AI War: OpenAI Launches GPT-5.2 After ‘Code Red’ to Catch Gemini 3
San Francisco – The gloves are off. OpenAI officially launched its newest models, GPT-5.2 Pro and GPT-5.2 Thinking, just weeks after Google’s Gemini 3 Pro started making serious gains, prompting an internal panic known as “code red” at OpenAI.OpenAI code red, Sam Altman, Gemini 3 Pro, GPT-5.2 Thinking, AI benchmark, professional knowledge work
This is the ultimate tech showdown: the pioneer versus the juggernaut.
The Great AI Race Flip
The Challenger’s Rise: Google’s Gemini 3 Pro was beating the previous ChatGPT models on multimodal tasks, reasoning, and, critically, avoiding the “hallucination” issues that had plagued the earlier iteration of ChatGPT.
The Code Red: OpenAI CEO Sam Altman reportedly issued a “code red” to his teams, urging them to halt non-essential projects and accelerate development to keep pace with Google’s relentless innovation. OpenAI Chief of Applications Fidji Simo confirmed the “red alert” about Google sprinting ahead.
GPT-5.2’s New Weapon: Pure Reasoning
OpenAI has positioned GPT-5.2 not as a chat upgrade, but as a serious tool for “professional knowledge work,” prioritizing logic and accuracy over flashy features. The two new variants target specific needs:
GPT-5.2 Pro: The top-tier model for overall quality and accuracy, showing improvements in complex coding and long-context performance. On the SWE-bench Verified code test, GPT-5.2 reportedly scored 80%, slightly ahead of Gemini 3 Pro’s 76.2%.
GPT-5.2 Thinking: Designed specifically for deep work, math, and science. OpenAI stated, “Strong mathematical reasoning is a foundation for reliability in scientific and technical work.” It reportedly achieved a perfect 100% on its internal AIME 2025 math benchmark (without tools), compared to Gemini 3’s 95%.
The Benchmark Battle is Mixed
Early independent user tests and company-reported benchmarks show a mixed bag, indicating a truly narrow divide:
| Benchmark | GPT-5.2 Lead | Gemini 3 Lead |
| Math/Code Accuracy | GPT-5.2 (SWE-bench, AIME) | – |
| Science/Reasoning | GPT-5.2 (GPQA Diamond: 92.4% to 91.9%) | – |
| Multimodality | – | Gemini 3 (MMMLU: 91.8% to 89.6%) |
| Broad Reasoning | – | Gemini 3 (Humanity’s Last Exam) |
| Web Development | GPT-5.2 High (2nd on LMArena) | – |
For now, the overall picture is unclear whether OpenAI can fully reclaim the lead in the near term. The race continues, and the user benefits from this high-stakes, ultra-expensive competition.
