What is openai-image-gen?

A command-line script for creating batches of images through the OpenAI Images API, with an HTML gallery for viewing the results. It supports several image models and output settings.

Generating visual concepts, illustrations, photos, and other image variations from prompts, including batches for comparison.

It removes repetitive manual image generation and puts multiple results in one browsable gallery. It can also create images with transparent backgrounds or different sizes and formats.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00025	$0.00907
Opus 5	$0.00013	$0.00453
Sonnet 5	$0.00005	$0.00181
Haiku 4.5	$0.00003	$0.00091

Security

Grade A, and why

openai-image-gen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/gen.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 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)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

An honesty gate that makes an AI back up its claims with real evidence instead of presenting guesses as fact.

comment-reaper

Finds and removes unnecessary code comments - the ones that restate the code, cite an issue number, narrate refactor history, or wrap a one-line function in six lines of JSDoc. Sorts every find into auto-fix, propose, or never-touch, so the WHY comments survive the sweep. Trigger on: "comment reaper", "reap comments"…
