything OpenAI revealed today: performance benchmarks, new capabilities, versions, pricing, release timeline, and why GPT-5.2 is being described internally as a “Code Red-level upgrade.”
GPT-5.2 is rolling out slowly — many users still can’t use it. GlobalGPT is already integrating the new model, and you’ll be able to access its full power for just 30% of the official price. No waiting. No restrictions.
If you want GPT-5.2 performance without the delay or the cost, GlobalGPT is your best alternative.
01｜GPT-5.2 Reaches Human-Expert Level on GDPval
OpenAI uses an internal benchmark called GDPval, designed to measure AI performance in realistic work tasks such as:
- making PPTs
- analyzing documents
- generating reports
- building spreadsheets
- complex writing and planning
On these tasks, GPT-5.2 has over a 70% chance of outperforming or matching human experts. By comparison, the previous GPT-5 Thinking scored 38.8%, Google’s Gemini 3 Pro reached 53.3%, and Anthropic’s Claude Opus 4.5 achieved 59.6%.
GPT-5.2 shattered previous records
| Model | GDPval Win / Tie Rate |
|---|---|
| GPT-5.2 Thinking | 70.9% |
| GPT-5.2 Pro | 74.1% |
| GPT-5 Thinking | 38.8% |
| Google Gemini 3 Pro | 53.3% |
| Claude Opus 4.5 | 59.6% |
OpenAI calls GPT-5.2:
“Our first model to reach human-expert level performance.”
This is a massive milestone — and one that changes what “AI productivity” means in practical, everyday use.
02｜ARC-AGI-2: A 3× Leap in Pure Reasoning Power
If GDPval tests “work ability,” the ARC-AGI-2 benchmark tests “intelligence.”
It measures abstract reasoning and can’t be solved through memorization or brute force.
Three weeks ago, Google stunned the AI world when Gemini 3 Pro hit 31.1%.
GPT-5.2 Thinking exploded past that:
| Model | ARC-AGI-2 Score |
|---|---|
| GPT-5.2 Thinking | 52.9% |
| GPT-5.2 Pro | 54.2% |
| GPT-5.1 Thinking | 17.6% |
A jump from 17.6% → 52.9% in a single version is unprecedented.
This is the largest reasoning improvement in the history of OpenAI.
And this is not a “major version” like GPT-6 — it’s labeled as a “minor update.”
OpenAI is clearly serious.
03｜Programming, Math, and Multimodal: Massive Improvements Everywhere
GPT-5.2 doesn’t just think better — it works betteracross every domain.
✔ Programming (SWE Bench Pro)
- 55.6% on SWE Bench Pro
- 80% on SWE Bench Verified
Four languages, harder problems, much higher reliability.
✔ Math
On AIME 2025 (a real U.S. math competition):
- GPT-5.2 Thinking scored 100% — a perfect score.
- It is the first AI model in history to achieve this without tools.
✔ Multimodal understanding
Error rates dropped by 50%, according to OpenAI.
- CharXiv Reasoning: 88.7%
- ScreenSpot Pro: 86.3%
GPT-5.2 is now significantly better at interpreting:
- graphs
- scientific charts
- UI screenshots
- technical documents
✔ Hallucinations
Reduced by 30%.
OpenAI still warns:
“GPT-5.2 isn’t perfect. For anything important, verify the answer.”
A rare, refreshing honesty.
04｜Three Versions of GPT-5.2 (All Available Today)
GPT-5.2 comes in three specialized versions:
🔥 GPT-5.2 Instant — Fastest
- Optimized for everyday chat
- Better clarity
- More natural responses
- Faster than 5.1
🧠 GPT-5.2 Thinking — Deep Reasoning
For tasks requiring actual structured thinking:
- coding
- math
- planning
- analysis
- document understanding
💎 GPT-5.2 Pro — Smartest, Slowest
- The highest-accuracy model OpenAI has ever built
- Ideal for research, complex reasoning, and enterprise workflows
Release
- Plus / Pro / Team / Enterprise: rolling out today
- Free & ChatGPT Go: available tomorrow
- GPT-5.1 becomes a “Legacy Model” and will be removed in 3 months
API Pricing
Input: $1.75 / million tokens
Output: $14 / million tokens~40% more expensive than GPT-5.1 — but more efficient overall.
05｜Internal Codename: “Garlic”
OpenAI teased the launch yesterday with photos of Sam Altman frying garlic in a kitchen.
Now we know why:
GPT-5.2’s internal codename is “Garlic.”
OpenAI’s application CEO confirmed:
- GPT-5.2 has been in development for months
- But Code Red helped push the entire company to refocus on core quality
- Non-essential projects were deprioritized
- OpenAI aims to lift “Code Red” in January
The AI competition is clearly the fiercest it has ever been.
Final Verdict: GPT-5.2 Is the Most Important 5-Series Update Yet
Compared with all previous 5.x versions, GPT-5.2 brings:
✔ Human-expert performance on real work tasks
✔ A historic leap in reasoning
✔ Perfect math scores
✔ Far better coding reliability
✔ Dramatically improved multimodal understanding
✔ Fewer hallucinations
✔ Three specialized versions for different needs
This is not GPT-6 — but for practical, everyday productivity, it might be even more impactful.
GPT-5.2 Thinking and Pro will change how people:
- analyze documents
- solve math and code
- make decisions
- conduct research
- build presentations and reports
The bar for “AI-powered work” has officially been raised.
