    **Key features include:**
    - **Bilingual understanding**: Supports high-precision interpretation of Chinese and English prompts, generating culturally nuanced images.
    - **Text rendering**: Uses Glyph-Aligned ByT5 for flexible character-level text rendering, reducing text distortion and improving aesthetics, especially for traditional Chinese styles.
    - **Multi-resolution generation**: Employs a scaled DiT architecture to generalize untrained resolutions and support varied aspect ratios.
    - **RLHF optimization**: Enhances image-text alignment, aesthetics, structural correctness, and text rendering through self-developed reward models.

    **Innovations include:**
    - **Data construction**: Four-dimensional topology (quality, distribution, knowledge, enhancement) with smart annotation.
    - **Pretraining**: Self-developed LLM for bilingual alignment and upgraded SD3 MMDiT architecture.
    - **RLHF**: Four-stage optimization with three reward models.
    - **Evaluation**: Bench-240 benchmark tests for image-text matching, structure accuracy, and aesthetics, outperforming competitors in bilingual tasks.
