How much does the Wan-AI/wan2.7-i2v API cost?

On FastInfra, Wan-AI/wan2.7-i2v costs $0/1M input, $0/1M output tokens ($0 per second of video). Billing is per token used, with no subscription.

Is Wan-AI/wan2.7-i2v compatible with the OpenAI SDK?

Video models use the same FastInfra API key and base URL (https://api.fastinfra.ai/v1). List SKUs with GET https://api.fastinfra.ai/v1/videos/models, submit with POST https://api.fastinfra.ai/v1/videos (HTTP 202), poll GET https://api.fastinfra.ai/v1/videos/{id} until status is completed. They do not work on POST https://api.fastinfra.ai/v1/chat/completions.

Can I call Wan-AI/wan2.7-i2v on POST /chat/completions?

No. Wan-AI/wan2.7-i2v is a video model. Use GET https://api.fastinfra.ai/v1/videos/models to confirm the id, POST https://api.fastinfra.ai/v1/videos with "model": "Wan-AI/wan2.7-i2v", then poll GET https://api.fastinfra.ai/v1/videos/{id}.

I asked for Wan 2.2 — why doesn't it work?

Wan is available on FastInfra through the video job API, not chat. Call GET https://api.fastinfra.ai/v1/videos/models and use the exact Wan video id listed there (often alibaba/wan-2.6 or newer). Names like "wan-2.2" only work if that exact id appears in the list. See the docs section "Alibaba Wan" for the full flow.

How does routing work for Wan-AI/wan2.7-i2v?

Wan-AI/wan2.7-i2v is available on 1 route(s): route-03. Requests use route-03 by default (lowest cost). FastInfra fails over automatically if a route is unavailable.
