ComfyUI Showdown: LTX vs Hunyuan vs Cosmos - Which AI Model Reigns Supreme?

Share the workflow and the prompts so we can test on out own.

Sure. those are little complex, but I can arrange them. will update here when some will be ready with sharable links.

Very interested in a month from now when FastCache, or TeaCache, or First Block Cache, is working with Cosmos and suddenly it's not the slowest thing on the block anymore.

[@NissimsTutorials-l6g]

Very interesting... are those will work in ComfyUI as well? hope they will expedite the rendering speed, not only for Nvidia 4090. the problem is also the extra memory we need for it. lets see...

LTXV I could not tame, and Cosmos was utter garbage with a restrictive "this many, exactly, frames otherwise". Hunyuan was my winner, but it has its own issues. They are quality issues, slowness, and no way to easily extend it. I wish ltxv was more able to be tamed as it is the one I feel is the best for consumer grade hardware. Oh, go to Linux and for 3.5 minutes, 30 steps, 4090 it was either 193 frames or 209 but I forget which one. I think 209 for me for Hunyuan. In windows (even with sage and triton) it was 8.5m.

Because Cosmos take 15 minutes I will also choose Hunyuan for most of the work, but I also found Cosmos to give me better results, not always, but in most cases. the processing time is not worth it. I didn't try Hunyuan on Linux, maybe in the future when make the compute dual boot...

@@NissimsTutorials-l6g Yes, I do not like WSL so dual boot is what I do.

[@NissimsTutorials-l6g]

@@generalawareness101 yes. make sense.

I thot cosmos was 1280x704? Is it 702? I agree tho, comos has the best realistic quality but super long render times.

[@NissimsTutorials-l6g]

yes, it better to be 704 (16x multiple) but it didn't cause issue when I rendered it. I will use Cosmos only if really needed, but the alternatives are not so good as well.
