Open AI

OpenAI released GPT-5.2 on December 11, 2025. This model focuses on professional work and advanced reasoning. It comes one week after Google showed dominance with Gemini 3. OpenAI has reclaimed the top spot on several industry leaderboards.

Benchmark Success

GPT-5.2 shows high performance in many areas. It achieved a 55.6 percent success rate in software engineering tasks. It scored 92.4 percent on high level science questions. This score beats both Gemini 3 Pro and Claude Opus 4.5. Hallucinations have also dropped by up to 40 percent compared to older versions.

Breaking Reasoning Records

The model reached a 90.5 percent score on the ARC-AGI leaderboard. This test checks if a model can solve new problems. It does not rely on memorization. OpenAI also improved efficiency by 390 times in just one year. This makes the model much cheaper to use than previous versions.

New Partnerships and Marketing Lessons

OpenAI signed a one billion dollar deal with Disney. Users can now create content with characters from Marvel, Pixar, and Star Wars. This includes famous figures like Mickey Mouse and Darth Vader. However, AI marketing still faces challenges. McDonald's recently pulled an AI commercial because the public found it scary. Creative work still requires a human touch.

Trading Controversies

Prediction markets accurately guessed the launch of GPT-5.2. Some experts worry about insider trading. They suggest employees might be betting on release dates and scores they already know. This has sparked a debate about ethics in the AI industry.

The Future of Reasoning

GPT-5.2 proves that AI scaling laws are still working. The jump in reasoning is clear. Developers now have a more reliable tool for coding and research. Whether this is true AGI remains a topic for debate.
