Mistral raises €3B to make sovereign, open-weight AI the technology frontier
Mistral AI has released the open-weight model 'Mistral Large 4' on Hugging Face after a three-week preview. This flagship multimodal model, trained on 3,800 Nvidia accelerators, features 1 trillion parameters, making it too large for consumer hardware. Early access partners included ASML, Cisco, CrowdStrike, Microsoft, and the European Space Agency. According to Mistral, it outperforms Chinese rivals like GLM-5.3 and Kimi K3 on the CyberGym-E2E cybersecurity benchmark and matches GLM-5.3 on Terminal Bench 4.0, an agentic coding benchmark, though independent evaluations are pending. Preview pricing was $1.4 per million input tokens and $4.2 per million output tokens, cheaper than Kimi K3.1 Pro. Smaller quantized versions are planned. The company recently raised €3 billion in a Series D round at a post-money valuation of over €21 billion to fund development and compute expansion.
