Our review
Generates and edits images using NVIDIA's FLUX models through a Python CLI.
Strengths
- Supports multiple models for different speed/quality tradeoffs.
- Includes aspect ratio presets and custom size parameters.
- Allows reproducible generation with seed and step controls.
- Can edit existing images with simple text instructions.
Limitations
- Requires access to the NVIDIA API; the embedded API key may need to be overridden.
- Limited to predefined aspect ratios and resolutions unless custom width/height are specified.
- No mention of batch generation or advanced post-processing.
When you need to quickly generate or edit images from text prompts without setting up a complex image generation pipeline.
When you need fine-grained control over model weights or offline generation without an API.
Security analysis
SafeThe skill uses a Python script for image generation via NVIDIA API, with no destructive commands, token exfiltration, or obfuscation. The API key is embedded but can be overridden, and no suspicious external calls are present.

Examples
Basic Generation
python scripts/generate.py "A mountain landscape at sunset"
Wide Format (16:9)
python scripts/generate.py "A panoramic beach view" -ar 16:9
Portrait Mode (9:16)
python scripts/generate.py "A professional headshot" -ar 9:16
Custom Size
python scripts/generate.py "A banner image" --width 1344 --height 768
Fast Generation
python scripts/generate.py "Quick sketch of a robot" -m schnell
Edit an Image
python scripts/generate.py "Make the background a sunset" -i input.jpg -o output.png
Reproducible Results
python scripts/generate.py "A robot" --seed 12345
Output
The script outputs MEDIA:/path/to/image.png which can be sent directly to chat.
API Key
The API key is embedded in the script. To use a different key, set the NVIDIA_API_KEY environment variable.
