## Text Rendering Tips

For best text results with the Pro model:

1. **Use quotes** around exact text: `"Title: \"Hello World!\""`
2. **Specify font details**: color, style, size, position
3. **Disable prompt_extend**: Set `prompt_extend: false` for precise control
4. **Use negative prompts**: `"blurry text, distorted text, low quality"`

**Example prompt structure:**
```
Poster with the title "GRAND OPENING" in large red serif font at the top center.
Below, the date "March 15, 2024" in smaller black text.
Background: elegant gold and white gradient.
Style: professional, clean, modern.
```

## Recommended Negative Prompt

```json
{
  "negative_prompt": "low resolution, low quality, deformed limbs, deformed fingers, oversaturated, waxy, no facial details, overly smooth, AI-like, chaotic composition, blurry text, distorted text"
}
```

## Sample Workflow

```bash
# 1. Generate sample input to see all options
infsh app sample alibaba/qwen-image-2-pro --save input.json

# 2. Edit the prompt
# 3. Run
infsh app run alibaba/qwen-image-2-pro --input input.json
```

## Python SDK

```python
from inferencesh import inference

client = inference()

# Text-heavy poster
