Gemini Image (Nano Banana) in brief
Gemini Image is Google’s hosted image generation and editing capability, available in the Gemini app, Google AI Studio, the Gemini API, and Vertex AI. Google introduced the original Nano Banana in 2025 as Gemini 2.5 Flash Image, then introduced Nano Banana Pro on November 20, 2025. The current Gemini image page identifies Nano Banana 2.1 as the advanced consumer model, while Google’s developer documentation lists Nano Banana 2.1, Nano Banana 2 Lite, Nano Banana 2, Nano Banana Pro, and the original Nano Banana. Google does not publish a separate employee count or funding figure for this product. It is a managed service, not an isolated open model or self-hosted package.
The workflow is conversational. In Gemini, select Create images, write a prompt, or upload an image, then request changes in follow-up turns. Google highlights character consistency, reference-style transfer, photo combination, localized edits, camera and lighting changes, aspect-ratio changes, and text in multiple languages. The API accepts text and image content through the Interactions API, allowing applications to generate, edit, and iterate on images. Nano Banana Pro supports up to 14 input images and can preserve the resemblance of up to five people, according to Google’s launch material. Google embeds SynthID in generated images, and free and Google AI Pro outputs also receive a visible AI watermark.
Nano Banana has fewer production-management features than Adobe Firefly, Midjourney, or Freepik AI. Google exposes changing consumer quotas rather than a published unlimited-generation plan, model names differ between the Gemini app and developer products, and the API requires developers to handle their own application workflow. Adobe Firefly offers a broader Adobe-centered production workflow, Midjourney focuses on image creation through its own subscription service, and Freepik combines generation with stock assets and other media tools. Choose Nano Banana for conversational editing, reference composition, readable image text, Google Search grounding, or Google API access. Choose a competitor when asset libraries, team production controls, or a dedicated creative workspace matter more.
