Nano Banana Pro

# Nano Banana Pro Generate and edit images using Google's Gemini 3 Pro Image API, supporting text-to-image and image-to-image workflows at 1K, 2K, or 4K resolution. Nano Banana Pro lets you generate new images from text prompts or edit existing images using Google's Gemini 3 Pro Image API. It supports multiple resolution outputs (1K, 2K, 4K) and follows a draft-to-final iterative workflow for efficient prompt refinement. ## How It Works The skill provides a Python script that interfaces with the Gemini 3 Pro Image API. For image generation, you supply a text prompt and the script produces a PNG file. For image editing, you provide an input image along with editing instructions. The script is invoked via uv run and saves output images to your current working directory with timestamped filenames.The recommended workflow is: start with 1K drafts for rapid iteration, refine your prompt, then produce the final image at 4K resolution once you're satisfied. ## Key Features Text-to-Image Generation — Create images from descriptive text prompts using Gemini 3 ProImage-to-Image Editing — Modify existing images with natural language instructions (add/remove elements, change style, adjust colors)Multi-Resolution Output — Choose from 1K (~1024px), 2K (~2048px), or 4K (~4096px) resolutionDraft-to-Final Workflow — Iterate quickly at low resolution, then produce high-res finals when the prompt is lockedTimestamped Filenames — Automatic filename generation with yyyy-mm-dd-hh-mm-ss-name.png patternPrompt Templates — Built-in templates for both generation and precise editing tasks ## Requirements LLM API Key — A Google Gemini API key (GEMINI_API_KEY) for accessing the Gemini 3 Pro Image APIPython Runtime — Requires uv to be installed for running the Python generation script ## Use Cases Concept Art & Mockups — Quickly generate visual concepts for design projectsPhoto Editing — Modify existing images: remove objects, change backgrounds, apply style transfersContent Creation — Generate illustrations and graphics for blogs, presentations, or social mediaIterative Design — Rapidly refine image prompts at low resolution before committing to high-res output ## Installation Install via: `npx clawhub@latest install nano-banana-pro`
