Google’s Nano Banana is live for developers through the Gemini API and Google AI Studio in preview. It is an image model officially called Gemini 2.5 Flash Image, and you can try it for free with rate limits. There is also a special 48-hour free unlock running this weekend for builders.
First, what Nano Banana actually is
Nano Banana is a nickname for Gemini 2.5 Flash Image. It generates and edits images with strong character consistency, multi-image fusion and quick local edits. It ships as the gemini-2.5-flash-image-preview model in the API and AI Studio. All outputs have SynthID watermarking.
Good news: @NanoBanana is now available in the Gemini API free tier 🍌 for the weekend (under “gemini-2.5-flash-image-preview”).

About video. Quick clarity so you do not get stuck
Nano Banana itself is for images. For image-to-video in the Gemini stack you use Veo 3 via the Gemini API. Google’s own docs show image to video recipes with Veo. Media reports also confirm the photo to video feature in Gemini is powered by Veo 3. So your workflow is simple. Make images with NanoBanana, then pass them to Veo for video.
