About Wan 2.2 Text-to-Video
TL;DRAs of September 23, 2026
Wan 2.2 Text-to-Video is a model by Alibaba (Wan) in the Video generation category. On Railwail, Wan 2.2 Text-to-Video costs $0.060 per video. Depending on the settings, the price ranges from $0.060/video to $0.12/video. Supported aspect ratios: 16:9 and 9:16.
Background
About Alibaba (Tongyi Wanxiang Lab)
Founded 1999 · Hangzhou, China
Alibaba's Tongyi Lab in Hangzhou runs the Qwen LLM family and the Wanxiang generative-media family. After Wan 2.0 (mid-2024) and Wan 2.1 (early 2025), the team released Wan 2.2 in 2025 as the next-generation open-weight video model. Wan 2.2 ships as purpose-tuned variants for Text-to-Video, Image-to-Video and Audio/A2V. Wan 2.2 Text-to-Video is the flagship pure-text-conditioned variant and replaces Wan 2.1 T2V-14B as the principal open-weight text-to-video reference for the Chinese research community. The Wan team consistently rank near the top of open-model VBench leaderboards and ship reproducible training code under a permissive Wan-series licence.
Diffusion Transformer (DiT) with 3D causal VAE; MoE-style scaling
Wan 2.2 Text-to-Video is a Diffusion Transformer operating on a 3D causal Wan-VAE latent. Wan 2.2 introduces architectural refinements over Wan 2.1: improved 3D Rotary Position Embeddings, larger attention windows, and (in the flagship) a Mixture-of-Experts feed-forward design that routes tokens to specialist experts. Text conditioning uses a Qwen-family multilingual encoder with strong Chinese-English capability. The denoiser is trained with Flow Matching on a curated multi-million-clip multilingual video corpus with synthetic dense bilingual captions. Native generation is 5 seconds at 720p / 24 fps (with 1080p extensions). The training recipe and weights are open-source on Hugging Face and GitHub under the Wan-series permissive licence, designed to enable broad commercial and research use.
Parameters
14 billion (flagship); smaller variants available
Capabilities
Open-weight text-to-video flagship at 14B parameters (smaller variants available)
Bilingual Chinese/English prompts via Qwen-based text encoder
MoE-style scaling and improved 3D RoPE in flagship variant
Permissive Wan-series licence for research and commercial use
Top-tier results on VBench among open-weight models
Active community ecosystem (LoRAs, fine-tunes, ComfyUI nodes)
Reproducible training recipe and code
Best for: open-source video pipelines, research, on-prem creative tooling, branded fine-tunes.
Training & license
Curated multi-million-clip multilingual video corpus filtered for aesthetics, motion and caption quality, with dense bilingual captions; specifics documented in Wan technical materials.
License: Open weights under an Apache-style permissive licence (Wan-series release).
Safety testing: Data-level filtering and recommended NSFW classifier for deployment; Alibaba-hosted endpoints follow Chinese CAC algorithmic-content rules.
Known limitations
Native duration 5 seconds
No native audio
High VRAM requirements for the 14B flagship
Closed leaders (Veo 3, Sora 2, Kling v3) still ahead on absolute fidelity
Resolution capped at 720p natively (1080p only in extended modes)
