LlamaIndex 搞了个 Parse Gateway，能自动识别 PDF 里哪些页简单、哪些复杂，简单页免费快解析，复杂页才走高级管道，还能让智能体自己选层级，省成本又不丢精度。
LlamaIndex 推出了 Parse Gateway，一个智能 PDF 解析管道。它利用 LiteParse 的 is_complex 功能逐页评估复杂度（扫描页、表格、乱码、嵌入图片等），简单页面在进程中免费解析，困难页面自动路由到更强大的 LlamaParse 层级。支持 MCP 服务器，智能体可自主选择解析层级。在降低解析成本的同时不牺牲准确性。

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 built 𝗣𝗮𝗿𝘀𝗲 𝗚𝗮𝘁𝗲𝘄𝗮𝘆 to fix that. It uses LiteParse's 𝘪𝘴_𝘤𝘰𝘮𝘱𝘭𝘦𝘹 functionality to estimate complexity page-by-page and routes each page to the right tier based on why it's complex (scanned, sparse text, garbled encoding, vector text, embedded images) and how severely. Simple pages get parsed for free, in-process. Genuinely hard pages get routed to more capable LlamaParse tiers. No manual heuristics, no flat one-size-fits-all pipeline. And it's also available as an MCP server, so your agents can estimate complexity and choose a parsing tier themselves! The result: you stop paying premium prices for pages that never needed it, without sacrificing accuracy on the ones that d llamaindex.ai/blog/parse-gat… ttps://t.co/K5 github.com/run-llama/pars… https://t.co/Gl0Dggv8qn 💬 3 🔄 2 ❤️ 10 👀 837 📊 5 ⚡
