Google Gemini 2.5 Pro surpassed OpenAI o3 and leads on LMArena
Google updated Gemini 2.5 Pro with strong benchmark gains. Now the model surpasses the current o3 version from OpenAI. Like 2.5 Flash, this is a hybrid model that allows setting budget for thinking processes or completely turning them off. The model is already available and according to first impressions works better than early versions. It even listens when you ask it not to spam code with comments.
On LMArena arena, the new version rose by 24 Elo points compared to the previous one and now leads in all categories, surpassing o3 and Claude Opus 4. On benchmarks, the model noticeably improved and became more efficient in code, logic and exact sciences tasks.
The results are impressive. 82.2% on programming tasks, 86.4% on natural sciences questions and 21.6% on Humanity’s Last Exam test, which checks thinking and knowledge.
Developers also took into account feedback about the previous version and improved style and structure. Now the model can be more creative. They also added budgets for thinking processes for greater cost control. Unfortunately, image generation for Gemini Pro was still not added.
