AnimeGen T2V is a text-to-video generation model specialized for Japanese anime-style video generation.
AnimeGen T2V was developed by AIdeaLab, Inc. as part of its effort to build high-quality generative AI models for animation and video production. The model was developed with support from GENIAC — Generative AI Accelerator Challenge, a Japanese government-backed project led by the Ministry of Economy, Trade and Industry of Japan (METI) and the New Energy and Industrial Technology Development Organization (NEDO), whose goal is to strengthen domestic capabilities in generative AI development.
AnimeGen T2V is based on Wan 2.2 T2V A14B and further trained to improve anime-style motion, character rendering, color composition, and visual consistency for animation-oriented use cases.
The model is released under the Apache-2.0 license.
How to Get Started
Requirements
AnimeGen T2V is intended to be used in a Python environment with PyTorch and Diffusers.
A high-end NVIDIA GPU is recommended. For local inference, an NVIDIA RTX 4090 or higher is recommended. Larger VRAM GPUs may provide a more stable experience, especially for longer videos or higher resolutions.

Model Details
Model Description
AnimeGen T2V is a text-to-video model fine-tuned from Alibaba’s Wan 2.2 video generation model. By building on Wan 2.2, AnimeGen T2V benefits from the existing Wan ecosystem, including inference pipelines, model conversion tools, and deployment workflows.
The goal of AnimeGen T2V is to make anime-style video generation more accessible for creators, researchers, and developers. It is intended for tasks such as visual prototyping, animation previsualization, motion concept exploration, and short-form anime-style video generation.
Developed by: AIdeaLab, Inc.
Funded by: METI, NEDO, and AIdeaLab, Inc.
Base model: Wan-AI/Wan2.2-T2V-A14B
Model type: Diffusion Transformer
Training objective: Flow Matching
Primary modality: Text-to-video
Primary style domain: Japanese anime-style video
Language: English prompts are recommended
License: Apache-2.0
Intended Uses
Direct Use
AnimeGen T2V can be used for:
anime-style text-to-video generation
animation previsualization
movie storyboard and video storyboard prototyping
visual concept exploration
character motion studies
background, composition, and atmosphere exploration
short-form anime-style content creation
research and experimentation in video generation
The model is especially suitable for creators and researchers who want to quickly explore anime-style moving images from text prompts.
Research and Development Use
AnimeGen T2V may also be useful for:
studying anime-style video generation
evaluating temporal consistency in generated video
testing text-to-video workflows
building animation production support tools
developing controllable video generation pipelines
Out-of-Scope Uses
The model must not be used for:
creating deepfakes of real people
impersonation or identity deception
generating misleading political, journalistic, or documentary-style content
harassment, defamation, or non-consensual depictions
creating sexualized content involving minors or minor-looking characters
generating illegal, harmful, or abusive content
falsely presenting generated content as real footage
Users are responsible for ensuring that their use of the model complies with applicable laws, platform policies, and ethical guidelines.
Bias, Risks, and Limitations
AnimeGen T2V is optimized for anime-style visual expression. It is not intended to generate photorealistic video.
Known limitations include:
limited suitability for photorealistic or live-action video generation
possible instability in complex character motion
possible inconsistencies in hands, fingers, eyes, accessories, and fine details
possible identity drift across frames
possible temporal flickering
difficulty with long or highly detailed action sequences
limited understanding of highly complex physical interactions
reduced performance outside anime-style prompts
limited suitability for NSFW generation
Because this is a generative model, outputs may contain unexpected artifacts or unintended visual content. Users should review generated outputs before publication or commercial use.
Training and Development Background
AnimeGen T2V was developed by AIdeaLab as part of a broader research and development effort in Japanese text-to-video and anime-style generative AI.
AIdeaLab has worked on video generation models and related generative AI systems, including Japanese text-to-video model development and animation-oriented generation workflows. AnimeGen T2V builds on this experience and focuses specifically on improving anime-style video generation using a strong open text-to-video base model.
The model was trained using GPU compute resources provided through a KDDI GPU cluster located in Kagawa, Japan.
