好吃,不等于好种。这株看似寻常的禾本科作物,生育期长达220天至270天,从秋种到夏收,可谓“种在冰上、收在火上”。在山东省沂南县张庄镇前汉沿村,去年10月底以来,种粮大户刘增升没少操心:播前把800多亩地深翻了一遍,又拌了种子,播后镇压了一次,给弱苗喷施叶面肥……一直到开春浇下返青水,眼看苗情转好,他才宽下心。

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.
