Wan2.2

Method overview: Wan2.2 switches a high-noise expert early in denoising and a low-noise expert later.

Alibaba Tongyi Lab's Wan2.2 family: verified TI2V 5B at 1280×704 / 121 frames / 24 fps, plus pending A14B T2V and I2V MoE routes.

Wan2.2 is Alibaba Tongyi Lab's next Wan generation — tracked separately from Wan2.1 because upstream versions the code and checkpoints on their own. This catalog card binds three Apache-2.0 Hugging Face lines: T2V A14B (MoE text-to-video), I2V A14B (MoE image-to-video), and TI2V 5B (dense text+image-to-video). Only the 5B route has a recorded demo and runner artifact in this repository.

The official paper is still Wan: Open and Advanced Large-Scale Video Generative Models. Code and weights live at Wan-Video/Wan2.2 and Wan-AI. The project site is wan.video. The catalog still points the project field at the HuMo page — that is a Wan-derived neighbor, not this family. Aliases wan-2p2 and wan2p2 resolve here.

What it is for

Start on wan2.2-ti2v-5b when you want a checkpoint-backed clip. The recorded contract is 1280×704 (or 704×1280), 121 frames, 24 fps, 50 UniPC steps, guidance 5.0, flow-shift 5.0, writing wan2.2-ti2v-5b-1280x704-121f.mp4. Prompt is required; an image switches the same 5B weights from T2V to I2V. Catalog minimum for this variant is 24 GB.

Use wan2.2-t2v-a14b for the dual-expert text-to-video card and wan2.2-i2v-a14b when a still is the conditioner. Both A14B lines are integrated with in-tree pipelines, but status is still Runner parity pending — do not treat a successful launch as a verified 14B artifact.

There is no V2V route on this card. Upstream Speech-to-Video (Wan2.2-S2V-14B) and Animate (Wan2.2-Animate-14B) exist on GitHub and Hugging Face; they are not bound here. Compare general clip quality on VBench — that is a listed suite, not an ingested WorldFoundry scorecard.

Inference

Native sampling is UniPC only. The three WorldFoundry defaults:

A14B inference swaps a high-noise expert and a low-noise expert across the schedule (catalog boundaries 0.875 T2V, 0.900 I2V). Official A14B generate scripts also advertise 480p and 720p (1280×720) at ≥80 GB with --offload_model; those sizes are upstream options, not the verified WorldFoundry profile. TI2V 5B uses the high-compression Wan2.2-VAE (16×16×4). Seed is the recorded actions field (base_seed default 42 in the command builder). Prompt extension is off by default.

Running in WorldFoundry

Install the unified environment with bash scripts/setup/unified_install.sh (Python 3.11, CUDA 12.8) and stage weights locally — the runtime does not download them. The recorded launch is worldfoundry-eval run wan2.2-ti2v-5b. That profile is the verified 5B contract, not a 14B run. Pipelines are Wan2p2Pipeline (5B), Wan2p2T2VA14BPipeline, and Wan2p2I2VA14BPipeline.

Checkpoints: Wan-AI/Wan2.2-TI2V-5B, Wan-AI/Wan2.2-T2V-A14B, Wan-AI/Wan2.2-I2V-A14B (all apache-2.0, public, not gated). Family-level hardware still lists 80 GB because that is the A14B floor; the 5B verified path is the 24 GB line.
