# Image Generation
Generate images from text prompts. Multiple provider options.
## Option A: OpenAI DALL-E 3 (Best quality)
Requires `OPENAI_API_KEY`.
```python
from openai import OpenAI
client = OpenAI()
response = client.images.generate(
model="dall-e-3",
prompt="A serene mountain lake at sunset, photorealistic",
size="1024x1024",
quality="standard", # or "hd"
n=1,
)
image_url = response.data[0].url
```
Sizes: `1024x1024`, `1792x1024`, `1024x1792`
## Option B: Pollinations.ai (Free, no key)
```bash
# Simple GET request - returns PNG
curl "https://image.pollinations.ai/prompt/A%20cat%20wearing%20sunglasses" -o output.png
# With parameters
curl "https://image.pollinations.ai/prompt/YOUR_PROMPT?width=1024&height=1024&seed=42" -o output.png
```
## Option C: Stability AI
Requires `STABILITY_API_KEY`.
```bash
curl -X POST "https://api.stability.ai/v2beta/stable-image/generate/sd3" \
-H "authorization: Bearer $STABILITY_API_KEY" \
-H "accept: image/*" \
-F "prompt=lighthouse on a cliff" \
-F "output_format=png" \
-o output.png
```
## Script
```bash
python3 scripts/generate_image.py "A cat in space" --provider dalle --output /tmp/gen.png
python3 scripts/generate_image.py "Logo design" --provider dalle --size 1024x1024
python3 scripts/generate_image.py "Mountains" --provider stability --output landscape.png
```
Requires API key environment variable:
- DALL-E: `export OPENAI_API_KEY=sk-xxx`
- Stability AI: `export STABILITY_API_KEY=sk-xxx`
## Prompt Tips
- Be specific: "a red fox sitting in snow, photorealistic, 4K" > "fox"
- Style keywords: photorealistic, watercolor, oil painting, pixel art, anime
- Negative: avoid ambiguous words, be descriptive
