|---|---|---|---|
| BF16 / FP16 (uncompressed) | 16.6 GB | 20.3 GB all in VRAM 29.5 GB | 22.7 GB all in VRAM 31.9 GB |
| FP8 (half size, near-lossless) | 8.5 GB | 12.2 GB all in VRAM 21.3 GB | 14.6 GB all in VRAM 23.8 GB |
| GGUF Q8_0 (similar to FP8) | 8.9 GB | 12.6 GB all in VRAM 21.7 GB | 15.0 GB all in VRAM 24.2 GB |
| GGUF Q4_K_S (popular low-VRAM choice) | 5.0 GB | 9.2 GB all in VRAM 17.8 GB | 11.1 GB all in VRAM 20.3 GB |
Bold = VRAM needed when ComfyUI swaps the text encoder and the model. "All in VRAM" = keeping both loaded. Text encoder assumed at FP8. Official: minimum 14 GB (with model offloading) (measured with the official implementation).
