Two frontier OCR releases land the same week: Baidu's Unlimited-OCR and Mistral OCR 4.
Story
Baidu's open-source Unlimited-OCR hit ~343 points on HN, pitched as one-shot parsing of long multi-page documents instead of page-at-a-time chunking. (GitHub) Mistral OCR 4 drew ~288 points the same week. (Mistral) Document parsing is still the core bottleneck for RAG and agentic ingestion, and long-horizon OCR that holds context across a whole document is a real quality upgrade. PaddlePaddle's PP-OCRv6 (50 languages, 1.5M to 34.5M params for edge) rounds out a heavy OCR week. Benchmark against your own documents before swapping pipelines, accuracy claims never survive contact with messy real PDFs.
