| # 🎨 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" |
| ``` |
|

| ### Prompt Engineering Workflow |
| ```python |
| # Iterative refinement |
| original = "A complex, detailed description of a beautiful woman..." |
