 # RealGen: Photorealistic Text-to-Image Generation via Detector-Guided Rewards
-Detection Models:
+
+The model presented in the paper [RealGen: Photorealistic Text-to-Image Generation via Detector-Guided Rewards](https://huggingface.co/papers/2512.00473) proposes a photorealistic text-to-image framework. RealGen integrates an LLM component for prompt optimization and a diffusion model for realistic image generation. It introduces a "Detector Reward" mechanism, which quantifies artifacts and assesses realism using both semantic-level and feature-level synthetic image detectors. This reward signal is leveraged with the GRPO algorithm to optimize the entire generation pipeline, significantly enhancing image realism and detail.

+## Detection Models
+RealGen utilizes specialized detection models to guide its generation process:
 - **Semantic Detector**: Forensic-Chat, a generalizable and interpretable detector optimized from Qwen2.5-VL-7B. It assesses authenticity by analyzing image content (e.g., smooth greasy skin, artifacts in faces/hands, unnatural background blur).
-- **Feature Detector**: OmniAID achieves stable and accurate detection by being pre-trained on large-scale real and synthetic datasets. Feature-level artifacts are primarily associated with frequency artifacts and abnormal noise patterns.
+- **Feature Detector**: OmniAID achieves stable and accurate detection by being pre-trained on large-scale real and synthetic datasets. Feature-level artifacts are primarily associated with frequency artifacts and abnormal noise patterns.
