Flow provides a range of features powered by various Veo models, in addition to Imagen 4 and Gemini. Different models support different features.
- Veo 2 is our default model and supports the full Flow experience. We recommend it for most uses.
- Veo 3.1 is our newest model and will offer the best quality and experimental audio.
Tip: Before generating, in the prompt box settings, check the active model and the latest credit costs.

Audio Generation
Important: This is an experimental feature only available on the Veo 3.1 model.
You can now add sound effects and background noise, as well as speech in some cases.
- Add your guidance to the prompt itself. For example:
the sound of an ice cream truck can be heard in the backgroundthe captain turns towards the ocean and says ”we set sail at daybreak!”
- Sometimes Veo can produce low-quality audio, in which case your video will not be generated. Instead, your credits will be refunded. If you get this error, you can try again or try another prompt.
- Speech generation performs better with longer text transcripts in your prompt.
- We’re working on improving the following known issues:
- Speech is currently muted on generations depicting minors.
- Generated speech may incorrectly trigger on-screen subtitles.
Send us your feedback on this feature so we can iterate on it.
