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 — Aleph Alpha
Kolibri is a mixture-of-experts reasoning model from Aleph Alpha for German and English, released on October 3, 2026 and built for public administration and industry, with deployment on customer-controlled infrastructure. It supports a reasoning mode and tool calling.

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.
