Nano Banana Pro with Fallback

Use the bundled script to generate or edit images. Automatically falls back through multiple Gemini models if one fails.

⚠️ IMPORTANT: MUST use uv run or the generate wrapper. Do NOT use python3 directly — dependencies won't be available.

{baseDir}/scripts/generate --prompt "your image description" --filename "output.png" --resolution 1K

Generate (option B: uv run)

uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output.png" --resolution 1K

Edit (single image)

uv run {baseDir}/scripts/generate_image.py --prompt "edit instructions" --filename "output.png" -i "/path/in.png" --resolution 2K

Multi-image composition (up to 14 images)
