# 🎨 T5 Prompt Enhancer V0.3

**The most advanced AI art prompt enhancement model with quad-instruction capability and LoRA control.**

Transform your AI art prompts with precision - simplify complex descriptions, enhance basic ideas, or choose between clean and technical enhancement styles.

## 🚀 Quick Start

```python
from transformers import T5Tokenizer, T5ForConditionalGeneration
import torch

# Load model
model = T5ForConditionalGeneration.from_pretrained("t5-prompt-enhancer-v03")
tokenizer = T5Tokenizer.from_pretrained("t5-prompt-enhancer-v03")

def enhance_prompt(text, style="clean"):
    """Enhanced prompt generation with style control"""
    
    if style == "clean":
        prompt = f"Enhance this prompt (no lora): {text}"
    elif style == "technical":
        prompt = f"Enhance this prompt (with lora): {text}"
    elif style == "simplify":
        prompt = f"Simplify this prompt: {text}"
    else:
        prompt = f"Enhance this prompt: {text}"
    
    inputs = tokenizer(prompt, return_tensors="pt", max_length=256, truncation=True)
    
    with torch.no_grad():
        outputs = model.generate(
            inputs.input_ids,
            max_length=80,
            num_beams=2,
            repetition_penalty=2.0,
            no_repeat_ngram_size=3
        )
    
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Examples
print(enhance_prompt("woman in red dress", "clean"))
# Output: "a beautiful woman in a red dress with flowing hair, elegant pose, soft lighting"

print(enhance_prompt("anime girl", "technical")) 
# Output: "masterpiece, best quality, 1girl, solo, anime style, detailed background"

print(enhance_prompt("A majestic dragon with golden scales soaring through stormy clouds", "simplify"))
# Output: "dragon flying through clouds"
```
