“You use a VAE to compress the videos and you also need to store, typically you need to store those continuous feature on also in your storage. That's also comparable size with the videos themselves.”

Ethan He: Pipeline bug fixes drive more model gains than new algorithms
“And often I find that this is kind of boring, but like a lot of the improvements does not come from new algorithms. It comes from finding small bugs here and there in the data pipeline, in the model training pipeline. Those gave the biggest boost to the model …”
Ethan He: Falling inference costs will enable generative UIs for everything
“So I think as a inference cost come down, we are going to have generative UI for everything.”
Ethan He: Training video models costs roughly the same as medium-scale LLMs
“So surprisingly video models is like the cost is very, is comparable to language models. And obviously the largest scale is language model. Maybe like a medium scale language models.”
Ethan He: Visual intelligence in video generation models stems primarily from language models
“The visual intelligence are actually mostly coming from language. Like, these video models, especially from now, since the diffusion model technology is more mature, the, like, every time you see there, there's some improvement on these models, I would say mos…”
Ethan He: LLM Video Agents Will Orchestrate Diffusion Models and Editing Tools
“Video agents, mostly language models, they'll call these generative model, either it's a separate model or a diffusion head or whatever as tool. So this model can iteratively Refine the results or even like you generate longer content through a very long trend…”
Ethan He: Video Agents Will Reach Production-Grade Quality by Year-End
“I guess by the end of this year is this is going to be a big hit. So the inflection point will be there and the videos generated by video agents can get to like production great quality. So it can be presented and it can be distributed in, in ads.”
