Google Flow is Google's AI filmmaking tool, built on the Veo model family (currently Veo 3.1), that generates video from text prompts or images with native audio — sound effects, ambience, and dialogue generated alongside the picture rather than added afterward. Access runs through a Google AI subscription: a free Gemini tier covers basic use, while Google AI Pro ($19.99/month) and Google AI Ultra unlock higher generation limits and resolution.
Who builds it
Flow is developed by Google as part of its Gemini/Labs product family and sits alongside Google's broader Veo video-generation efforts. Rather than selling Flow as a standalone product, Google bundles access to it inside its Gemini subscription tiers, so pricing and limits track the wider Google AI plan you're on rather than a Flow-specific price sheet.
Core features
- Text-to-video — generate a video scene directly from a written prompt.
- Image-to-video — animate up to 5 uploaded photos into video.
- Native audio generation — city sounds, ambient noise, and even dialogue are generated together with the visuals, not layered on afterward.
- Built on Veo 3.1 — Google's current video-generation model family powering Flow's output.
- SynthID watermarking — every video generated in the Gemini app is marked with SynthID, Google's invisible watermark for identifying AI-generated content.
- Tiered generation limits — clip length and resolution scale with your Google AI subscription tier rather than a Flow-specific plan.
Pricing
Flow doesn't have independent pricing; it's accessed through Google's Gemini/Google AI subscriptions. A free tier is available with a Google account at $0/month. Google AI Pro costs $19.99/month and raises generation limits; Google AI Ultra unlocks Flow's highest limits, including 1080p video generation. Reported clip length for Gemini Omni Flash-generated videos is around 10 seconds per generation, though this reflects model capability rather than a stated hard maximum. Flow's pages don't spell out separate commercial-use terms or confirm public API access, so treat those as unconfirmed until you check Google's current terms directly.
Who it's for
Flow suits creators and filmmakers experimenting with AI-generated scenes who want synchronized audio generated alongside the video rather than added in post — a distinguishing feature versus most silent-by-default text-to-video tools. Because access and limits are tied to a Google AI subscription rather than a Flow-only price, it's a natural fit for anyone already paying for Gemini/Google AI who wants to add video generation without a separate subscription, while heavier professional use may hit Flow's clip-length and resolution ceilings faster than dedicated generative-video platforms.
