🎉 **Recommended · VEO 3.1 Official channel now open · Very low pricing · More stable** — APIYI's official-proxy channel for AIStudio's VEO 3.1 models is now open: `veo-3.1-fast-generate-preview` **\$0.3/req**, `veo-3.1-generate-preview` **\$1.2/req**, per-request billing, flexible 4/6/8 sec durations, 720p / 1080p / 4k tiers at the same price, native synchronized audio.

💡 **Why we recommend it**: The official-proxy channel **connects directly to Google AI Studio's official API**, sitting closer to upstream at the protocol level than the [VEO 3.1 (Reverse)](/en/api-capabilities/veo/overview) channel — **fewer wobbles, higher availability**. Pricing starts at \$0.3/req and **saves 62-68%** vs Google's own 8s 1080p tier. **Default group + per-request billing just works** — existing Tokens drop in without config changes.
