你的 AI Agent 需要一个「三层记忆」,而不是一个聊天记录
去年我开始给 Hermes Agent 搞知识库。最初的想法很简单:装个向量数据库,查资料时能命中就行。结果跑了一圈发现—— 纯向量检索在 Agent 场景下不够用 。 有些记忆是你能精确描述的("帮我查上次那篇讲 gbrain 孤页的文章"),有些记忆你只记得个大概("有个关于知识图谱的……"),有些记忆你甚至不知道你该知道什么("我有哪些笔记是没关联起来的?")。一个检索策略覆盖不了这三种场景。 这就是 Knowledge-and-Memory-Management v0.0.2 解决的问题。 三层不是为了「多」,而是为了互补 项目是目前运行在 Hermes Agent 生态里的扩展层,底座是 hermes-memory-installer 提供的 gbrain(知识图谱)+ Hindsight(向量记忆)。KMM 在这上面加了四组模块:采集、笔记/RAG、云盘同步、知识增广。 其中最有工程价值的设计是 三层跨层召回 : FTS5 全文搜索 → 精确命中,知道你要什么 Hindsight 向量语义 → 模糊配匹,关键词不够时靠语义 gbrain 知识图谱 → 关系探索,你不知道但相关的节点 lightweight_recall.py 把这三级串联成一条管线——先查本地 SQLite FTS5,命中直接返回;没命中走 Hindsight 的文本嵌入匹配;还不满意就用 gbrain 展开知识图谱的邻接节点。 代码在 $AGENT_HOME/scripts/lightweight_recall.py ,调用并不复杂: # 三层召回示例 from knowledge_collector.knowledge_management import KnowledgeManager km = KnowledgeManager () # 一次调用,三级自动回退 results = km . tiered_search ( query = " Agent 记忆系统设计 " , tiers = [ " fts5 " , " hindsight " , " gbrain " ], limit_per_tier = 5 ) for tier , hits in results . items (): print ( f " [ { tier } ] { len ( hits ) } 条结果 " ) for h in hits [: 2 ]: print ( f " → { h [ ' title ' ] } ( { h [ ' relevance ' ] : . 2 f } ) " ) FTS5 走 SQLite 内置,零依赖;Hindsight 端口 8890;gbrain 端口 8787。每层都是独立的可降级——向量服务挂了,全文搜索照样能跑。 真正干活的是这 40+ 工具 三层召回是检索层,采集层才是让知识库有东西可喂的入口。项目塞了 40+ 采集分析工具,按类型分: 网页采集(9 引擎) :Scrapling 做反检测,Crawl4AI 做智能路由,爬公众号不走弯路 视频采集(12 工具) :yt-dlp 拖流 → Whisper ASR 转写 → PaddleOCR 关键帧,抖音/YouTube 一把抓 文档分析(9 工具) :SenseNova 三件套(PDF/PPT/Word)处理扫描件和复杂排版 书籍精炼(6 工具) : book_to_skill 管线把 PDF/EPUB 拆成结构化 Skill + KMM 笔记 每周日凌晨还有个 knowledge_discovery.py 爬起来,扫 OneDrive 上的新笔记,自动录入 gbrain,顺便跑孤页链接修复——这些属于「你不需要知道它存在,但它让系统不腐烂」的基建。 几个工程取舍 不做纯向量优先 :FTS5 第一级是因为延迟低(毫秒级),且精确关键词匹配在查代码、查配置时远好于语义 gbrain 孤页处理是刚需 :知识图谱不加链接维护,三个月后 90% 的页面都成孤岛(亲测 10,666 页从 1,716 个孤页降到 33) 采集优先于检索 :没有好的采集管线,检索再强也是对着空库跑——项目把采集工具堆到 40+ 不是炫技 适用场景 如果你的 Agent 需要从多个来源(网页、视频、文档、公众号)持续摄入知识,并且知识需要在精确搜索、模糊回忆和关系探索三个维度上都能命中——三层模式值得一试。不需要全部部署,只接 FTS5 + gbrain 两层也能跑,每层独立可降级。 GitHub: mage0535/Knowledge-and-Memory-Management ,MIT 协议。

Agents write code, but they don't remember
Code generation is solved, but memory isn't. Here's an argument for why the SDLC is inverting with intent becoming the spine and code becoming a layer you drill into, explaining what teams lose every time an agent's reasoning disappears.
Nvidia says its AI data center design runs hotter to use a lot less water
Public pushback against data centers has emphasized their water and energy consumption, and now Nvidia is highlighting its claim that the Rubin generation reference design for a fully liquid-cooled data center has "eliminated massive amounts of power usage and pretty much all water usage." Still, it doesn't address all of the concerns around AI data […]
