This database stores 60M docs in 6 GB #aiagents #ai #opensource #vectordatabase #leann #claude LEANN is a vector database that skips storing every embedding. It keeps a pruned graph and recomputes embeddings only for the chunks on your search path. Their paper claims 97% less storage with the same search quality, all running locally on your laptop. In this Short: - What a vector database is (in plain words) - Why normal ones get huge: 201 GB for 60M chunks - LEANN's trick: store less, compute on demand - The numbers: 6 GB, 79 MB for emails - Why it's popular and what it changes Repo: StarTrail-org/LEANN Paper: arxiv.org Install: uv pip install leann Numbers are from the project's README (storage table + a 30-task Claude Code benchmark vs BM25).

PixelRAG by Berkeley researchers replaces fragile text parsing with pixel-native search. By rendering web pages and PDFs into visual screenshot tiles, it lets VLM agents retrieve and read actual document layouts. StarTrail-org/PixelRAG

LEANN省下磁盘，查询要等多久？ #Shorts UC Berkeley 的 LEANN Explaine 用约 4 GB 索引达到与 HNSW 相同的 25.5% 问答准确率，但语义检索需 2.48 秒。 LEANN 是 UC Berkeley Sky Computing Lab 开发的开源向量索引，不是大语言模型；它这次展示的关键变化，是不再把完整的文本嵌入向量长期存进索引，而是在查询时按需重算。对想在本地给文档、邮件或代码库做语义检索的开发者来说，这可能大幅降低存储门槛，但省下的磁盘空间会转化成查询计算和等待时间。 论文评测的一个设置中，LEANN 用约 4 GB 索引达到与 HNSW 相同的 NQ 下游问答准确率 25.5%，但检索耗时是 2.48 秒，对比 HNSW 的 0.05 秒。注意，90% Recall@3 是检索目标，不是问答准确率；论文结果来自团队自己的基准评测，现有材料没有第三方复现。建库仍需先为所有文本块生成嵌入，CPU 延迟也没有公开数据。想试用时，可以先用 `uv pip install leann` 安装，再拿自己的语料对比索引大小、召回率和端到端延迟，判断它适不适合低频、本地检索场景。#LEANN #向量检索 #RAG #人工智能 ——— 🔗 论文：arxiv.org 🔗 GitHub：StarTrail-org/LEANN 这类底层拆解如果对你有用，订阅 + 打开小铃铛，新一期更新第一时间到你这儿。 ⏱ 章节 00:00 压缩幅度惊人，但LEANN的主张不是“又小又快”：它把存储优势和查询变慢同时 00:34 LEANN的关键变化不是取消向量计算，而是不再长期保存全部完整向量。 00:44 查询不是重算全库，而是先筛候选，再为搜索实际触及的节点重算嵌入。 01:14 在指定NQ评测中，LEANN达到与HNSW相同的下游准确率，但检索阶段明显更 01:35 LEANN更像是存储受限场景的选择，而不是低延迟检索的通用替代品；实际是否划 🔗 资源 · 代码：StarTrail-org/LEANN #Shorts 🔎 从本视频继续选型： zhiyong.dev --- 🔎 相关 AI 工具、模型与应用： zhiyong.dev
