Vectorize

What it does

Vectorize is a data platform for retrieval augmented generation (RAG). It combines RAG evaluation to identify the best way to vectorize your data with a cloud-scale RAG pipeline engine. Vectorize populates your vector database and keeps your vector data fresh.

Open source agent memory. Your agents learn from mistakes and get better over time. 94.6% on LongMemEval. MIT licensed.

With Hindsight, your agents remember your users and get better at their jobs over time. Open source, MIT licensed. Share what you're building, ask questions, and get help directly from the team. Every other memory system stores facts and retrieves them. That works until your agent encounters the same problem twice and makes the same mistake both times. LongMemEval scores across four memory systems. Peer-reviewed benchmark, independently reproduced. Tell Claude Code or Cursor to add Hindsight. It reads the docs, writes the config, and sets up its own memory. One command. No boilerplate. Works with any MCP-capable agent. Your agent gets remember , recall , and reflect tools automatically.…from vectorize.io

  FastGraphRAG – Better RAG using good old PageRank2024 · github.com · ▲457

  Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that…

  Demystifying Advanced RAG Pipelines2023 · github.com · ▲131

  I've built an advanced RAG (Retrieval-Augmented Generation) pipeline from scratch to demystify the complex mechanics of modern LLM-powered Question Answering systems. This repository features: -- An implementation of a sub-question query engine from scratch to answer complex user questions. -- Illustrative explanations that unveil the inner workings of the system. -- An analysis of the challenges I faced while working with the system, like prompt engineering and cost estimation. -- Qualitative comparison with similar frameworks like LlamaIndex, offering a broader perspective. Key Takeaway:…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
