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 — AI21 Labs
Jamba2 Mini is an open-source model in AI21 Labs’ Jamba2 family, released on January 8, 2026 alongside Jamba2 3B. It is built on the SSM-Transformer architecture and aimed at grounded, steerable enterprise question answering without the overhead of a reasoning model.

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.
