Generate images with GPT Image 2 (ChatGPT Images 2.0) inside Claude Code,
using your existing ChatGPT Plus or Pro subscription β no separate OpenAI
access, no per-image billing. Supports text-to-image, image-to-image
editing, style transfer, and multi-reference composition via the local
Codex CLI. Triggers on "gpt image 2", "gpt-image-2", "ChatGPT Images 2.0",
"image 2", or any explicit ask to generate or edit an image through the
user's ChatGPT plan.

# πͺ GPT Image 2 β Image Generation via Your ChatGPT Subscription
[agentspace.so](https://agentspace.so/?utm_source=clawhub&utm_medium=skill&utm_campaign=gpt-image-2-chatgpt) Β· [GitHub](https://github.com/agentspace-so/skills/tree/main/gpt-image-2)
Generate images with **GPT Image 2** (ChatGPT Images 2.0) inside your agent, using your existing ChatGPT Plus or Pro subscription β **no separate OpenAI access, no Fal or Replicate tokens, no per-image billing.**
Text-to-image, image-to-image editing, style transfer, and multi-reference composition. Runs entirely through the local `codex` CLI you're already logged into.
> **Heads up β this skill requires a ChatGPT Plus or Pro subscription _plus_ the Codex CLI installed locally.** If you have neither, you can use GPT Image 2 in the browser via RunComfy instead β hosted, no ChatGPT subscription or local install needed (RunComfy account required):

*Example output: a plain flat-color icon repainted via `--ref` in ukiyo-e style β composition preserved, rendering swapped, period-appropriate red seal added by the model unprompted.*
## When to trigger
Trigger when the user explicitly asks for GPT Image 2 via their ChatGPT subscription, for example:
- "use GPT Image 2" / "use gpt-image-2" / "use ChatGPT Images 2.0"
- "use Image 2" / "image 2 this"
- attached a reference image and asked to remix / edit / restyle it
Do **not** auto-trigger for a plain "generate an image" request if the user didn't specify this route. If they did specify it, do not silently fall back to HTML mockups, screenshots, or a different image model.
## How to invoke
A single bash script handles everything: runs `codex exec` with the right flags, then decodes the generated image from the persisted session rollout.
**Text-to-image:**
```bash
bash scripts/gen.sh \
--prompt "<user's raw prompt>" \
--out <absolute/path/to/output.png>
```
**Image-to-image** (reference flag is repeatable for multi-reference composition):
```bash
bash scripts/gen.sh \
--prompt "<user's raw prompt, e.g. 'repaint in watercolor'>" \
--ref /absolute/path/to/reference.png \
--out <absolute/path/to/output.png>
```
Optional: `--timeout-sec 300` (default 300).
## Default behavior
- **Pass the user's prompt through raw.** Do not translate, polish, or add style modifiers unless the user asked for it.
- **Choose the output path.** Default to `./image-<YYYYMMDD-HHMMSS>.png` in the current working directory if the user didn't specify.
- **Deliver the image.** After the script succeeds, display / attach the output file. Do not stop at "done, see path X".
- **Text-heavy layouts are fine.** Image 2 handles infographics and timeline prompts well. Do not preemptively warn just because a prompt has a lot of text.
## Hard constraints
- Do not switch routes without permission. If the user said "use GPT Image 2", do not substitute DALLΒ·E, Midjourney, an HTML mockup, or a manual screenshot workflow.
- Do not rewrite the prompt unless asked.
- Do not imply this skill works without a local `codex` login and a valid ChatGPT subscription with image-generation entitlement.
## Prerequisites
1. `codex` CLI installed β `brew install codex` or see [openai/codex](https://github.com/openai/codex).
2. Logged in with a ChatGPT plan that includes Image 2 β `codex login`.
3. `python3` on PATH (ships with macOS; `apt install python3` on Linux).
This skill does **not** grant image-generation capability on its own. It exposes the capability the user already has through their ChatGPT subscription.
## Exit codes
| code | meaning |
|------|---------|
| 0 | success β output path printed on stdout |
| 2 | bad args |
| 3 | `codex` or `python3` CLI missing |
| 4 | `--ref` file does not exist |
| 5 | `codex exec` failed (auth? network? model?) |
| 6 | no new session file detected |
| 7 | imagegen did not produce an image payload (feature not enabled, quota, or capability refused) |
On failure, name the layer in one sentence instead of dumping the full stderr at the user.
## How it works
The `codex` CLI reuses the logged-in ChatGPT session and exposes an `imagegen` tool (gated behind the `image_generation` feature flag). The script:
1. snapshots `~/.codex/sessions/` before the run
2. runs `codex exec --enable image_generation --sandbox read-only ...` (with `-i <file>` for each reference image)
3. diffs the sessions directory, then invokes `scripts/extract_image.py` to scan every new rollout JSONL for a base64 image payload (PNG / JPEG / WebP magic-header match)
4. decodes the largest matching blob and writes it to `--out`
Two non-obvious flags other wrappers get wrong on codex-cli 0.111.0+:
- `--enable image_generation` is **required**; the feature is still under-development and off by default.
- `--ephemeral` **must not** be used β ephemeral sessions aren't persisted, so the image payload has nowhere to live.
## Data handling
The script is narrowly scoped on purpose:
- It reads **only** session rollout files created by its own `codex exec` invocation. The sessions directory is snapshotted before the call and diffed after, so any prior `~/.codex/sessions/*` files (which may contain unrelated Codex conversations) are never touched, read, or transmitted.
- It writes only two kinds of file: the output PNG at the caller's `--out` path, and short-lived `mktemp` logs that are auto-deleted on exit via a trap.
- No environment variables are read. No credentials are requested. No other paths under `~/.codex/` are accessed.
- No network calls leave this skill. The only outbound traffic is the one made by the `codex` CLI itself (to OpenAI, using the user's existing ChatGPT login) β this skill does not add endpoints, telemetry, or callbacks.
## What this skill is not
Not a direct OpenAI API client. Not a capability grant β it depends on the user's working Codex CLI login. Not a multi-tenant service (one call per invocation; concurrent calls are serialized by the filesystem-snapshot diff).
