Veo 3.1

Veo 3.1 is Google's flagship video model in the Veo 3.1 generation on AI Gateway, the quality ceiling of that generation, with strong motion fidelity, native audio-visual synchronization, and image-to-video support for professional production workflows.

What To Consider When Choosing a Provider

  • Configuration: For professional media and branded content workflows, verify with your provider that the generation quality and output format meet your distribution requirements before scaling production.
  • Zero Data Retention: AI Gateway supports Zero Data Retention for this model via direct gateway requests (BYOK is not included). To configure this, check the documentation.
  • Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.

When to Use Veo 3.1

Best For

  • Final production renders: After prompt direction is validated in the fast tier, Veo 3.1 produces the highest-quality output for final distribution and delivery
  • Professional media and branded content: Advertising, corporate video, documentary segments, and branded social content where frame quality and motion consistency determine whether the output is usable
  • Reference image animation at maximum fidelity: Animating product shots, character art, or architectural renders where the source asset quality must carry through to the output with minimal artifact introduction
  • Synchronized audio for finished content: Scenes requiring precise dialogue timing, music beat alignment, or ambient environment audio in the final cut without separate audio production

Consider Alternatives When

  • Iteration and prompt exploration are ongoing: Veo 3.1 Fast provides comparable generation at reduced cost and latency for the exploration phase
  • You have validated production prompts on Veo 3.0: If your pipeline is tuned to the 3.0 generation and output consistency is a priority, validate 3.1 output before migrating to Veo 3.1
  • Speed or cost is the binding constraint: For high-volume generation where output quality is secondary to throughput, the fast tier is more economical

Conclusion

Veo 3.1 is the final render endpoint for Veo-based video production, the quality ceiling of the Veo 3.1 generation for teams whose workflows require strong motion fidelity and audio-visual synchronization within that lineup.

Frequently Asked Questions

  • What improved in the Veo 3.1 generation over Veo 3.0?

    The 3.1 generation delivers improvements in motion physics accuracy, frame-to-frame object coherence, and audio-visual synchronization precision. In standard-quality mode, these improvements are most pronounced in scenes with complex motion or precise audio timing requirements.

  • How does the fast vs standard quality difference manifest in output?

    Standard Generate applies more generation compute per request, resulting in tighter frame consistency, more accurate motion physics, and better audio-visual alignment on complex scenes. For simple scenes, the difference may be minimal. The gap is most visible on content with fast motion, fine detail, or precise audio timing.

  • What audio generation capabilities does Veo 3.1 include?

    The model generates ambient environment audio, sound effects, and dialogue synchronized to visual events from text prompt descriptions. Audio and video are generated in a single pass without post-production audio assembly.

  • Does Veo 3.1 support image-to-video?

    Yes, provide a reference image alongside a text description to animate it. The model generates video that begins from the reference image with motion described in the prompt.

  • What resolution does Veo 3.1 support?

    Up to 1080p, with duration and aspect ratio options depending on the provider. See the Specs table on this page for the full list.

  • How do I use Veo 3.1 on AI Gateway?

    Use the identifier google/veo-3.1-generate-001 with the generateVideo interface in the AI SDK. AI Gateway handles provider selection and failover automatically.
