    • 3D Scene Consistency Check: Analyzes model proportions and lighting from multiple perspectives

    Professional Document Processing

    • Format Optimization: Adjusts PPT font sizes and Excel border styles automatically
    • Content Validation: Detects numerical inconsistencies in financial reports
    • Aesthetic Evaluation: Scores document visuals based on design principles and suggests color schemes

    Financial Research Support

    • Visual Report Analysis: Extracts key data from PDF financial statements to generate charts
    • Research Structuring: Converts unstructured reports into searchable databases
    • Multimodal Retrieval: Enables joint text-chart queries for rapid information location

    Technological Cost Efficiency

    The model achieves cost optimization through three innovations:

    1. Parameter Efficiency: 1/8 inference cost vs. industry average through 5.6% parameter activation
