Mistral launches open‑weight 'frontier AI family' to challenge DeepSeek and US rivals

French startup Mistral released a four‑model "frontier AI family," including a 675‑billion‑parameter sparse Mixture‑of‑Experts model dubbed Mistral Large 3, all under the permissive Apache 2.0 open‑weight license. The models, trained on thousands of Nvidia H200 GPUs, are pitched as state‑of‑the‑art multimodal and multilingual systems that enterprises can run and fine‑tune locally, giving privacy‑sensitive European customers an alternative to Chinese lab DeepSeek and US closed‑weight offerings from OpenAI and Google.
