French AI lab Mistral has released Mistral Large 4, its new flagship model:
- Scale & openness: 1 trillion parameters, open weights, available on Hugging Face for anyone to download, run, and modify.
- Positioning: Mistral calls it the best open model built in the West, claiming 'frontier' performance among open models for agentic coding and cyber defense.
- Context: Open-weight leadership has traditionally come from Chinese companies; Mistral frames this release as catching up with its Chinese rivals. Fortune's report includes the caveats behind the marketing claims.
