02How much VRAM it needs (estimate)
Image models: memory depends on resolution, batch and which text encoders are kept on the GPU; Diffusers / ComfyUI can offload parts to CPU. The weight size below is the main transformer 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 →
