Veo 3.1 API
What is Veo 3.1
Veo 3.1 is Google's video generation model, available through varg's gateway. varg's own catalog doesn't carry a description field for this route beyond the model name — treat capability claims about it as something to verify against Google's own Veo documentation rather than assuming feature parity with other models in this list.
Veo 3.1 via varg vs. calling Google directly
Going direct to Google means a separate account and API relationship, billed and managed independently of any other model you use. Through varg, Veo 3.1 shares the same gateway, credit balance, and 30-day generation cache as Kling, Sora, Wan, and the rest of the catalog.
Pricing
Estimated cost via varg: $3.36 per generation, billed per second of output — longer clips cost more. Two lower-cost variants exist in the same family: Veo 3.1 Fast ($0.84 estimated) and Veo 3.1 Lite ($0.42 estimated).
Code example
curl https://api.varg.ai/v2/tools/video \
-H "Authorization: Bearer $VARG_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "google:veo_3_1",
"prompt": "aerial shot of a coastal highway at dawn"
}'
See docs.varg.ai for the confirmed request/response shape.
When to use Veo 3.1 vs. other video models
If budget is the main constraint, Veo 3.1 Lite at an estimated $0.42/generation is the cheapest Google route in varg's catalog — worth testing before defaulting to the full Veo 3.1 price point. If you specifically need Google's model behavior rather than Kling's or Sora's, stick with this family and pick the tier (full / Fast / Lite) that matches your budget. Compare against Sora 2 ($1.05 flat) if predictable flat pricing matters more than per-second billing.
