Veo 3.1 vs Veo 3.1 Fast

Veo 3.1 and Veo 3.1 Fast differ on 3 specifications — from what each one costs to which inputs it accepts. Every value below is read from the live model catalog, so it stays current as new versions ship.

Which should you use?

Same family, same 4K ceiling and same 4/6/8 second options — Veo 3.1 Fast is the cheaper tier at 15 credits against 25, so run Fast while you iterate and the full model for the take that ships.

The two share a specification almost exactly: 720p, 1080p or 4K, at a fixed 4, 6 or 8 seconds, with synced audio available on both. The catalog difference is price — Veo 3.1 Fast starts at 15 credits and tops out at 50, against 25 to 72 for the full model.

That makes the split a familiar one. A fast tier exists so that the expensive model is not what you burn credits on while deciding framing, pacing and prompt wording. Nothing about the Fast tier is worse on paper; it is the same delivery ceiling and the same duration options.

The practical workflow is to settle everything on Fast, then re-run the final prompt on Veo 3.1 at the resolution you are delivering. If the Fast output is already good enough for the context, there is no rule that says you have to.

Pick Veo 3.1 when

  • The shot is being delivered and you want the full model's output quality.
  • It is a hero shot where the difference is worth 10 extra credits.

Pick Veo 3.1 Fast when

  • You are iterating — 15 credits against 25 means roughly two-thirds more attempts for the same spend.
  • The clip is a background plate, a cutaway, or anything the viewer sees briefly.
  • You are generating variations to choose from rather than finishing a shot.
