TL;DR · AI 摘要

文档OCR路由器通过智能路由实现多模式解析，显著提升复杂文档处理效率。

核心要点

  • 使用LiteParse的is_complex参数可自动识别页面复杂度并路由解析模式
  • 扫描图像/表格采用成本效益模式，乱码文本需VLM处理，图表需深度视觉解析
  • LlamaParse提供针对复杂页面的视觉语言模型解析方案

The next step is figuring out what the relevant VLM modes are to parse varying page complexities. That's well served by LlamaParse!

Not every page in your PDF needs the same treatment. A scanned cover, a dense table, a clean text page, a figure-heavy diagram.... most parsing pipelines throw all of them at the same parser, forcing a tradeoff between cost, speed, and accuracy across the whole document. We
