Wan2.2 is an open and advanced large-scale video generative model that builds on the foundation of Wan2.1 with notable improvements in generation quality and model capability. The upgrade is driven by key technical innovations including the Mixture-of-Experts (MoE) architecture, upgraded training data, and high-compression VAE technology.
Wan2.2 introduces a Mixture-of-Experts (MoE) architecture into video diffusion models, which separates the denoising process across timesteps with specialized powerful expert models. This approach enlarges the overall model capacity while maintaining the same computational cost, making it one of the fastest 720P@24fps models currently available. Wan 2.2 nsfw supports both text-to-video and image-to-video generation at 720P resolution with 24fps and can run on consumer-grade graphics cards like the RTX 4090. The TI2V-5B model, built with the advanced Wan2.2-VAE, achieves a compression ratio of 16×16×4, enabling efficient high-definition hybrid text-image-to-video generation. This technical foundation allows the model to serve both industrial and academic sectors simultaneously, with the capability to generate videos at 480P and 720P resolutions depending on the specific model variant used.
Compared to Wan2.1, Wan2.2 is trained on a significantly larger dataset, with 65.6% more images and 83.2% more videos. This expansion notably enhances wan 2.2 nsfw's generalization across multiple dimensions such as motions, semantics, and aesthetics, achieving top performance among both open-sourced and closed-sourced models. The model incorporates meticulously curated aesthetic data with detailed labels for lighting, composition, contrast, color tone, and more, allowing for more precise and controllable cinematic style generation. This facilitates the creation of videos with customizable aesthetic preferences. The complex motion generation capabilities are a direct result of this expanded training data, enabling the model to handle a wide variety of motion types and semantic concepts. The model's ability to generalize across these dimensions makes it suitable for diverse video generation tasks, from simple object movements to complex scene transitions.
Wan2.2 offers a comprehensive suite of video generation capabilities including text-to-video, image-to-video, text-image-to-video, speech-to-video, and character animation. Each model variant is designed for specific use cases and has different hardware requirements.
Wan2.2 provides multiple model variants for different generation tasks. The T2V-A14B model handles text-to-video generation at 480P and 720P resolutions. The I2V-A14B model performs image-to-video generation at the same resolutions. The TI2V-5B model offers high-compression VAE with both text-to-video and image-to-video capabilities at 720P. The S2V-14B model enables audio-driven cinematic video generation at 480P and 720P. The Animate-14B model handles character animation and replacement with holistic movement and expression replication. Each model has specific hardware requirements, with the TI2V-5B model capable of running on GPUs with at least 24GB VRAM such as the RTX 4090, while the larger 14B models typically require 80GB VRAM for single-GPU inference. Multi-GPU inference using FSDP and DeepSpeed Ulysses is supported for all model variants.
Wan2.2 supports prompt extension to enrich details in generated videos and enhance video quality. Two methods are available for prompt extension: using the Dashscope API or using a local Qwen model. For text-to-video tasks, users can choose from Qwen2.5-14B-Instruct, Qwen2.5-7B-Instruct, or Qwen2.5-3B-Instruct models, with larger models generally providing better extension results but requiring more GPU memory. For image-to-video tasks, Qwen2.5-VL-7B-Instruct and Qwen2.5-VL-3B-Instruct models are available. Wan 2.2 nsfw can also generate videos solely from input images without any text prompt, using prompt extension to generate prompts from the image. The generation process supports various parameters including resolution, frame rate, guidance scale, and number of inference steps, giving users fine-grained control over the output. The model has been integrated into Diffusers, ComfyUI, and other popular frameworks.
Wan2.2 is available as an open-source model with weights and inference code released to the public. Wan 2.2 nsfw can be accessed through multiple platforms and integrated into various workflows.
Wan2.2 model weights are available for download through multiple platforms including Hugging Face and ModelScope. The available models include T2V-A14B for text-to-video, I2V-A14B for image-to-video, TI2V-5B for high-compression VAE with text-to-video and image-to-video, S2V-14B for speech-to-video, and Animate-14B for character animation and replacement. Users can download models using huggingface-cli or modelscope-cli tools. The inference code is provided in the official GitHub repository, along with comprehensive documentation and user guides in both Chinese and English. Wan 2.2 nsfw has been integrated into various community tools and frameworks including Diffusers, ComfyUI, and FastVideo, making it accessible to users with different technical backgrounds and workflow preferences.
Wan2.2 has been integrated into numerous community tools and frameworks. Diffusers supports T2V-A14B, I2V-A14B, and TI2V-5B models. ComfyUI integration is available through both official channels and community implementations like Kijai's ComfyUI WanVideoWrapper. FastVideo includes distilled Wan models with sparse attention that significantly speed up inference time. Cache-dit offers fully cache acceleration support for Wan2.2 MoE with DBCache, TaylorSeer, and Cache CFG. DiffSynth-Studio provides comprehensive support including low-GPU-memory layer-by-layer offload, FP8 quantization, sequence parallelism, LoRA training, and full training. Community projects like Prompt Relay, Helios, LightX2V, HuMo, and TalkVerse build upon Wan2.2 to provide additional capabilities such as temporal control, minute-scale video synthesis, and audio-driven human video generation.
Wan2.2 offers multiple model configurations with different hardware requirements and performance characteristics. Understanding these configurations helps users select the appropriate setup for their needs and available resources.
Wan2.2 supports both single-GPU and multi-GPU inference configurations. For single-GPU inference, the TI2V-5B model can run on GPUs with at least 24GB VRAM such as the RTX 4090, using options like --offload_model True, --convert_model_dtype, and --t5_cpu to reduce memory usage. The larger 14B models require at least 80GB VRAM for single-GPU inference. Multi-GPU inference uses PyTorch FSDP and DeepSpeed Ulysses to accelerate processing, with configurations supporting up to 8 GPUs. The distributed testing utilizes built-in FSDP and Ulysses implementations, with FlashAttention3 deployed on Hopper architecture GPUs. Performance testing shows results in the format of total time in seconds and peak GPU memory in GB, with tests run without the prompt extension flag and reported as averages of multiple samples after warm-up phase.
Wan2.2 supports two methods for prompt extension to enhance video quality. The Dashscope API method requires users to apply for a dashscope.api_key in advance and configure the environment variable DASH_API_KEY. For users of Alibaba Cloud's international site, the environment variable DASH_API_URL must be set to 'https://dashscope-intl.aliyuncs.com/api/v1'. The Dashscope API uses the qwen-plus model for text-to-video tasks and qwen-vl-max for image-to-video tasks. The local model method uses Qwen models from HuggingFace, with users able to choose from Qwen2.5-14B-Instruct, Qwen2.5-7B-Instruct, or Qwen2.5-3B-Instruct for text-to-video, and Qwen2.5-VL-7B-Instruct or Qwen2.5-VL-3B-Instruct for image-to-video. Wan 2.2 nsfw used for extension can be modified with the --prompt_extend_model parameter, allowing specification of either a local model path or a Hugging Face model.
When working with Wan2.2, several practical considerations can help optimize the generation process and avoid common issues. These notes cover memory management, model selection, and integration best practices.
Memory management is crucial when running Wan2.2 models, especially on consumer-grade hardware. For the TI2V-5B model, using --offload_model True, --convert_model_dtype, and --t5_cpu options can reduce GPU memory usage to run on GPUs with at least 24GB VRAM. For larger 14B models, single-GPU inference requires at least 80GB VRAM, but multi-GPU configurations using FSDP and DeepSpeed Ulysses can distribute the memory load across multiple GPUs. The --convert_model_dtype flag converts model parameter types to config.param_dtype, which can help reduce memory usage. Users experiencing out-of-memory issues should enable offloading and consider using lower precision formats. Wan 2.2 nsfw supports FP8 quantization through DiffSynth-Studio for further memory optimization. For the Wan-Animate model, users should note that LoRA models trained on Wan2.2 are not recommended as weight changes during training may lead to unexpected behavior.
Wan2.2 has been integrated into multiple frameworks and tools, each with specific considerations. For Diffusers integration, users can use the WanAnimatePipeline for character animation and replacement tasks, with support for both animation and replacement modes. The ComfyUI integration allows for visual workflow creation, with community implementations like Kijai's ComfyUI WanVideoWrapper offering cutting-edge optimizations and hot research features. For the Speech-to-Video task, the model can generate videos from audio input combined with reference images and optional text prompts, with the --num_clip parameter controlling the number of video clips generated for quick preview. The --pose_video parameter enables pose-driven generation, allowing the model to follow specific pose sequences while generating videos synchronized with audio input. Users should also consider that the TI2V-5B model supports 720P video generation at 24 FPS, with the 720P resolution being 1280x704 or 704x1280.
