Pros
- +专门针对 LLM 优化的输出格式，确保转换后的 Markdown/JSON 能够被 AI 模型高质量理解和处理
- +支持复杂 PDF 文档的结构化解析，保持表格、图像和文本布局的完整性
- +提供 Python SDK 和 Web 应用双重接口，既适合程序化集成也支持交互式使用
- +Excellent handling of complex document layouts including equations, tables, handwriting, and multi-column formats with natural reading order preservation
- +Cost-effective processing at under $200 per million pages, making it economical for large-scale dataset creation
- +Continuous model improvements with recent releases showing significant performance gains and reduced hallucinations on blank documents
Cons
- -主要专注于 PDF 处理，对其他文档格式的支持可能有限
- -复杂文档的处理质量可能依赖于原始文档的质量和结构清晰度
- -大规模批量处理时可能需要考虑计算资源和处理时间的平衡
- -Requires GPU resources due to 7B parameter model, making it computationally intensive and potentially expensive to run
- -May require multiple retries for some documents to achieve optimal results
- -Limited to image-based document formats (PDF, PNG, JPEG) and requires technical expertise for setup and optimization
