AI Weekly News Briefing: Nvidia’s Surge, Model ML’s $75M & AI Growth Zones in the UK

This week we’re looking at AI moving from hype to hands-on. We start with OpenAI and DoorDash running “AI Jam” workshops for over 1,000 small businesses across US cities – helping restaurant owners, accountants and retailers build AI tools they can actually use the next day. Meanwhile, the tech giants are doing the opposite of slowing down: nearly $90 billion raised in fresh bonds to fuel data centres, GPUs and cloud infrastructure. Nvidia smashed expectations again (with numbers even stronger than headlines suggest), Model ML just banked $75m to automate investment banking grunt work, and a mid-tier London accounting firm cut a two-week task down to two hours using Gemini 2.5. At the same time, Amazon is telling engineers to ditch third-party coding assistants for its in-house AI tool “Kiro”, and the UK government wants regional AI Growth Zones to make AI adoption easier for business – though the details are fuzzier than the headline. We pull it all together through one lens: AI is embedding fast at both ends of the market – from small cafés drafting menus in a workshop, to hyperscalers dropping billions to keep the GPU taps flowing. If you're building or scaling with AI, this episode gives you a heads-up on what’s coming next.
