The Dawn of a New AI Era

On November 18, 2025, Google unveiled Gemini 3, what the company describes as the beginning of "a new era of AI intelligence." This isn't just an incremental update-it represents a fundamental leap forward in artificial intelligence capabilities, bringing together breakthrough features that redefine what's possible with AI.

Record-Breaking Performance

Gemini 3 Pro has achieved an unprecedented score of 1501 on the LMArena leaderboard, surpassing its predecessor Gemini 2.5 Pro's score of 1451. The model demonstrates exceptional performance across virtually all major benchmarks, including:

Reasoning Excellence: 91.9% on GPQA Diamond (PhD-level science questions) and 37.5% on Humanity's Last Exam-surpassing even xAI's recent Grok 4.1 release.

Mathematical Mastery: A new state-of-the-art score of 23.4% on MathArena Apex, demonstrating deep mathematical reasoning beyond mere calculation.

Multimodal Understanding: 81% on MMMU-Pro and an impressive 87.6% on Video-MMMU, showcasing exceptional ability to reason across text, images, and video.

Deep Think: Enhanced Reasoning Mode

Alongside Gemini 3 Pro, Google introduced Deep Think-an enhanced reasoning mode that allocates additional computational resources for the most challenging problems. On ARC-AGI-2, a benchmark designed to test genuine reasoning ability rather than pattern matching, Deep Think achieves an unprecedented 45.1% accuracy, demonstrating a significant leap in AI reasoning capabilities.

Revolutionary Generative UI

Perhaps the most innovative feature is generative UI-where Gemini 3 doesn't just generate content but creates entire custom user interfaces on the fly. Need a mortgage calculator? A physics simulation? A personalised learning experience? Gemini 3 can generate bespoke interfaces tailored to your specific needs, eliminating the need to search for pre-existing tools.

Google Antigravity: The Future of Development

Complementing Gemini 3 is Google Antigravity, a revolutionary agentic development platform that transforms the traditional IDE experience. Powered by Gemini 3 combined with computer use capabilities, Antigravity enables AI agents to work autonomously across your editor, terminal, and browser-planning and executing complex development tasks with minimal human intervention.

Availability and Pricing

Gemini 3 Pro is available immediately across the Gemini app, Google Search AI Mode, Google AI Studio, and Vertex AI for enterprises. API pricing starts at $2 per million input tokens and $12 per million output tokens for prompts under 200,000 tokens.

What This Means for the Future

Gemini 3 represents more than just improved benchmarks-it signals a shift in how we interact with AI systems. The combination of superior reasoning, native multimodality, generative UI, and agentic autonomy creates possibilities that were previously impractical. As Google describes it, this is truly "a new era of intelligence."

Frequently Asked Questions

How does Google Gemini 3 compare to ChatGPT and Claude?

Gemini 3 Pro achieved a score of 1501 on the LMArena leaderboard, surpassing all competitors at launch. It scores 91.9% on PhD-level science questions and 37.5% on Humanity's Last Exam. Its unique features like generative UI and the Deep Think reasoning mode set it apart from both OpenAI's GPT series and Anthropic's Claude models.

What is generative UI and how can businesses use it?

Generative UI allows Gemini 3 to create custom interactive interfaces on the fly based on your request. Instead of searching for a mortgage calculator or data visualisation tool, you simply describe what you need and Gemini builds it instantly. Businesses can use this for custom dashboards, calculators, interactive presentations, and client-facing tools without any development time.

How much does Gemini 3 cost to use?

Gemini 3 Pro is free to use through the Gemini app and Google Search AI Mode. For developers and enterprises, API pricing starts at $2 per million input tokens and $12 per million output tokens for prompts under 200,000 tokens. Enterprise access is available through Google AI Studio and Vertex AI.

What is Google Antigravity and how does it work?

Google Antigravity is an agentic development platform powered by Gemini 3. It enables AI agents to work autonomously across your code editor, terminal, and browser, planning and executing complex development tasks with minimal human intervention. It transforms the traditional IDE experience by combining AI reasoning with computer use capabilities.

What does Gemini 3 mean for UK businesses adopting AI?

Gemini 3 makes advanced AI more accessible and affordable for UK businesses. The free tier through the Gemini app lets small businesses experiment without cost. The generative UI feature removes the need for custom tool development. For businesses already using Google Workspace, Gemini 3 integration means AI capabilities are embedded directly into existing workflows.
