HY Can I run HunyuanVideo on Nvidia GeForce RTX 3090 (24GB)?
Yes. HunyuanVideo runs on Nvidia GeForce RTX 3090 (24GB) at Q4 GGUF (~16 GB of ~23 GB usable).
Runs at Q4 GGUF using ~16 GB of ~23 GB usable.

How to run it
Use ComfyUI at Q4 GGUF. 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 Nvidia GeForce RTX 3090 (24GB) run HunyuanVideo?
Yes. HunyuanVideo runs on Nvidia GeForce RTX 3090 (24GB) at Q4 GGUF (~16 GB of ~23 GB usable).
How much VRAM does HunyuanVideo need?
Nvidia GeForce RTX 3090 (24GB) has room to spare. At Q4 GGUF the realistic peak is ~16 GB of VRAM, versus ~60 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~8 GB, much slower.
What do I use to run HunyuanVideo locally?
HunyuanVideo runs in ComfyUI. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
