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.
这在当时是华强北最常见的模式，工厂代工生产（ 不涉及产品核心设计 ），国际用户拿到手贴上自己品牌去卖。货一出海，价格往往能翻好几倍，但这跟代工厂没关系，国内这些工厂赚的，就只是最底层那薄薄一层加工费。
