wavespeed-ai/wan-2.1/t2v-480p-lora

wan-2.1/t2v-480p-lora is an open-source AI video generation model developed by Alibaba Cloud, designed for text-to-video tasks. It incorporates Low-Rank Adaptation (LoRA) techniques, enabling efficient fine-tuning of pre-trained models to generate videos with specified effects from reference images. The 14-billion-parameter professional version excels in generating complex motions and simulating physical dynamics, delivering exceptional performance.

Built upon a causal 3D Variational Autoencoder (VAE) and Video Diffusion Transformer architecture, wan-2.1/t2v-480p-lora efficiently models spatiotemporal dependencies. In the authoritative VBench evaluation, the 14B version achieved a leading score of 86.22%, surpassing models like Sora, Luma, and Pika, and securing the top position. The model is available on Wavespeed AI, providing convenient access for developers.

Key Features

• LoRA-Enhanced Adaptability: Incorporates Low-Rank Adaptation to enable efficient fine-tuning, allowing the model to adapt to specific tasks or styles with fewer trainable parameters and reduced GPU memory usage.
• High-Quality 480p Video Generation: Capable of producing visually appealing 480p videos from text prompts, maintaining clarity and motion consistency.
• Efficient Performance on Consumer-Grade GPUs: Optimized to run on widely available hardware, requiring only 8.19 GB of VRAM, and capable of generating a 5-second 480p video on an RTX 4090 in approximately 4 minutes.
• Multilingual Text Rendering: Supports the generation of videos containing both Chinese and English text, expanding its applicability across different languages and regions.

ComfyUI

wan-2.1/t2v-480p-lora is also available on ComfyUI, providing local inference capabilities through a node-based workflow, ensuring flexible and efficient image generation on your system.

Limitations

• Creative Content Focus: Designed primarily for creative video synthesis; not intended for generating factually accurate or reliable content.
• Potential Biases: As with any data-driven model, outputs may reflect biases present in the training data.
• Input Sensitivity: The quality and consistency of generated videos depend significantly on the quality of the input text; subtle variations may lead to output variability.
• Resolution Constraint: Currently optimized for 480p video generation; higher resolutions may not be supported or may result in reduced stability.

Out-of-Scope Use

The model and its derivatives may not be used in any way that violates applicable national, federal, state, local, or international law or regulation, including but not limited to:

• Exploiting, harming, or attempting to exploit or harm minors, including solicitation, creation, acquisition, or dissemination of child exploitative content.
• Generating or disseminating verifiably false information with the intent to harm others.
• Creating or distributing personal identifiable information that could be used to harm an individual.
• Harassing, abusing, threatening, stalking, or bullying individuals or groups.
• Producing non-consensual nudity or illegal pornographic content.
• Making fully automated decisions that adversely affect an individual’s legal rights or create binding obligations.
• Facilitating large-scale disinformation campaigns.
