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 — Reflection AI
Beam is Reflection AI's first open-weight model, a 501B-parameter sparse mixture-of-experts model with 23B active parameters, built for coding, reasoning and agentic work. Announced on October 5, 2026, its weights were released on Hugging Face under Apache 2.0; it takes and returns text only.

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.
