Mistral AI joins plan for Europe's largest AI data center near Paris
At the Choose France summit held on May 19 in Versailles, France announced a joint venture to develop what is planned to be the largest AI campus in Europe, located in the Île-de-France region. The project targets 1.4 gigawatts of computing capacity, equivalent to roughly 560,000 next-generation Nvidia GB200 chips, which would make it larger than xAI's Colossus cluster. The joint venture partners include French public investment bank Bpifrance, UAE-based AI-focused fund MGX, French AI unicorn Mistral AI, and chip leader Nvidia. The initiative follows UAE-France AI cooperation agreements from February 2025. The summit generated a record €37 billion in investment announcements, including nearly €9 billion for data centers from Prologis and Digital Realty and €10 billion from Brookfield, reinforcing France's status as Europe's top destination for foreign direct investment.
Major AI infrastructure investment in Europe involving a key LLM player (Mistral AI) and Nvidia; relevant to the tech infrastructure underpinning AI-driven advertising and martech.

Ecosia Drops Mistral for Chinese Open-Source AI
European search engine Ecosia has switched its AI supplier from French startup Mistral to open models, including Chinese ones like Alibaba's Qwen, Z.ai's GLM, and Moonshot AI's Kimi. CEO Christian Kroll cited disappointment with Mistral's model quality, which he says lags about a year behind competitors, and frequent server overloads. Ecosia now uses models via German platform Melious, which runs open AI models on EU servers, halving AI service costs while improving performance. The switch comes as Mistral released Large 4, its most powerful model yet, trained in Europe with open weights due in October. Despite scoring 38.4 on the Intelligence Index, it ranks eighth among open models, behind seven Chinese models. The case highlights the European AI sovereignty dilemma: top-tier open models are predominantly Chinese, even when run on European servers. Mistral itself hosts Chinese models like GLM on its neocloud platform, while its CEO Arthur Mensch defends Large 4's capabilities in areas like cyber defense.
Ecosia Switches from Mistral to Chinese AI Models
Berlin-based search engine Ecosia has dropped French AI provider Mistral and switched to open-weight models, including Chinese ones like Qwen (Alibaba), GLM (Z.ai), and Kimi (Moonshot AI), as reported by Politico. Ecosia CEO Christian Kroll was reportedly disappointed with Mistral's model quality, saying they lag behind competitors by about a year, and also questioned Mistral's sovereignty due to its reliance on international investors. Ecosia now sources models via Melious, a German platform running open AI models on European servers, cutting AI costs by half while improving performance. Mistral, meanwhile, released Large 4, a trillion-parameter model trained in European data centers, which ranks eighth among open models, with all top seven being Chinese. This highlights Europe's AI sovereignty dilemma: top open models are mostly Chinese, even as Mistral itself now hosts Chinese models like GLM on its neocloud.
OpenAI Publishes 722 AI Math Papers
OpenAI released 722 mathematical manuscripts on GitHub, organized into 372 result families, addressing problems in number theory, algebraic geometry, and theoretical computer science, including a quasi-Riemann hypothesis. The proofs, generated by an unreleased language model, each took about three hours of compute, compared to months or years for humans. They are formalized in Lean for verifiability, though only 42% are formalized and only 10 of 719 include chain-of-thought releases. An advisory group (AGMAI) criticized OpenAI for not meeting guidelines on human understanding and for lacking machine-readable metadata correlating natural language and formal artifacts. A paper by Cambridge and King's College London highlighted discrepancies between natural language proofs and Lean code in a Navier-Stokes solution. Additionally, researchers accuse OpenAI and Anthropic of using private interactions to replicate unpublished work, but both companies deny this. Experts like Terence Tao stress the need for human engagement, and ethical debates over credit and originality persist.
