Top 3 C++ rag Projects

rag

  • infinity

    The AI-native database built for LLM applications, providing incredibly fast full-text and vector search

    • Project mention: Better RAG Results with Reciprocal Rank Fusion and Hybrid Search | news.ycombinator.com | 2024-05-30

    Within our open source RAG product RAGFlow(https://github.com/infiniflow/ragflow), Elasticsearch is currently used instead of other general vector databases, because it can provide hybrid search right now. Under the default cases, embedding based reranker is not required, just RRF is enough, while even if reranker is used, keywords based retrieval is also a MUST to be hybridized with embedding based retrieval, that's just what RAGFlow's latest 0.7 release has provided.

    On the other hand let me introduce another database we developed, Infinity(https://github.com/infiniflow/infinity), which can provide the fastest hybrid search, you can see the performance here(https://github.com/infiniflow/infinity/blob/main/docs/refere...), both vector search and full-text search could perform much faster than other open source alternatives.

    From the next version(weeks later), Infinity will also provide more comprehensive hybrid search capabilities, what you have mentioned the 3-way recalls(dense vector, sparse vector, keyword search) could be provided within single request.

  • LintDB

    Vector Database with support for late interaction and token level embeddings.

    • Project mention: Show HN: LintDB: a vector database for late interaction retrieval | news.ycombinator.com | 2024-04-05

    - Multi-tenant support.

    We're seeing new research on bitvector searching and late interaction, and we want to be the first ones to support it. Our roadmap also includes adding explainability to the results, which is possible thanks to late interaction.

  • instinct.cpp

    instinct.cpp provides ready to use alternatives to OpenAI Assistant API and built-in utilities for developing AI Agent applications (RAG, Chatbot, Code interpreter) powered by language models. Call it langchain.cpp if you like.

    • Project mention: Parallel function calling agent without OpenAI | news.ycombinator.com | 2024-05-19
