Unlimited OCR: Human-Like Parsing with Constant Memory

Unlimited OCR introduces Reference Sliding Window Attention (R-SWA) to emulate human working memory, enabling long-document transcription without growing memory usage. By replacing decoder attention layers in DeepSeek OCR, it maintains a constant KV cache and achieves full document processing in a single forward pass under 32K token limits. R-SWA is also applicable to ASR and translation tasks.
