在 Agent Routing 之外，Decision Models 还有什么有意思的应用场景？

小而美的 Drex 给出了一个很有意思的 use case: Document Processing

Nace AI 将 Drex 集成到 Perception pipeline 中，通过 decision model，识别并辅助修正 document parsing errors，让更可靠的数据进入下一层 AI Agent。

Perception + Drex 的 Parse Index 位居 parsing leaderboard 榜首，表现优于 GPT-6 Astra，Claude Opus 4.7 和 Mistral OCR。

在 RealDocBench 上实现 38% faster page corrections，进一步提升了文档处理效率。

Decision Models beyond Agent Routing

值得关注！
