Gemini 3.1 Pro: Advanced reasoning for complex tasks
Google has rolled out Gemini 3.1 Pro, the latest in its Gemini AI family, designed to handle tasks where simple answers aren’t enough. Google claims 3.1 Pro delivers roughly double the reasoning performance of the November 2025–released Gemini 3 Pro, unlocking capabilities for complex data synthesis, visual explanations, and creative visuals in UX design and marketing workflows. The update follows Gemini 3 Deep Think, further emphasizing agentic workflows. Rollout is in Preview via the Gemini App for AI Ultra and Pro subscribers, with NotebookLM support, and API access through AI Studio, Antigravity, Vertex AI, Gemini Enterprise, Gemini CLI, and Android Studio. It’s also available in other environments such as the Perplexity AI Answering Machine. The article highlights use cases like generating data tables, creating animations, and even analyzing literary topics (e.g., Wuthering Heights) to inform websites or portfolios, illustrating Google’s push toward more capable, reasoning-focused AI tools.
Google Gemini 3 Elevates Search and App AI
Google announces Gemini 3, its latest AI model, integrated directly into the Google Gemini App and activated in Search via AI Mode. The model promises multimodal understanding, nuanced responses, and generative layouts, with agentic capabilities that support multi-step tasks and coding. Gemini 3 is supported by a new Antigravity platform for Vibe Coding, enabling autonomous agent actions and app-level workflows; developers can access Gemini 3 through Google AI Studio, Vertex AI, Gemini CLI, and the new Agentric-Building platform Antigravity. The rollout emphasizes deep integration across Google services (Maps, Canvas, Chrome) and introduces enhanced AI capabilities for developers and end users. Google notes Gemini 3's broad reach (650 million monthly active users; 13 million developers) and cites performance benchmarks from internal assessments. Availability begins in the US for Pro/Ultra users, with broader deployment including Germany planned later. The company positions Gemini 3 as a major step in its AI strategy against competitors like OpenAI, Meta, and Anthropic.
Gemini 3 Flash Becomes Default AI Mode Model
Google announces Gemini 3 Flash as the default model for its Gemini App, AI Mode in Google Search, and related AI workflows, emphasizing speed and efficiency. The model introduces features such as Agent CC for Gmail and a Disco Browser, and is positioned as faster and more token-efficient than Gemini 2.5. In benchmarks, Gemini 3 Flash reportedly outs as fast or faster than competing models, with a 33.7% score on Humanity’s Last Exam and improved output latency. The system is described as using about 30% fewer tokens on average than Gemini 2.5 and being three times faster, with costs cited at roughly $0.50 per million input tokens and $3 per million output tokens. Access for enterprises is via Vertex AI and Gemini Enterprise, while developers can use the Gemini API in Google AI Studio, Gemini CLI, and the new Google Antigravity platform. The rollout is described as global, establishing Gemini 3 Flash as a foundational AI capability for search and apps.
