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 — Institute of Foundation Models (MBZUAI)
Jais 3 is a family of Arabic-centric open models from MBZUAI's Institute of Foundation Models and Inception42, released on October 15, 2026 in sizes from 0.9B to 375B parameters and built on IFM's K2 Horizon models. The largest, Jais-3-375B-A23B, is made for Arabic and English assistant and agentic work, including reasoning and tool use.
Model B — Moonshot AI
Kimi K3.1 Pro is the first model of Moonshot AI's K3.1 series, launched on October 23, 2026 with a 1M-token context window and a faster Highspeed variant. Moonshot says its full weights will be released by November 4, 2026; until then it is offered only through Kimi's apps and API.

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.
