# AI Image Generation

Generate images from text prompts using OpenAI GPT Image (gpt-image-2 / gpt-image-1 / variants) or Stability AI (SD 3.5 Large).

## Tool Location

- Script: `~/.agents/tools/generate-image.py`
- Env file: `~/.agents/tools/.env` (contains `OPENAI_API_KEY` and `STABILITY_API_KEY`)

## Available OpenAI image models (verified live via `/v1/models` 2026-05-15)

| Model ID | Notes |
|---|---|
| `gpt-image-2` | **Flagship.** Released 2026-04-21. Best prompt adherence, best photorealism. Default when image quality matters. |
| `gpt-image-2-2026-04-21` | Pinned dated variant of gpt-image-2 |
| `gpt-image-1.5` | Intermediate release between 1 and 2 |
| `gpt-image-1-mini` | Smaller/cheaper gpt-image-1 variant — use for batch/draft generation where cost matters |
| `gpt-image-1` | Original gpt-image. Still works; superseded by gpt-image-2. |
| `chatgpt-image-latest` | Always-current alias of the model ChatGPT.com uses (currently gpt-image-2-class). Use when you want "whatever ChatGPT uses today" |
| `dall-e-3` | Legacy fallback. Different quality semantics (standard/hd, not low/medium/high). |

Pass any of these to `--model`. The script branches on `gpt-image*` for the quality/format handling, so all gpt-image-* variants work out of the box.

**Default in the script is now `gpt-image-2`** (the flagship) — pass `--model gpt-image-1-mini` for cheap batch/draft work.

## Quick Usage

### Generate with OpenAI gpt-image-2 (flagship)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "a sunset over mountains, oil painting style" \
  --output ./sunset.png \
  --model gpt-image-2 \
  --quality high
```

### Generate with default (gpt-image-2)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "a sunset over mountains, oil painting style" \
  --output ./sunset.png
```

### High quality

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "modern logo design for a tech company" \
  --output ./logo.png \
  --size 1024x1024 \
  --quality high
```

### Wide format (good for blog covers, banners)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "abstract digital art with blue tones" \
  --output ./banner.png \
  --size 1536x1024
```

### Tall format (good for mobile, stories)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "portrait of a futuristic city" \
  --output ./city.png \
  --size 1024x1536
```

### Transparent background (icons, logos)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "a minimalist cat icon, flat design" \
  --output ./icon.png \
  --background transparent
```

### Generate with Stability AI (SD 3.5 Large)

```bash
python ~/.agents/tools/generate-image.py \
  --prompt "watercolor painting of a garden" \
  --output ./garden.png \
  --provider stability
```
