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 has released a dataset of 722 mathematical manuscripts on GitHub, organized into 372 result families spanning number theory, algebraic geometry, and theoretical computer science. The proofs, generated by an unreleased language model, each required roughly three hours of compute, compared to months or years of human effort. They address many top open problems, including a quasi-Riemann hypothesis, and are formalized in the Lean proof assistant for verifiability. OpenAI consulted an advisory group against using results for marketing and plans to fund conferences for academic evaluation. However, the release has sparked ethical debates over credit and originality, especially as researchers accuse OpenAI and Anthropic of using private interactions to replicate unpublished work. Mathematicians Tristan Buckmaster, Andreas Thom, and biologist Mario Rodríguez Mestre allege their unpublished research was used by these AI models. Both companies deny the accusations, citing policies against training on user conversations, but experts note the difficulty of proving such claims, raising concerns about a chilling effect on open scientific collaboration.
