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.

Despite an ultimatum from Defense Secretary Pete Hegseth, Anthropic said that it can't "in good conscience" comply with a Pentagon edict to remove guardrails on its AI, CEO Dario Amodei wrote in a blog post. The Department of Defense had threatened to cancel a $200 million contract and label Anthropic a "supply chain risk" if it didn't agree to remove safeguards over mass surveillance and autonomous weapons.

全球第四大汽车制造商Stellantis在2025年经历了一场代价沉重的战略转身。该公司2月26日发布的财报显示，全年净亏损高达223亿欧元（以当前汇率计算约为1802亿人民币），这主要源于下半年启动业务重组产生的254亿欧元非常规费用。尽管全年数据承压，但下半年运营已出现回暖信号，营收恢复增长，现金流状况较上半年大幅改善。这家拥有Jeep、玛莎拉蒂、标致、雪铁龙等14个品牌的汽车巨头，在2025年净营收录得1535亿欧元，同比微降2%。该公司解释称，外汇因素影响及上半年新车价格下降是影响营收的主要原因。，推荐阅读同城约会获取更多信息
