OpenAI Image Gen

Generate a handful of “random but structured” prompts and render them via the OpenAI Images API.

Run

python3 {baseDir}/scripts/gen.py
open ~/Projects/tmp/openai-image-gen-*/index.html  # if ~/Projects/tmp exists; else ./tmp/...

Useful flags:

# 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 robot in a garden" --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)
