Optical Context Compression Is Just (Bad) Autoencoding

arXiv — cs.LGThursday, December 4, 2025 at 5:00:00 AM
  • DeepSeek-OCR has demonstrated that rendered text can be reconstructed with high fidelity from a limited number of vision tokens, raising interest in vision-based context compression for language models. However, the evaluation of these representations' effectiveness in language modeling remains untested, leading to skepticism about their practical utility.
  • The findings challenge the perceived advantages of vision-based compression, suggesting that simpler methods, such as parameter-free mean pooling and learned hierarchical encoders, can achieve comparable or superior results in both text reconstruction and language modeling.
  • This development highlights ongoing debates in the AI community regarding the efficacy of complex models versus simpler alternatives, as well as the broader implications for vision-language integration, particularly in addressing challenges like text recognition in fragmented forms and enhancing model performance across various applications.
