Nano Banana 2.1 於 AI Gateway 上可使用

Nano Banana 2.1 from Google is now available on AI Gateway. It improves image generation and editing over earlier Nano Banana models.

This release targets product recontextualization, mask- and ink-based editing, and factuality. Product recontextualization places an existing product in a new scene. Mask- and ink-based edits change only the region marked by a mask or by strokes drawn on the image. Factuality is how accurately images depict real-world subjects.

The model renders photorealistic skin tones, intricate materials, sharp lighting, and coherent backgrounds at the latency and cost of a Flash-tier model.

Call it through the AI SDK or the OpenAI-compatible Chat Completions API, or the AI CLI. AI CLI is an open-source command-line tool from Vercel Labs for generating text, images, video, and audio from your terminal. It runs on AI Gateway, so any Gateway model ID works with -m.

Use google/gemini-nano-banana-2.1 as the model name. Generated images are returned in result.files:

Try Nano Banana 2.1 in imagen.sh, or the model playground.
