OpenAI Image Gen

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

Run

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 (

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
