Which one to pick

  • Veo 3.1 Lite

    High-volume text-to-video where you are generating many candidates and throwing most away. The cheapest tier by a wide margin, but it takes a prompt only — no reference images.

  • Veo 3.1 Fast

    The default choice. Adds image-to-video on top of text-to-video, with both first-frame and reference-image modes, at roughly twice the Lite price.

  • Veo 3.1 Quality

    Final renders where the clip ships. Same inputs and settings as Fast, priced for output you are not going to regenerate.

Strengths

  • Identical parameter surface across all three tiers — switching tier is a one-word change, not a rewrite.
  • 4K output available on every tier, not reserved for the expensive one.
  • Every tier is served by the same provider routing, so a tier change needs no new credentials or endpoint.

Limitations

  • Clip length is fixed — there is no duration parameter, so you cannot ask for a shorter or longer take.
  • Only 16:9 and 9:16 aspect ratios — no square (1:1) and no 4:3 or 3:4 framing.
  • Lite cannot accept a reference image, so any image-to-video work starts at the Fast tier.
