Wan 2.5 API
What is Wan 2.5
When Kling or Sora pricing doesn't fit the budget for a high-volume job — say, generating dozens of short product variants — Wan 2.5 is varg's catalog note for 'strong text-to-video at a competitive price.' It's Alibaba's model, routed via fal.ai.
Wan 2.5 via varg vs. calling fal.ai directly
Direct fal.ai access means a separate account and no shared caching with anything else you generate. Through varg, Wan 2.5 sits on the same gateway and credit balance as Kling, Sora, and Veo, with identical prompts cached for 30 days.
Pricing
Estimated cost via varg: $1.58 per generation, billed per second of output. A preview variant, Wan 2.5 Preview, carries the same estimated cost but adds lip-sync support — worth checking if your job needs that specifically.
Code example
curl https://api.varg.ai/v2/tools/video \
-H "Authorization: Bearer $VARG_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "fal:wan_2.5/t2v",
"prompt": "close-up of coffee being poured into a ceramic mug, steam rising"
}'
See docs.varg.ai for the confirmed request/response shape.
When to use Wan 2.5 vs. other video models
Use Wan 2.5 for a mid-priced text-to-video option when you don't specifically need Kling's or Sora's look. Use Wan 2.5 Preview instead of the base model if you need lip-sync support at the same estimated cost. Use Kling v3 Standard ($2.21 estimated) if you want to stay in the Kling ecosystem at a comparable price point, or Sora 2 ($1.05 flat) if predictable flat billing matters more than per-second cost.
