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.
