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.
The switch by a major European search engine to Chinese AI models underscores the challenges for European AI sovereignty and highlights the competitive gap of European AI models. It impacts the AI ecosystem and tech choices in Europe.

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.
Mistral opens infrastructure to rival AI models
French AI startup Mistral has begun hosting third-party models on its infrastructure, notably making GLM-5.2 (an open-weights model from Chinese lab Z.ai) available, and has signalled a closer partnership with Microsoft announced in July. The move suggests Mistral is softening a frontier-model strategy focused solely on its own weights after large funding rounds and EU state support. The article frames this as both an admission that Mistral’s models alone may not win the generalist LLM race and an opportunity to focus on niche industrial use cases and specialised models (e.g., OCR).
Mistral launches Large 4, rivals top open models
French AI lab Mistral AI has launched Mistral Large 4 (ML4, 'Le Chonk'), a 1-trillion-parameter multimodal model with 49 billion active parameters, positioned as a 'third way' between closed and open-weight models. It excels in coding, cybersecurity, visual grounding, and enterprise tasks. Independent benchmarks rank it among the world's top five open-weight models, with an Intelligence Index score of 38.4, on par with GPT-6 Luna and DeepSeek V4.1 Flash, but behind closed models like Claude Opus 5.5. Trained on ~3,800-4,000 Nvidia Grace Blackwell GPUs in European data centers, it is available as an API preview via Mistral Studio, with weights due after safety testing by October 27, 2026. Pricing is $1.36 per million input tokens and $4.18 per million output tokens (approximately $1.13 per task). The model supports 160 languages, including all official EU languages. Mistral raised €3 billion in September 2026 at a €21 billion valuation to support Neocloud infrastructure, marking the largest equity financing for a European tech company.
