Google Launches Gemini 3 Pro with 'Generational Leap' in Vision AI, Surpassing 650M Monthly Users

Google announced Gemini 3 Pro on December 5, 2025, describing the release as a "generational leap from simple recognition to true visual and spatial reasoning." The new model represents Google's most capable multimodal AI system to date, delivering state-of-the-art performance across document understanding, spatial reasoning, screen interaction, and video analysis. Gemini 3 Pro sets new benchmarks on leading vision AI tests, including MMMU Pro and Video MMMU. The model can reason across text, images, audio, and video simultaneously—a capability that Google says enables more natural and powerful AI interactions than previous generations. The launch comes as Google reports explosive growth in its AI products. The Gemini app has surpassed 650 million users per month, while AI Overviews in Google Search now reaches 2 billion users monthly. These figures underscore the rapid mainstream adoption of generative AI tools just three years after ChatGPT's debut. Google is rolling out Gemini 3 Pro immediately to all users of the Gemini app. The company says the model brings "state-of-the-art reasoning" and represents their "best vibe coding model yet," suggesting improvements in both analytical capabilities and user experience. Additionally, Google AI Ultra subscribers now have access to Gemini 3 Deep Think, the company's most advanced reasoning mode. Deep Think uses iterative rounds of reasoning to explore multiple hypotheses simultaneously, making it particularly effective for complex tasks in mathematics, science, and logic. The competitive impact of Gemini 3 has been immediate. OpenAI CEO Sam Altman reportedly declared a "Code Red" in an internal memo following Google's release, marshaling resources to improve ChatGPT in response to the competitive threat. Salesforce CEO Marc Benioff praised Gemini 3 on social media, calling the improvements in "reasoning, speed, images, video" insane. Google's aggressive deployment strategy—what the company called its "fastest-ever" rollout into Google Search—demonstrates the tech giant's determination to reclaim leadership in the AI race after initially ceding ground to OpenAI's ChatGPT.
