Wan 2.1 — Alibaba Cloud's video workhorse
---

Wan 2.1

### Alibaba Cloud's video model

Wan 2.1 is Alibaba Cloud's video generation model. Text-to-video and image-to-video from the same API surface, with strong motion realism and subject consistency.

Open-source heritage

### Proven community quality

Wan 2.1 is the open-source-friendly release that made Wan popular for bulk video workloads. Lower per-clip cost than Wan 2.2 or 2.7 while still delivering production-ready output.

Text-to-Video

### Cinematic generation

Generate short clips from text prompts. Wan 2.1 handles camera movement, subject consistency, and natural physics at 720p-1080p.

Image-to-Video

### Animate stills

Turn a single image into motion. Optional motion prompt for direction, speed, and intensity of the animation.

Pricing

### Cheapest Wan variant

Wan 2.1 is priced lower than Wan 2.2 / 2.7 — typically ~$0.10 per 5-second clip on ModelsLab. Ideal for high-volume workflows where cost matters.

One API Key

### No Alibaba Cloud account

Call Wan via the ModelsLab REST API. Same key works for every other video model (Kling, Seedance, Runway Aleph, Veo).

Webhooks

### Async callbacks

Pass a webhook URL — ModelsLab POSTs the MP4 to your endpoint when generation completes.

SDKs

### Python & JavaScript

Official SDKs wrap every Wan endpoint. REST + OpenAPI for autogenerated clients.

FAQ

Common questions about Wan 2.1 API — Upgraded to Wan 2.2
---

[Read the docs ](https://docs.modelslab.com)

### Is Wan 2.1 still available?

Wan 2.1 was the original open-source Wan release from Alibaba Cloud. The current production endpoint on ModelsLab is Wan 2.2 (/models/modelslab/wan-2.2-i2v), which is a direct drop-in successor — same architecture, backward-compatible prompts, improved motion coherence. Wan 2.7 is also available for multimodal workflows. Use Wan 2.2 unless you have a specific reason to target v2.1 parameters.

### What is Wan 2.2 and how does it differ from Wan 2.1?

Wan 2.2 is Alibaba Cloud's incremental upgrade over Wan 2.1 — same motion model lineage, backward-compatible prompt structure, better temporal coherence on longer clips. Most prompts that worked on 2.1 produce equal-or-better output on 2.2 without code changes.

### How much does Wan video generation API cost?

Wan 2.2 on ModelsLab is priced around $0.10 per 5-second 720p clip — typically the cheapest cinematic video model available. Transparent per-call pricing with free credits on signup.

### Wan 2.2 vs Wan 2.7 — which should I use?

Wan 2.2 is the cheapest and strongest for bulk video generation workloads. Wan 2.7 adds multimodal inputs (text-to-image + image-edit + text-to-video + image-to-video in one family) at a slightly higher per-clip price. Both run behind one ModelsLab API key.

### Can Wan 2.2 do image-to-video?

Yes. Call /models/modelslab/wan-2.2-i2v with an input image plus optional motion prompt. Returns a short animated MP4 clip.

### What's the max clip length?

Each Wan call produces 5-10 seconds. For longer sequences, generate multiple clips and stitch them at scene boundaries — a common pattern for 30-60s social video.

### Is there a free Wan API tier?

Yes. Every new ModelsLab account gets free credits — no credit card required. Use them to test Wan 2.2 against Kling, Seedance, Runway Aleph and Veo before picking a paid plan.

### Does Wan 2.2 support webhooks?

Yes. Pass a webhook URL and ModelsLab POSTs the completed MP4 URL to your endpoint when generation finishes.
