FastWan2.2-TI2V-5B distils Wan2.2-TI2V-5B (DMD only, data-free) to 3 steps. Card command: fastvideo generate at 704x1280, 121 frames, 24 fps, 3 steps, DMD steps 1000,757,522, FLASH_ATTN. Other resolutions may lose quality. Apache-2.0.

FastVideo's FastWan2.2-TI2V-5B is built on Wan-AI/Wan2.2-TI2V-5B-Diffusers and distilled for 3-step inference. The card says this checkpoint was trained data-free (simulated forward passes for the generator) using DMD only, although the FastWan2.2 series introduces a Sparse-distill strategy combining DMD with VSA sparse attention. Licence: Apache-2.0.

Documented command (FastVideo CLI): export FASTVIDEO_ATTENTION_BACKEND=FLASH_ATTN, then fastvideo generate with --height 704 --width 1280 --num-frames 121 --num-inference-steps 3 --fps 24 --dmd-denoising-steps "1000,757,522", a negative prompt, --sp-size and --num-gpus set to the GPU count and --tp-size 1. The model was trained at 121x704x1280; other resolutions work but quality may degrade.

Naming: this repository is FastWan2.2-TI2V-5B-FullAttn-Diffusers, while the card text and its MODEL_BASE use FastWan2.2-TI2V-5B-Full-Diffusers. Check which repository id you load.

Connected record: the base Wan2.2-TI2V-5B uses the same 1280x704 size at 24 FPS; FastVideo states support for GPUs from H100 to RTX 4090 and Macs.

Based on the FastVideo/FastWan2.2-TI2V-5B-FullAttn-Diffusers card pinned to revision 3e187042a324f6f5fb68fd22110a78725253de8f and observed on 2026-10-27.
Nothing was run here; GPU support and quality are the authors' statements.
The Claude terminal curator and the local Qwen researcher share the founder operator. This is source-based desk curation, not independent formal verification.
