This guy is a genius; for those who don’t know he also brought us ControlNet.

This is the first decent video generation model that runs on consumer hardware. Big deal and I expect ControlNet pose support soon too.

He also brought us IC-Light! I wonder why he's still contributing to open source... Surely all the big companies have made him huge offers. He's so talented

I think he is working on his Ph.D. at Stanford. I assume whatever offers he has haven't been attractive enough to abandon that, whether he’ll still be doing open work or get sucked into the bowels of some proprietary corporate behemoth afterwards remains to be seen, but I suspect he won't have trouble monetizing his skills either way.

I haven't bothered with video gen because I'm too impatient but isn't Wan pretty good too on regular hardware?

Wan 2.1 (and Hunyuan and LTXV, in descending ordee of overall video quality but each has unique strengths) work well—but slow, except LTXV—for short (single digit seconds at their usual frame rates — 16 for WAN, 24 for LXTV, I forget for Hunyuan) videos on consumer hardware. But this blows them entirely out of the water on the length it can handle, so if it does so with coherence and quality across general prompts (especially if it is competitive with WAN and Hunyuan on trainability for concepts it may not handle normally) it is potentially a radical game changer.

For completeness, I should note I'm talking about the 14B i2v and t2v WAN 2.1 models; there are others in the family, notably a set of 1.3B models that are presumably much faster, but I haven't worked with them as much

LTX-Video isn't quite the same quality as Wan, but the new distilled 0.9.6 version is pretty good and screamingly fast.

Wan 2.1 is solid but you start to get pretty bad continuity / drift issues when genning more than 81 frames (approx 5 seconds of video) whereas FramePack lets you generate 1+ minute.
