Google made video generation an API call. The ceiling is ten seconds.
Google shipped Nano Banana 2 Lite and Gemini Omni Flash on June 30. The first generates images in about four seconds at $0.034 per thousand; the second animates them conversationally at $0.10 per second of video output. Together they're the cheapest complete image-to-video pipeline on the market right now — as long as ten seconds is enough.
