Researchers are developing novel methods for compressing lengthy text into visual representations to improve the efficiency of Retrieval-Augmented Generation (RAG) systems. One approach, RAGOCR, uses query-aware dynamic resolution to balance compression rates and information fidelity, significantly boosting accuracy while reducing token input. Another line of research focuses on evaluating these Vision-Text Compression (VTC) methods, proposing a decoupled framework that separates VTC quality from downstream model capabilities to ensure faithful text preservation. A self-supervised alignment framework called SPIRAL further enhances VTC by integrating rendered-image representations with native-text semantics, achieving performance close to native text input. AI
