截至2026年，Sun City的医疗服务已经实现全面覆盖——从急诊、专科护理，到长期护理、预防保健，老人的所有医疗需求，基本都能在社区内解决。而Banner Health依然是主要服务提供者，社区基金会则继续提供捐赠支持，形成了“专业管理+社区支撑”的稳定模式。

2026年2月24日，宇树发布了全新四足机器人Unitree As2。这款“可载人”的四足机器人，动力性能约为前代主力产品Go2的两倍，自重18kg，峰值扭矩达90N·m，极限速度5m/s。续航方面，空载超4小时，背15kg负载仍能连续走超13公里，还做了IP54防雨设计。
The main lesson I learnt from working on these projects is that agents work best when you have approximate knowledge of many things with enough domain expertise to know what should and should not work. Opus 4.5 is good enough to let me finally do side projects where I know precisely what I want but not necessarily how to implement it. These specific projects aren’t the Next Big Thing™ that justifies the existence of an industry taking billions of dollars in venture capital, but they make my life better and since they are open-sourced, hopefully they make someone else’s life better. However, I still wanted to push agents to do more impactful things in an area that might be more worth it.

This works. From my tests with the algorithms, Codex can often speed up the algorithm by 1.5x-2x, then Opus somehow speeds up that optimized code again to a greater degree. This has been the case of all the Rust code I’ve tested: I also ran the icon-to-image and the word cloud crates through this pipeline and gained 6x cumulative speed increases in both libraries.
