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 — Xiaomi
MiMo-V2.6-Pro is a natively omnimodal sparse Mixture-of-Experts model with 1.02T total and 42B activated parameters and a 1M-token context, which Xiaomi calls its most capable MiMo model. Xiaomi released and open-sourced it under the MIT licence on September 22, 2026.
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.
