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 — Upstage
Solar Pro 4 is Upstage’s flagship model, released on August 6, 2026, built for agentic use and document-based work, coding and business tasks. It supports a 512K context, up to 128K output tokens and a reasoning mode. It is available through Upstage’s console and on-premises.

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.
