UK Gets £24B AI Investment: Gemini 3 Launches, Copilot for SMBs (17-24 Nov 2025)

This week marks a turning point for UK businesses watching AI developments. The Government's largest-ever AI investment coincides with major product launches that directly affect small and medium-sized businesses. Understanding these changes helps business owners make informed technology decisions.

What Does the UK's £24 Billion AI Investment Mean for Small Businesses?

The UK Government's £24 billion AI investment package, announced 20 November 2025, includes £5 million per AI Growth Zone specifically for local business adoption and skills development. Microsoft and Vantage Data Centers are investing £10 billion in South Wales alone, creating 5,000 jobs across the M4 corridor.

The investment positions Britain as a global AI leader. South Wales receives a new AI Growth Zone at the former Ford Bridgend Engine Plant. This creates employment opportunities for businesses in manufacturing, technology, and support services throughout the region.

The AI for Science Strategy launched on the same day allocates £137 million for research applications. This funding develops autonomous laboratory platforms, AI-ready datasets, and trains over 1,000 doctoral researchers in AI disciplines. The first mission targets drug development within 100 days by 2030.

Which AI Companies Are Opening UK Offices?

Several major AI companies announced UK expansion plans during November 2025. These investments bring high-value jobs and position London as a European AI hub alongside established tech centres.

• Perplexity AI: £80 million investment in London offices, creating 100 jobs
• Cursor AI: Opening London as European headquarters—the company's first international expansion
• Graphcore & SoftBank: New AI development lab in Bristol, doubling headcount to 750 jobs
• Cerebras: Expanding partnerships with EPCC at University of Edinburgh

What Is Google Gemini 3 and Why Does It Matter?

Google launched Gemini 3 on 18 November 2025, immediately deploying it to 2 billion users via AI Overviews in Search and 650 million Gemini app users. The model achieved a record 1501 Elo score on LMArena, surpassing the previous Gemini 2.5 Pro score of 1451. This affects how AI answers user queries.

Gemini 3 introduces Generative UI, which creates interactive web applications, calculators, and simulations directly from text prompts. Users asking complex questions receive functional tools rather than static text answers. This changes how businesses present information for AI citation.

Google also launched Antigravity IDE alongside Gemini 3. This agentic development platform features a multi-pane interface where AI agents autonomously plan and execute software tasks. The platform runs on Mac, Windows, and Linux, available to developers immediately.

Gemini 3 Benchmark Performance

Benchmark	Gemini 3 Score
Humanity's Last Exam	37.5% (without tools)
GPQA Diamond	91.9%
MathArena Apex	23.4% (new state-of-the-art)
LMArena Elo Score	1501 (record)

What New Features Does OpenAI's GPT-5.1 Offer?

OpenAI released GPT-5.1 on 12-13 November 2025 in two variants: Instant and Thinking. GPT-5.1 Instant offers a warmer conversational tone with 8 personality presets. GPT-5.1 Thinking provides adaptive reasoning that allocates more processing time to complex tasks. Developers receive 24-hour prompt caching.

The personality presets in GPT-5.1 Instant include Default, Professional, Friendly, Candid, Quirky, Efficient, Nerdy, and Cynical. Businesses using ChatGPT for customer service can select tones matching their brand voice. This customisation previously required complex prompt engineering.

GPT-5.1-Codex-Max launched the same week, designed for long-running software engineering tasks. The model maintains coherence across hundreds of thousands of lines of code using a dynamic memory compression mechanism. This supports 24-hour internal tasks like multi-step code refactoring.

Why Did Cursor AI Reach a £29.3 Billion Valuation?

Cursor completed Series D funding in November 2025 at a £29.3 billion valuation with £1 billion in annualised revenue. University of Chicago research found companies merge 39% more pull requests after Cursor's agent became the default coding tool. New multi-agent features run up to 8 AI agents in parallel from a single prompt.

Cursor 2.0 introduces the Composer Model, the company's first proprietary coding model. This model runs 4 times faster than comparably intelligent alternatives. Cloud Agents provide 99.9% reliability with instant startup times. Semantic Search improves coding agent accuracy by 12.5%.

Investors in the Series D round include Accel, Thrive, a16z, Coatue, NVIDIA, and Google. The company's choice of London for European headquarters signals confidence in UK tech talent. Development teams considering AI coding tools should evaluate Cursor alongside GitHub Copilot.

How Do These AI Developments Affect Search Visibility?

Gemini 3's deployment to 2 billion Google Search users directly impacts how businesses appear in AI-generated answers. Content structured for AI extraction receives more citations. Pages with FAQ format get cited 89% more often than unstructured alternatives. Businesses must optimise for both traditional search and AI citation.

Google AI Overviews now use Gemini 3's improved reasoning capabilities. The Generative UI feature means users receive interactive tools instead of simple text answers. Businesses providing calculators, comparison tools, or interactive content may see increased visibility in AI responses.

Perplexity's Comet Browser for Android launched in November 2025 with built-in AI search capabilities. The browser includes voice mode and tab summarisation. As AI-native browsers gain users, content optimised for AI citation becomes essential for maintaining search visibility.
