## AI 摘要

PaddleOCR-VL-1.6是一个升级的紧凑型文档解析模型，基于0.9B参数规模的PaddleOCR-VL-1.5构建。针对前一版本中模型行为不稳定、数据稀疏或监督不可靠的欠优化区域，该模型引入了区域感知数据优化框架进行定向增强，并采用基于精选数据选择和强化学习的渐进式后训练方案。PaddleOCR-VL-1.6在OmniDocBench v1.6上取得了96.33%的新SOTA成绩，展现出与顶尖VLMs的竞争力。

We introduce PaddleOCR-VL-1.6, an upgraded compact document parsing model built upon PaddleOCR-VL-1.5. Although PaddleOCR-VL-1.5 establishes a strong 0.9B baseline, its remaining errors concentrate in under-optimized regions where model behavior is unstable, data coverage is sparse, or supervision is unreliable. Rather than expanding the training corpus indiscriminately, PaddleOCR-VL-1.6 introduces a region-aware data optimization framework that identifies weak regions from the previous model, applies targeted enhancement to these regions, and improves the reliability of supervision signals. It further adopts a progressive post-training recipe based on curated data selection and reinforcement learning, pushing model performance to a higher level through staged optimization. PaddleOCR-VL-1.6 achieves a new state-of-the-art score of 96.33% on OmniDocBench v1.6, demonstrates strong competitiveness against top-tier VLMs, and provides a practical post-training recipe for the PaddleOCR-VL series.
