What is Veo 3.1 Official
Official API forwarding (vs reverse engineering) provides direct access to Google Veo 3.1 with transparent per-generation pricing and production-grade reliability.
Official vs Reverse
Official forwarding rides on Google's official infrastructure — stable, not rate-limited by reverse-engineering quirks. Recommended for any production workload.
Per-Generation Billing
Fast model $0.30/call, standard model $1.20/call — independent of duration and resolution. Failed / cancelled tasks are free.
Native Audio
Veo 3 / 3.1 is a native audio-aware video model. Write the audio intent into your prompt — no extra generateAudio parameter needed.
Image-to-Video
Drive camera motion from one reference image (input_reference). Same price as text-to-video — pick whichever fits the shot.
Why Choose Official
Official API forwarding gives you stability, fidelity, and commercial usability that reverse-engineered access can't match.
Models & Pricing
Two models, per-call pricing, success-only billing.

veo-3.1-generate-preview
Standard model — $1.20 per call. Tighter texture and physical consistency for finals.
