🔎

Use this repo as a GPT Image 2 prompt gallery, image prompt library, example of generation showcase, Codex / Claude Code agent skill, and gpt-image-2 CLI. It includes reusable AI image prompts for research paper figures, posters, UI mockups, game HUDs, anime / manga, photography, typography, maps, tattoo design, and reference-image editing workflows.

This project is not trying to collect every prompt on the internet. We keep a selected set of examples that show what GPT Image 2 can do and how to use it well. Thanks for all the love this little gallery has received 🫶.

[!CAUTION] For research figures, treat generated images as references, workflow sketches, or reproducible style targets. We do not recommend dropping GPT Image 2 outputs directly into a paper as-is; for academic communication, that can be misleading and is generally bad practice.

📥

Before installing, check whether the skill or CLI is already available. Do not reinstall blindly, overwrite an existing skill folder, or create/replace API-key files. Use your runtime’s own skill list/status command when available; global/shared installs should be an explicit user choice, not an automatic setup step.

command -v gpt-image || true
command -v uv >/dev/null && uv tool list | grep -E '^gpt-image-cli([[:space:]]|$)' || true
test -n "${OPENAI_API_KEY:-}" && echo "OPENAI_API_KEY is already set (value hidden)"

Reads OPENAI_API_KEY from process env, then .env, then ~/.env without overriding an already-set env var.

Agent + API-key note. Codex also has its own built-in image-generation skill, but that path is black-box and cannot be edited here; Codex users can switch to it if they prefer. Thanks to the related issue discussion for the simple safety tip: if you do not want an agent to accidentally use your OpenAI API key, run unset OPENAI_API_KEY before invoking the local CLI/skill.

⚡ Quick Usage & Prompting Fundamentals

Budget / quality guide

There is no separate budget flag here — use --quality as the budget knob.

• low = cheap draft / collect / many variants
• medium = normal exploration / style probing
• high = final posters, Chinese text, diagrams, paper figures, banners

If you are generating dozens of candidates, start at low and only rerun finalists at high.

From gallery prompt → CLI / SDK

Every entry below ships just the prompt plus a metadata line ("size" · "quality" · source). Assemble the CLI / SDK call the same way every time — worked once here so per-entry code blocks can stay out of your way. Example for a "portrait" · "high" entry:

# CLI
gpt-image -p "" --size portrait --quality high -f out.png

# OpenAI SDK — `size` is the literal pixels; the CLI shortcut maps to `1024x1536` for portrait
from openai import OpenAI
client = OpenAI()
result = client.images.generate(
    model="gpt-image-2",
    prompt="",
    size="1024x1536",
    quality="high",
)

For reference-based edits, add -i ref.png (repeatable) and optionally -m mask.png on the CLI, or call client.images.edit(...) with image=[open(p, "rb") for p in refs]. Everything else stays identical to the generate path.

Exit codes: 0 success · 1 API/refusal error (full response body echoed to stderr) · 2 bad args or missing OPENAI_API_KEY.
