Gemini 3 vs Gemini 2.5 Pro vs GPT 5.1

Google has officially announced Gemini 3.0, the newest flagship model in its generative AI lineup, focusing heavily on scientific reasoning, mathematics, multimodal understanding and long-horizon agentic tasks. Early benchmark data shows that Gemini 3.0 improves significantly over Gemini 2.5 Pro and posts competitive, often superior, performance against GPT-5.1 across several categories.

Gemini 3.0’s strongest gains are visible in tasks involving scientific knowledge (GPQA Diamond), math competitions, agentic tool use, coding benchmarks, and long-horizon decision-making. The model also delivers major improvements in multimodal reasoning benchmarks such as MMMU-Pro and ScreenSpot-Pro, marking a step-change for interactive and real-time use cases.
