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 4 is a mixture-of-experts model from Mistral AI with 1.05T total and 52B active parameters, first offered as an API preview on October 6, 2026; Mistral has since published its weights on Hugging Face. It takes text and image input, returns text, and supports function calling and configurable reasoning effort.
Model B — Meta
Muse Spark Open is an open-weight mixture-of-experts model from Meta, released on October 15, 2026, with 816B total and 42B active parameters. It takes text, image, video and audio input and returns text. Meta's own Model API does not serve it: it is self-hosted or run through hosted providers.

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.
