How to use ltx-2.5-22b-distilled-transformer-bf16.safetensors
- Download the file from HuggingFace.
- Place it in ComfyUI/models/checkpoints/ inside your ComfyUI directory.
- Restart ComfyUI (or refresh the model list from the menu).
- Load a compatible workflow — see below.

ComfyUI says it can't find ltx-2.5-22b-distilled-transformer-bf16.safetensors?
Some published workflow JSONs reference this file under a custom subdirectory. If ComfyUI shows a "cannot find model" error and your workflow references one of these path-prefixed variants:
- diffusion_models/ltx-2.5-22b-distilled-transformer-bf16.safetensors
The prefix before the slash or backslash is a subdirectory the workflow author used. The actual file is the same ltx-2.5-22b-distilled-transformer-bf16.safetensors — you have two fixes:
- Create the matching subdirectory inside ComfyUI/models/checkpoints/ and place the file there. Example: if the workflow references diffusion_models/ltx-2.5-22b-distilled-transformer-bf16.safetensors, create the corresponding subfolder under ComfyUI/models/checkpoints/ and put ltx-2.5-22b-distilled-transformer-bf16.safetensors inside it.
- Or open the workflow JSON in a text editor and replace the prefixed string with just ltx-2.5-22b-distilled-transformer-bf16.safetensors. ComfyUI then resolves it directly from ComfyUI/models/checkpoints/.
On Windows the separator is \, on macOS/Linux it is / — they refer to the same nested folder regardless of platform.
Common issues
ComfyUI doesn't see the file after I downloaded it▼
Make sure the file is in ComfyUI/models/checkpoints/ (not a subfolder). Restart ComfyUI fully — the menu refresh sometimes misses new files. Filename must match exactly: ltx-2.5-22b-distilled-transformer-bf16.safetensors.
CUDA out of memory error when loading the model▼
ltx-2.5-22b-distilled-transformer-bf16.safetensors needs ~32GB VRAM minimum. If you're hitting OOM: • Enable Sequential Offloading in ComfyUI settings • Lower the resolution (768×512 instead of 1280×704) — both dimensions must be divisible by 32 • Reduce frame count (65 frames instead of 161) — must be 8n+1 • Use a smaller variant — see Related models below.
What CFG and step count should I use?▼
Distilled models work best with CFG=1 and 8 sampling steps. Higher CFG or more steps with a distilled checkpoint produces over-saturated output and wastes time.
