Yesterday’s Most Impactful AI News
Weekly Edition (September 7 – 13, 2025)
This week in AI was dominated by billion-dollar bets, global competition, and scientific breakthroughs with real-world impact. From Nvidia and OpenAI’s massive UK investment to MIT’s flu vaccine tool, the stakes have never been higher.
Here are the five stories you need to know.
TL;DR – This Week’s Top 5 AI Stories
Nvidia and OpenAI drive a multi-billion UK AI infrastructure deal
AI startups raise a record $2.8B in one week
Microsoft ramps up infrastructure to go independent from OpenAI
MIT’s VaxSeer tool could transform flu vaccine effectiveness
China claims “brain-like” AI with 100x faster performance
1. Nvidia and OpenAI Bet Big on UK AI Infrastructure
In collaboration with Nscale, Nvidia and OpenAI are about to invest billions in UK data centers. This move positions the UK as a key AI hub. It reflects the growing “sovereign AI” trend, where countries aim to control their own computing resources instead of depending on foreign providers.
2. Record $2.8B AI Funding Week
This week shattered records as investors poured more than $2.8 billion into AI companies:
Databricks raised $1B at a $100B valuation
PsiQuantum secured $1B for quantum computing
Cognition pulled in $400M at $10.2B valuation
Perplexity closed $200M, hitting $20B valuation
The funding frenzy highlights where the market perceives AI’s greatest potential: platforms, quantum, and developer tools.
3. Microsoft Expands AI Infrastructure
Microsoft is increasing its focus on developing in-house models and expanding server capacity to decrease reliance on OpenAI. The company’s MAI-1 preview was just the start. This move indicates a new phase in big tech competition, with infrastructure control becoming the main battleground.
4. MIT’s VaxSeer Improves Flu Vaccine Selection
MIT researchers introduced VaxSeer, an AI tool that forecasts virus evolution to assist in flu vaccine strain selection. By enhancing accuracy, VaxSeer could make yearly vaccines much more effective — a breakthrough with direct benefits for global public health.
5. China’s “Brain-Like” AI Claims 100x Speed
Chinese researchers announced a new model they claim mimics brain architecture and operates 100 times faster than conventional AI. Although still unverified, the claim underscores escalating international competition. If proven, it could represent a significant leap in AI efficiency and performance.
