AI Model Comparison
Side-by-side comparison of pricing, context window, benchmarks, capabilities, and license. Every figure comes from the developer's own pages, last checked on ; each model's page lists its sources. A figure we could not source shows as a dash.
Model A — Mistral AI
Mistral Large 3 is an open-weight, sparse mixture-of-experts model from Mistral AI, released on December 2, 2025 under Apache 2.0, with 41B active and 675B total parameters. It accepts text and image input.

Bold green values indicate the winner on that dimension where comparison is meaningful (lower price wins; bigger context wins; more open license wins; newer date wins). Prices are the ones each developer lists today; a model it no longer prices has none.
