AI video models that render at 4K
Most AI video models stop at 1080p. 4K is nine times the pixels of 720p, the providers price it accordingly, and a model has to have been trained for it — which is why this list is short and why the rest of the catalogue is not on it.
These are the 12 on Musevate that will render at that size and that the router will actually accept a 4K request for. The least expensive of them is P-Video-2 Pro. Resolution is not quality: it is worth paying for when the clip will be cropped or shown large, and worth skipping when it will not.

Questions
Which AI video models render at 4K?
12 of the 80 models on Musevate do. The number is small because 4K is nine times the pixels of 720p and most models are not trained to produce it; a model that offers only 1080p is not listed here however good it is at 1080p.
Why does 4K cost more than 720p on the same model?
Because the providers charge more for it, and by roughly the pixel count: 4K is nine times the area of 720p and the rate follows. The price shown against each model here is for a five second clip at 720p, or at the smallest size it sells where it does not sell 720p, and the studio quotes the real figure for the size you pick before you spend anything.
Is a 4K model better than a 1080p one?
Not on its own. Resolution is the number of pixels, not the quality of what is in them, and a strong 1080p model routinely looks better than a weak 4K one on the same prompt. 4K matters when the clip will be cropped, punched in on, or shown on a large screen — and when it does not, you are paying nine times the pixels for a difference nobody will see.
Where do these sizes come from?
From our own catalogue — the records the studio sells from — where each model's sizes are recorded from its provider's published schema rather than from its marketing. A size is only listed if the router would actually accept a request for it — price, margin and cost cap included — so a model that publishes 4K but would be refused for it does not appear.
