MiniMax H3 Text-to-Video vs Grok Imagine Video v1.5 Text-to-Video
H3 against Grok Imagine Video 1.5.
Every value below is read from the model catalog at generation time — price and which parameters each model exposes. 7 of the 11 spec rows differ between these two. “Not exposed” means the model has no API parameter for it — it does not mean the capability is absent. Audio is the clearest case: MiniMax H3 generates sound with the clip but offers no switch to control it, while some models expose one.

Which should I use for text-to-video?
Whichever exposes the parameter you need — the table above is the honest answer. If you are iterating, use the cheaper model until the motion is right, then re-render once. If you need a specific resolution path, check the resolution row: some tiers reach it natively and others via a super-resolution pass, which is not the same thing.
