ChatGPT-5.2. Is OpenAI Catching Up With Google’s AI Models? – AI News – #3 December 2025

The arms race in the world of artificial intelligence has just picked up the pace. OpenAI has officially launched GPT-5.2, describing it as their most advanced “pioneer model” for professional applications. This premiere is a direct response to the rising dominance of Google’s Gemini 3, which has reigned supreme in LMArena rankings in recent weeks.

Is GPT-5.2 enough for OpenAI to reclaim the yellow jersey? Let’s look at the details, benchmarks, and what this shift means for the SEO and marketing industry.

OpenAI’s main goal in designing the 5.2 series was to maximize efficiency in the workplace. According to company data, ChatGPT Enterprise users already save an average of 40–60 minutes per day, with “power users” saving up to 10 hours a week. GPT-5.2 is designed to push these numbers even higher.

The model has been released in three variants to better suit specific tasks:

OpenAI boasts impressive results in new benchmarks. In the GDPval test, which measures performance across 44 knowledge-based professions, GPT-5.2 Thinking outperforms industry specialists in 70.9% of tasks (for comparison, GPT-5 achieved a score of 38.8%).

Interestingly, the model performs these tasks 11 times faster than a human, at a fraction of an expert’s cost.

For developers and technical SEO specialists, GPT-5.2 brings revolutionary changes. In the SWE-Bench Pro test, which simulates real software engineering work (multi-file projects, debugging, refactoring), the model achieved a score of 55.6%.

Key improvements include:

This is the most important question the industry is asking. The debut of GPT-5.2 comes at a time when Gemini 3 from Google dominates the rankings, especially in terms of multimodality (working with image, video, and text simultaneously).

The market situation is currently very dynamic:

Aidan Clark from OpenAI emphasizes that the improvement in results is not just “better counting,” but the ability to maintain a logical train of thought in multi-step projects—which has been the Achilles’ heel of many previous models.

For the SEO industry, where information precision is key (especially in the era of E-E-A-T), the reduction in hallucinations is good news. In “Thinking” mode, the model commits 38% fewer errors than its predecessor. This means safer use of AI for research, content creation, or market data analysis.

The models are being rolled out gradually for users on paid plans (Plus, Team, Enterprise). It is worth noting the changes in the API:

The biggest absentee of the premiere is a new image generator. While Google celebrates triumphs with the Gemini 2.5 Flash Image model (“Nano Banana”), OpenAI still keeps us waiting for the successor to DALL-E 3. Rumors suggest a launch in January, which is expected to bring not only better quality but also a stronger “personality” to the visual model.

The world of AI changes from week to week, and the rivalry between Google and OpenAI directly impacts SEO and marketing strategies. Don’t let these changes catch you off guard.
