Gemini Image Generator

This skill generates images using Google's Gemini model. It is configured to be cost-efficient by defaulting to standard resolution models.

Usage

python3 {script_path} "Prompt" [--model model_name] [--output filename.png] [--no-open]

IMPORTANT: Model Selection Policy (Quota Saving)

Always default to standard resolution models. Do NOT use 4K models unless the user explicitly mentions "4K", "Ultra HD", or "High Definition".

Available Models

| Model Name | Aspect Ratio | Resolution | Cost Category | | :--- | :--- | :--- | :--- | | gemini-3-pro-image (Default) | 1:1 | Standard | Low (Recommended) | | gemini-3-pro-image-16x9 | 16:9 | Standard | Low (Recommended) | | gemini-3-pro-image-9x16 | 9:16 | Standard | Low (Recommended) | | gemini-3-pro-image-4k | 1:1 | 4K | High | | gemini-3-pro-image-4k-16x9 | 16:9 | 4K | High | | gemini-3-pro-image-4k-9x16 | 9:16 | 4K | High |

Decision Logic for Alma

1. Default: Use gemini-3-pro-image.
2. Aspect Ratio:
   • If "landscape/widescreen/16:9", use gemini-3-pro-image-16x9.
   • If "portrait/mobile/9:16", use gemini-3-pro-image-9x16.
3. 4K (Only if explicitly requested):
   • Only upgrade to a -4k model if the user explicitly says "4K" or equivalent high-res keywords.

Note on Display

Alma's chat UI does not render local images. The skill uses open to show the image in the system viewer.
