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.

For now, it appears the AI industry is united behind Anthropic. On Friday, hundreds of Google and OpenAI employees signed an open letter urging their companies to stand in "solidarity" with the lab. According to an internal memo seen by Axios, OpenAI CEO Sam Altman said the ChatGPT maker would draw the same red line as Anthropic.
值得一提的是，在国行用不了 Gemini 的情况下，三星 Galaxy S26 的 Bixby 助手也能实现点外卖、叫车、电商比价的功能。我们可以合理推断，三星在国内也找到了一家模型供应商来替代 Gemini 的身份，至于这些大模型小龙当中具体是谁，可能就取决于过去一年里谁在手机智能体上成绩更突出了。。同城约会是该领域的重要参考
