BlueVetaUpright is a specialized API for detecting and correcting the semantic orientation of products in photographs, achieving 99.02% accuracy on cardinal rotations and outperforming GPT-4V, Gemini, and Claude by significant margins (e.g., +15.2 percentage points against ChatGPT). The system combines multiple purpose-built components to identify correct rotation angles and estimate confidence, addressing a key gap in product-image automation pipelines where metadata-based rotation cannot detect sideways photographed items.
