用 Nova 2 Lite 做粗提取，Claude Sonnet 4.6 做精准匹配，文档数字化省心又省钱。
AWS 博客展示如何用 Amazon Nova 2 Lite 和 Claude Sonnet 4.6 构建两模型管道，用于扫描文档的数字化。Nova 2 Lite 在单次调用中完成多模态提取（检测照片、提取姓名坐标、返回页面元数据）。Claude Sonnet 4.6 根据版面布局进行空间推理，将姓名和面孔匹配。该管道在 Amazon Bedrock 上运行，通过分工降低总处理成本。
Pair Nova 2 Lite with Claude for cost-optimized document processing
In this post, we show how pairing Amazon Nova 2 Lite with Anthropic’s Claude Sonnet 4.6 delivers an efficient solution for digitizing scanned documents at scale. We built a two-model pipeline on Amazon Bedrock for digitizing scanned yearbook pages. Amazon Nova 2 Lite handles native multimodal extraction in a single call: detecting photos, extracting visible names with coordinates, and returning page-level metadata. Claude Sonnet 4.6 then performs spatial reasoning to match names to faces based on page layout.
