# OpenAI Image Gen
Generate a handful of “random but structured” prompts and render them via the OpenAI Images API.
## Run
Note: Image generation can take longer than common exec timeouts (for example 30 seconds).
When invoking this skill via OpenClaw’s exec tool, set a higher timeout to avoid premature termination/retries (e.g., exec timeout=300).
```bash
python3 {baseDir}/scripts/gen.py
open ~/Projects/tmp/openai-image-gen-*/index.html # if ~/Projects/tmp exists; else ./tmp/...
```
Useful flags:
```bash
# GPT image models with various options
python3 {baseDir}/scripts/gen.py --count 16 --model gpt-image-1
python3 {baseDir}/scripts/gen.py --prompt "ultra-detailed studio photo of a lobster astronaut" --count 4
python3 {baseDir}/scripts/gen.py --size 1536x1024 --quality high --out-dir ./out/images
python3 {baseDir}/scripts/gen.py --model gpt-image-1.5 --background transparent --output-format webp
# DALL-E 3 (note: count is automatically limited to 1)
python3 {baseDir}/scripts/gen.py --model dall-e-3 --quality hd --size 1792x1024 --style vivid
python3 {baseDir}/scripts/gen.py --model dall-e-3 --style natural --prompt "serene mountain landscape"
# DALL-E 2
python3 {baseDir}/scripts/gen.py --model dall-e-2 --size 512x512 --count 4
```
## Model-Specific Parameters
Different models support different parameter values. The script automatically selects appropriate defaults based on the model.
### Size
- **GPT image models** (`gpt-image-1`, `gpt-image-1-mini`, `gpt-image-1.5`): `1024x1024`, `1536x1024` (landscape), `1024x1536` (portrait), or `auto`
- Default: `1024x1024`
- **dall-e-3**: `1024x1024`, `1792x1024`, or `1024x1792`
- Default: `1024x1024`
- **dall-e-2**: `256x256`, `512x512`, or `1024x1024`
- Default: `1024x1024`
### Quality
- **GPT image models**: `auto`, `high`, `medium`, or `low`
- Default: `high`
- **dall-e-3**: `hd` or `standard`
- Default: `standard`
- **dall-e-2**: `standard` only
- Default: `standard`
### Other Notable Differences
- **dall-e-3** only supports generating 1 image at a time (`n=1`). The script automatically limits count to 1 when using this model.
- **GPT image models** support additional parameters:
- `--background`: `transparent`, `opaque`, or `auto` (default)
- `--output-format`: `png` (default), `jpeg`, or `webp`
- Note: `stream` and `moderation` are available via API but not yet implemented in this script
- **dall-e-3** has a `--style` parameter: `vivid` (hyper-real, dramatic) or `natural` (more natural looking)
## Output
- `*.png`, `*.jpeg`, or `*.webp` images (output format depends on model + `--output-format`)
- `prompts.json` (prompt → file mapping)
- `index.html` (thumbnail gallery)Related Skills
