    USearch Images demo in 200 lines of Python▲9

    Hey everyone! I am excited to share updates on four of my & my teams' open-source projects that take large-scale search systems to the next level: USearch, UForm, UCall, and StringZilla. These projects are designed to work seamlessly together, end-to-end—covering everything from indexing and AI to storage and networking. And yeah, they're optimized for x86 AVX2/512 and Arm NEON/SVE hardware. USearch [1]: Think of it as Meta FAISS on steroids. It's now quicker, supports clustering of any granularity, and offers multi-index lookups. Plus, it's got more native bindings than probably…

    Natrul AI▲12

    Hey everyone, we just opened the beta for Natrul AI. It’s a lightweight way to add autocomplete, search, content enhancement, and context retrieval to your app. Everything runs on your own content. You stay in control of your data, and it doesn’t require any extra setup. We're also running a 48-hour hackathon from July 11 to 13 with a $500 prize. It's free to join and a good chance to try the API in something small. Would love your feedback, ideas, or edge cases. Curious to see how it fits into whatever you're building. Check it out: https://natrul.ai For those interested, we also…

    Towards agentic Graph RAG: Enhancing graph retrieval with vector search▲6

    In this post, we document the results of some experiments comparing vanilla Graph RAG (just a single pass of text2cypher) vs. a router agent Graph RAG approach that can call vector search tools alongside text2cypher. The routing agent uses an LLM to decide which vector search tool to call, depending on the terms identified in the question, and it works quite well. The results show that recent frontier LLMs like `gpt-4.1` and the trusty workhorse `gemini-2.0-flash` produce great quality Cypher reliably and reproducibly, with some prompt engineering to ensure that the graph schema is formatted…
