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 — Microsoft Research
Phi-4-reasoning-vision-15B is a 15B-parameter open-weight vision-language reasoning model from Microsoft, released on March 4, 2026 under the MIT licence. It takes text and image input, is trained mainly on English, and has a 16,384-token context length.

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.
