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 — Mistral AI
Mistral Medium 3.5 is a dense 128B-parameter model from Mistral AI, released on April 28, 2026, that combines instruction-following, reasoning and coding in a single set of weights, with image input and configurable reasoning effort. Mistral made it the default model in Le Chat and Mistral Vibe.
Model B — Stability AI
Stable Audio 3.0 Large is an audio generation model from Stability AI, released on May 20, 2026 and served through its API, which Stability AI describes as its most advanced audio model. It generates music and sound of up to about six minutes in 44.1 kHz stereo and supports audio-to-audio and inpainting; Stability AI says it was trained on licensed data. It is also available for self-hosting in enterprise deployments.

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.
