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.
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
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.
100%. I don't think I've ever even come across an I2V model that didn't require at least a positive prompt. Some people get around it by integrating a vision LLM into their ComfyUI workflows however.
Wow, the examples are fairly impressive and the resources used to create them are practically trivial. Seems like inference can be run on previous generation consumer hardware. I'd like to see throughput stats for inference on a 5090 too at some point.
That's a certified bop! ;) You should get elybeatmaker to do a remix!

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

With static images, we always look for eyes.
With video, we always look for dancing.
It can leave LLMs behind...
'Cause LLMs don't dance, and if they don't dance, well, they're no friends of mine.
