How to run it

Use Diffusers or ComfyUI at INT8 / fp8. The big text encoder is loaded to encode your prompt, then offloaded before generation, which is why peak VRAM stays near the backbone size rather than the sum of every file.

FAQ

Can AMD Ryzen AI Halo (128GB) run CogVideoX-5B?

Yes. CogVideoX-5B runs on AMD Ryzen AI Halo (128GB) at INT8 / fp8 (~16 GB of ~96 GB usable).

How much VRAM does CogVideoX-5B need?

AMD Ryzen AI Halo (128GB) has room to spare. At INT8 / fp8 the realistic peak is ~16 GB of VRAM, versus ~26 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~5 GB, much slower.

What do I use to run CogVideoX-5B locally?

CogVideoX-5B runs in Diffusers or ComfyUI. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
