About
FastVideo FastWan2.2-TI2V-5B-FullAttn-Diffusers Model Online Demo You can try our models here！ Introduction We're excited to introduce the FastWan2.2 series—a new line of models finetuned with our novel Sparse-distill strategy. This approach jointly integrates DMD and VSA in a single training process, combining the benefits of both distillation to shorten diffusion steps and sparse attention to reduce attention computations, enabling even faster video generation. FastWan2.2-TI2V-5B-Full-Diffusers is built upon Wan-AI/Wan2.2-TI2V-5B-Diffusers. It supports efficient 3-step inference and produces high-quality videos at 121×704×1280 resolution. For training, we used simulated forward for the generator model, making the process data-free. The current FastWan2.2-TI2V-5B-Full-Diffusers model is trained using only DMD. Model Overview - 3-step inference is supported. - Our model is trained on 121×704×1280 resolution, but it supports generating videos with any resolution.(quality may degrade) - Finetuning and inference scripts are available in the FastVideo repository: - 1 Node/GPU debugging finetuning script - Slurm training example script - Inference script - Try it out on FastVideo — we support a wide range of GPUs from H100 to 4090, and also support Mac users! Training Infrastructure Training was conducted on 8 nodes with 64 H200 GPUs in total, using a global batch size = 64, and training runs for 3000 steps (~12 hours) If you use the FastWan2.2-TI2V-5B-FullAttn-Diffusers model for your research, please cite our paper:

Using it via the API
Once AxForge deploys fastwan2-2-ti2v-fullattn for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (fastwan2-2-ti2v-fullattn below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/videos/generations \
-H "Authorization: Bearer $AXFORGE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"fastwan2-2-ti2v-fullattn","prompt":"a drone shot over a forest"}'
