Mistral Large 4
Europe's 1T-parameter answer, four days old and still a preview. Independent numbers put it mid-pack (AA 38, Arena 1429) despite strong vendor coding and cyber claims. Pick it for EU hosting and policy reasons, not raw capability.

What practitioners say
Enormous HN reaction (2,037 points, 1,211 comments) split down the middle. Fans like the European training run (3,800 Grace Blackwell GPUs in Mistral's own datacentres), 'basically instant responses', and that it beats Chinese models on cyber benchmarks. Critics called it 'mediocre' and months late, and oh_no noted Mistral's published GDP.pdf numbers do not line up with Artificial Analysis's independent run. simonw found reasoning 'high' barely changes output.
Caveats
- Weights are promised for 27 Oct under an as-yet-unnamed custom licence; today it is API-only. Large 3 was Apache 2.0, so do not assume the same.
- Preview pricing is confusing: list is $1.36/$4.18 but the model page was showing $0.68/$2.09 at launch with no stated end date.
- Only two reasoning settings (none/high) and HN found little difference between them.

Compare Mistral Large 4
Methodology: Score is 0 to 100 and computed, not typed: 55% independent evals (Artificial Analysis, Arena, Scale SEAL, Epoch, each scaled against its natural floor and the best score in this table, then averaged), 15% blended price on a fixed log scale ($0.05 per million is 100, $60 is 0), 15% practitioner sentiment from Signals and community threads, 15% operational fit (context window, open weights). A missing component drops out and the rest are reweighted. A model with no independent eval yet is provisional and ranks below every measured one. Within three points is a tie. Vendor-published figures are labelled and never counted.
