• Mistral AI open-sources trillion-parameter Mistral Large 4
  Mistral AI released the open weights of Mistral Large 4 ("Le Chonk"), its 1-trillion-parameter natively multimodal flagship that now leads open-weight benchmarks in agentic coding and defensive cybersecurity while using 47% fewer tokens per task than GLM-5.3, positioning it as a foundation for European sovereign AI; TechCrunch reported that the release lets businesses and governments download and self-deploy frontier AI for cyber defense. Ecosystem support arrived day-0, with Unsloth's 1-bit GGUF quantization enabling the 1T model to run locally on a Mac Studio, vLLM shipping serving optimizations with up to 2.23x output throughput, TRL adding single-node post-training support for LoRA SFT on the model, and llama.cpp merging support for the architecture.

• Arthur Mensch urges Europe to build frontier AI
  Mistral AI co-founder and CEO Arthur Mensch publicly argued that Europe conceding frontier AI development to the US and China would be "a fundamental mistake," framing the decision as "build or surrender" and insisting the choice remains Europe's to make. The statement pushes back against a growing view in Europe that it cannot compete at the frontier, coming from the CEO of Europe's most prominent frontier AI lab. (x.com)
