T5-Small Art Generation Bidirectional Prompt Converter

A fine-tuned T5-small model for bidirectional prompt transformation in AI art generation.

Model Description

This model can convert between simple descriptions and elaborate art generation prompts in both directions:

• Simple → Elaborate: Transform basic descriptions into rich, detailed art prompts
• Elaborate → Simple: Extract core concepts from complex prompts

Training Data

Trained on 53K+ high-quality prompt pairs with saturation control to reduce bias:

• Simple descriptions from BLIP2 image analysis
• Elaborate prompts from curated art generation datasets
• Bias reduction: Capped "beautiful woman" and similar oversaturated content
• Balanced bidirectional training (50/50 split)

Usage

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("mitchins/t5-small-artgen-bidirectional")
model = T5ForConditionalGeneration.from_pretrained("mitchins/t5-small-artgen-bidirectional")

# Simple to elaborate
input_text = "Generate a detailed artistic prompt for: a cat sitting on a table"
inputs = tokenizer.encode(input_text, return_tensors="pt")
outputs = model.generate(inputs, max_length=200, num_beams=3, temperature=0.8, do_sample=True)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(result)

# Elaborate to simple  
input_text = "Simplify this prompt: A majestic golden dragon soaring through storm clouds above a medieval castle, with lightning illuminating its scales in photorealistic detail"
inputs = tokenizer.encode(input_text, return_tensors="pt")
outputs = model.generate(inputs, max_length=200, num_beams=3, temperature=0.8, do_sample=True)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(result)

Examples

Simple → Elaborate:

• Input: "Generate a detailed artistic prompt for: a robot in a garden"
• Output: "A colossal, bioluminescent robot stands in a lush, bioluminescent garden, its scales shimmering with iridescent colors. The scene is bathed in the soft, ethereal light of the setting sun. Rendered in a detailed matte painting style, with deep colors, fantastical elements, and intricate details, reminiscent of fantasy concept art trending on Artstation."

Elaborate → Simple:

• Input: "Simplify this prompt: Hyperrealistic 8K render of a majestic phoenix rising from crystalline flames, its feathers crafted from pure starlight, soaring above an ancient mystical forest at dawn with volumetric lighting"
• Output: "A phoenix flying over a forest at sunset"

Training Details

• Base Model: t5-small
• Training Samples: 53,372 bidirectional pairs
• Epochs: 3
• Saturation Control: Applied bias reduction techniques
• Task Balance: 25K elaborate→simple + 24K simple→elaborate

Limitations

• Trained primarily on English prompts
• May occasionally repeat tokens (use repetition_penalty=1.2)
• Optimized for art generation prompts, may not work well for other domains
