Hi Google AI team,

We already use Veo 3 via Gemini/Vertex in production and want to plan an upgrade to Veo 3.1 (the version announced with up to 60s videos, clean 1080p, better temporal consistency, and multi-prompt scene transitions).

Could you please clarify the following for Veo 3.1:

  1. Availability & timeline

    • ETA for public access in AI Studio, Gemini API, and Vertex AI?

    • Is there an allowlist/preview we can join?

  2. Model IDs & endpoints

    • Planned model names (e.g. veo-3-1-generate-*, fast/standard variants)?

    • Any SDK/REST examples we can follow now?

  3. Capabilities

    • Max duration (60s), resolution (1080p), audio support, multi-prompt & transitions (how to specify prompts/segments)?

    • Improvements to identity/clothing consistency and camera motion controls — any new params?

  4. Regions, quotas, rate limits

    • Supported regions at launch, default quotas, typical latency.

  5. Pricing & billing

    • Pricing for Veo 3.1 (per-second or per-request) in Gemini API / Vertex AI.

    • Any differences vs Veo 3 and Veo 3 Fast?

  6. Migration

    • Backward compatibility: can we reuse our Veo 3 requests with minimal changes?

    • Recommended fallback strategy if Veo 3.1 is temporarily unavailable.

Context: We run an API platform that already exposes Veo 3 to customers; having dates, model IDs, and pricing for 3.1 will help us schedule docs, billing, and rollout.

Thanks a lot!

Thank you so much! I also found the AI/ML platform’s API. I have an API key there.
