▶README

Nano Banana

Image generation and editing with Google's Gemini image models — codenamed "Nano Banana."

Tools

generate_image (Standard)

Gemini 2.5 Flash Image. Fast and affordable. Good for everyday image generation, asset variations, and prompt iteration.

{
  "prompt": "Isometric pixel-art bakery storefront, soft morning light",
  "aspect_ratio": "1:1"
}

generate_image_pro

Gemini 3 Pro Image. Higher fidelity, supports up to 4K output, better at fine detail and typography. Use when quality matters more than throughput.

{
  "prompt": "Editorial-style product photo of a ceramic teapot on dark walnut",
  "aspect_ratio": "16:9",
  "resolution": "2K"
}

Both tools also accept input images for editing / composition — pass reference images alongside the prompt and the model will use them as a visual anchor.

Useful options

  • aspect_ratio — 1:1, 4:3, 3:4, 16:9, 9:16
  • resolution (pro only) — 1K, 2K, 4K
  • images — reference images for edit / composition mode

Pricing

Variable, billed from upstream Google AI usage on completion. Roughly:

  • Standard 1024×1024: ~5 credits (≈ $0.005)
  • Pro 2K: ~30 credits (≈ $0.03)
  • Pro 4K: ~50 credits (≈ $0.05)

Charged only on success.

Auth

A Google AI Studio API key on the publisher's Faro connection — no user-side configuration required.
