Blog · Watch/Read · (gathered 2026-10-14)

  • Simon Willison reports on the preview release of Mistral Large 4, framing it as a significant comeback for Mistral, bringing them “back to being maybe about 6 months behind the frontier.”
  • Mistral Large 4 is a massive model featuring 1 trillion parameters (49 billion active) trained on 3,800 NVIDIA Grace Blackwell GPUs, available via API preview with open weights promised by month-end.
  • The model scores 38 on Artificial Analysis, a substantial improvement over Mistral Large 3’s score of 9, placing it just behind DeepSeek 4.1 Flash.
  • It supports “none” and “high” reasoning levels, with the “high” level producing better outputs (e.g., pelican image) and surprisingly using fewer output tokens (2,717 vs 3,275).
