02How much VRAM it needs (estimate)
Video models: memory grows with resolution and clip length; official repos usually list a tested GPU in the card. Weights below are the main model only.
No estimate: the official metadata does not give a parameter count. Check the model card for tested hardware.
Bits per weight: BF16 16, FP8 8.5, 4-bit 4.85. “Fits” = total ≤ 90% of memory; Mac GPU can use ~2/3 of unified memory (≤36GB) or ~3/4 (larger). For MoE, all experts must be in memory, so size by total parameters. Method →
03How to run it
Only runtimes the publisher or the runtime’s official library names for this model.
The official card does not name a runtime; see the repository.
