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 — MiniMax
MiniMax H3 is an open-weight general-purpose video model that understands text, image, video and audio context and generates video with native stereo audio at up to 2K resolution and 15 seconds. A faster post-trained variant, MiniMax-H3-Max, is offered on the API. Its licence excludes use in the European Union, the United Kingdom, South Korea and the United States, and commercial use above US$20 million in revenue needs MiniMax’s written authorisation.
Model B — Meta
Muse Spark 1.3 is the latest version of Meta's Muse Spark model, released on September 2, 2026 and tuned for agentic workflows and coding. It takes text, image, video, audio and PDF input and returns text, with reasoning effort up to 'max'. Meta says audio input is not yet fully supported.

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.
