- First and last frameBoth anchors available, with the last frame requiring a first.
- 4k still availableThe resolution ladder goes to 4k even on the speed tier.

Technique
Prompt tips
- Direct the audio explicitlyAmbience, voice, effects. The speed tier generates sound too, and it responds to being told what kind.
- Use references for identityUp to 3 stills to lock a face, a product or a place. This is the tier that supports them.
- Quote spoken linesQuoted text reads as dialogue, unquoted text reads as description.
- Anchor with a first frameFastest route to the composition you want, on any tier.
- Draft here, finish hereThe gap to the quality tier is smaller than the price gap. Often this tier is the final.
Mechanism
How Veo 3.1 Fast works
Fast runs the same joint picture and audio generation as the quality tier with a smaller compute budget, and it exposes the reference image path that the quality tier does not. In practice that makes it the more flexible model of the two: you trade some fidelity for the ability to lock identity with stills.
