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 — Alibaba
Qwen3.8-Max is a native vision-language model from Alibaba’s Qwen team, which Qwen calls its flagship, a 2.4-trillion-parameter Mixture-of-Experts model with hybrid thinking (on by default) and a 1M-token context window. Its open-weight counterpart, Qwen3.8-2.4T-A95B, has 95B activated parameters.
Model B — ByteDance Seed
Seedance 2.5 (Dreamina Seedance 2.5) is ByteDance Seed's audio-video joint generation model, built for 30-second storytelling with reference control and editing. It outputs 480p to 1080p video at 24 fps, 4 to 30 seconds per generation.

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.
