In a competitive landscape of artificial intelligence, recent benchmarks have shown that OpenAI’s ChatGPT-5.2 outperforms Google’s Gemini 3 Pro in several critical areas. The evaluation focused on three significant metrics: reasoning, problem-solving, and abstract thinking. This analysis highlights the strengths of each system and provides insight into the evolving capabilities of AI technologies.
Benchmark Comparisons Highlight ChatGPT’s Strengths
Comparing AI systems is challenging, especially as advancements occur rapidly. For instance, in December 2025, OpenAI released ChatGPT-5.2, which reignited discussions about its performance relative to competitors. In this context, benchmarks serve as a valuable tool to assess capabilities.
The first major benchmark examined was the GPQA Diamond test, designed to evaluate advanced reasoning in fields like physics, chemistry, and biology. This test features complex questions that require comprehensive reasoning rather than simple recall of facts. ChatGPT-5.2 achieved a score of 92.4%, slightly ahead of Gemini 3 Pro, which scored 91.9%. Notably, a typical PhD graduate is expected to score around 65%, while non-expert participants average 34%.
The second benchmark, SWE-Bench Pro (Private Dataset), assesses AI’s ability to solve real-world software engineering tasks sourced from GitHub. This benchmark is particularly tough due to its use of non-public data, making it a more rigorous test of AI capabilities. Results indicated that ChatGPT-5.2 was able to resolve 24% of the issues presented, compared to Gemini’s 18%. While these percentages may seem modest, they reflect the complexity of the tasks, where human engineers achieve close to 100% success.
Lastly, the ARC-AGI-2 benchmark, launched in March 2025, assesses abstract reasoning capabilities. It challenges AI to recognize patterns and apply them to new scenarios. In this test, ChatGPT-5.2 scored 54.2%, while Gemini 3 Pro fell significantly behind at 31.1%. This benchmark highlights an area where AI still struggles compared to human intelligence, yet ChatGPT demonstrates a lead over Gemini’s various models.
Acknowledging Limitations and Future Developments
Despite these results favoring ChatGPT, it is essential to recognize the rapid evolution of AI technologies. Each new release from either OpenAI or Google can significantly alter performance metrics and rankings. For instance, while ChatGPT-5.2 outperformed Gemini 3 Pro in the selected benchmarks, there are many areas where Gemini excels, such as the SWE-Bench Bash Only and Humanity’s Last Exam benchmarks.
The selection of benchmarks for this analysis aimed to provide a balanced view of AI capabilities across different domains. While other benchmarks exist, such as GDPval-AA and FrontierMath, the focus here was on those that clearly illustrated ChatGPT’s advantages in specific areas.
As AI continues to advance, ongoing evaluations will be crucial for understanding each system’s strengths and weaknesses. The methodologies used in these benchmarks provide a more reliable assessment than subjective comparisons based solely on user preferences. Nonetheless, platforms like LLMArena indicate that user preferences currently favor Gemini, demonstrating the importance of considering various evaluation methods.
In summary, the current benchmarks reveal that ChatGPT-5.2 holds a competitive edge over Gemini 3 Pro in critical areas such as reasoning, problem-solving, and abstract thinking. As developments unfold, the landscape of AI will continue to shift, making it imperative for users and developers alike to stay informed about the latest capabilities and performance metrics.
