This month, OpenAI announced their Codex app and my coworkers were asking questions. So I downloaded it, and as a test case for the GPT-5.2-Codex (high) model, I asked it to reimplement the UMAP algorithm in Rust. UMAP is a dimensionality reduction technique that can take in a high-dimensional matrix of data and simultaneously cluster and visualize data in lower dimensions. However, it is a very computationally-intensive algorithm and the only tool that can do it quickly is NVIDIA’s cuML which requires CUDA dependency hell. If I can create a UMAP package in Rust that’s superfast with minimal dependencies, that is an massive productivity gain for the type of work I do and can enable fun applications if fast enough.

三份报告叠在一起，拼出的结论只有一个：AI的上半场打完了。谁的模型更大、算力更强，这场军备竞赛几乎已经没有悬念。真正的战争，是下半场——谁能把AI嵌进真实的行业里，谁能解决那些又脏又难、但价值巨大的落地问题。
