Google’s current help table should be treated as the source of truth when a feature in the interface differs.

When to choose Veo 3.1 Lite

Lite currently has the lowest credit cost and is the model Google specifies for extending eligible Veo 3.1 eight-second clips. It is a practical choice for iteration volume and extension workflows.

When to choose Veo 3.1 Fast

Fast uses more credits than Lite but fewer than Quality for non-Ultra users. It supports the common text, frame and ingredient workflows documented for Veo 3.1.

When to choose Veo 3.1 Quality

Quality currently costs 100 credits per generation and supports eight-second output. Use it when the intended workflow justifies the higher allowance cost, not as an automatic default for every exploratory prompt.

When to choose Gemini Omni Flash

Omni Flash currently adds:

  • 10-second generation.

  • Editing of uploaded and generated video.

  • Advanced character, avatar and supported audio references.

  • Custom voice styling from a preset voice.

Some Omni Flash features have country restrictions.

Current image models

Google currently lists Nano Banana Pro, Nano Banana 2 Lite and Nano Banana 2 for image generation and editing inside Flow. The default can depend on the subscription.

A model-selection checklist

Choose in this order:

  1. Required input: text, frames, ingredients or uploaded video.

  2. Required duration.

  3. Whether you need editing or extension.

  4. Country availability.

  5. Credit cost per output and expected retries.

Then confirm the active model and cost in the prompt-box settings before generating.
