Many people reading this will call bullshit on the performance improvement metrics, and honestly, fair. I too thought the agents would stumble in hilarious ways trying, but they did not. To demonstrate that I am not bullshitting, I also decided to release a more simple Rust-with-Python-bindings project today: nndex, an in-memory vector “store” that is designed to retrieve the exact nearest neighbors as fast as possible (and has fast approximate NN too), and is now available open-sourced on GitHub. This leverages the dot product which is one of the simplest matrix ops and is therefore heavily optimized by existing libraries such as Python’s numpy…and yet after a few optimization passes, it tied numpy even though numpy leverages BLAS libraries for maximum mathematical performance. Naturally, I instructed Opus to also add support for BLAS with more optimization passes and it now is 1-5x numpy’s speed in the single-query case and much faster with batch prediction. 3 It’s so fast that even though I also added GPU support for testing, it’s mostly ineffective below 100k rows due to the GPU dispatch overhead being greater than the actual retrieval speed.
，这一点在Safew下载中也有详细论述
但这些顾虑最终没有改变任何事情。
入园适应期2025年9月1日，对孩子和我们一家来说都是重要的一天。这是孩子4年来，第一次离开我们身边，进入一个全新的环境。学校要求7点50左右到校（因为要吃早饭）；早上7点叫孩子起床，但是孩子好像知道什么，不愿意起，要让妈妈一起起床，让我们两个人一起送她去幼儿园。
