Draft:Nano Banana (Chatbot)

Nano Banana Image Generation is an unofficial community term used for third‑party websites, libraries and interfaces that expose image generation via Google’s multimodal Gemini API and the Imagen family of models on Vertex AI. As of 31 August 2025, Google has not introduced or documented any product or model officially titled “Nano Banana”; official Google documentation describes image generation under the Imagen 3 series on Vertex AI and, in the Gemini API, multimodal responses that can include images alongside text. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/image/overview?utm_source=openai))

Background

[edit]

Google Cloud provides image generation as part of Vertex AI through the Imagen models. In December 2024, Google announced general availability of Imagen 3 image‑generation models, expanding quality and access for customers using Vertex AI. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/release-notes?utm_source=openai)) In 2025, Google deprecated Imagen versions 1 and 2 (effective 24 June 2025) with removal scheduled for 24 September 2025, and published migration guidance to Imagen 3. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/deprecations?utm_source=openai))

Separately, the Gemini API supports multimodal generation. When using Gemini to produce images, configuration must request both text and image modalities; image‑only responses are not supported by these models. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/multimodal/image-generation?utm_source=openai))

Description

[edit]

Under the “Nano Banana” label, community projects typically combine:

  • Gemini for iterative prompt development, reasoning, or conversational editing; and
  • Imagen 3 for final, higher‑fidelity renders delivered through Vertex AI.

Google’s Imagen 3 documentation (for example, model version imagen‑3.0‑generate‑002) details supported resolutions, aspect ratios, language support, request limits and safety controls. ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/models/imagen/3-0-generate-002?utm_source=openai))

Features and responsible AI

[edit]

According to Google Cloud, Imagen‑generated assets carry an invisible digital watermark (SynthID) by default, and developers can programmatically verify the watermark. Vertex AI documentation and blog posts describe watermarking, verification workflow, and configurable safety filters (for example, person‑generation controls and safety thresholds). ([cloud.google.com](https://cloud.google.com/vertex-ai/generative-ai/docs/image/generate-images?utm_source=openai))

Adoption and ecosystem

[edit]

“Nano Banana” is a community nickname rather than an official Google brand. Third‑party wrappers and sites may offer simple interfaces or libraries built on top of Google Cloud’s APIs. One example is the community site nano-banana-image-ai.com. As with any third‑party wrapper, developers typically connect their own Vertex AI or Gemini credentials server‑side and should review data‑handling and billing practices before use.
