Thursday, May 21Thursday, May 21OpenAI has achieved a significant breakthrough in AI reasoning by solving the 80-year-old *planar unit distance problem*, originally posed by mathematician Paul Erdős in 1946. This advancement demonstrates progress in AI’s ability to tackle complex mathematical challenges, reinforcing its potential for high-level problem-solving .
The AI inference boom is driving demand for innovative energy solutions and infrastructure. European AI infrastructure upstart Nebius has partnered with Bloom Energy in a $2.6 billion deal to deploy fuel-cell technology at its data centers, enabling faster and more efficient electricity generation to support AI workloads . Meanwhile, Antimatter, a French startup founded by tech entrepreneur David Gurlé, is addressing the inference boom with mini data centers housed in containers, offering cost-effective and scalable energy solutions for AI execution . Additionally, the world’s largest vanadium flow battery project has selected UK startup Invinity Energy Systems to meet the surging energy demands of AI-driven data centers .
European AI startups continue to attract substantial investment, with over €5.3 billion raised in 2025. Leading the funding surge are companies like Mistral AI, Helsing, Black Forest Labs, Synthesia, ElevenLabs, and n8n, reflecting strong investor confidence in the continent’s AI ecosystem . In the UK, Imperagen has secured £5 million in seed funding to advance AI-driven enzyme engineering, further highlighting the intersection of AI and biotech innovation .
