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 — Swiss AI Initiative
Apertus 1.5 70B is the 70B-parameter member of Apertus 1.5, the fully open multilingual model family from the Swiss AI Initiative (ETH Zurich, EPFL and CSCS), released on July 24, 2026. It was continued-pretrained from Apertus 1.0, takes image, audio and text input, generates text, and has an optional thinking mode.
Model B — Alibaba
Qwen3.8-27B is an open-weight 27-billion-parameter dense native vision-language model that understands images and videos, with thinking on by default and adjustable reasoning effort. It is released under Apache 2.0.

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.
