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