European Lab Builds 1‑Trillion Open Model

Mistral announced Mistral Large 4 ('le Chonk'), a 1‑trillion‑parameter open‑weight model entering developer preview and claimed to be the strongest open model built outside China. It was trained on 4,000 Nvidia Grace Blackwell GPUs in Mistral’s European data centers and is being previewed to developers, cybersecurity teams and governments before wider release. — If sustained, this marks an open‑model arms race outside China that affects geopolitics, commercial AI supply chains, and the distribution of advanced compute resources.
