婚恋和资源共享市场，到底该用传统搜广推还是 AI 推荐算法？
Published:
我和朋友最近在讨论这个问题。朋友说想拿 AI 来做婚恋市场的匹配，我觉得在样本量小的情况下，这完全可行——甚至根本不需要搭任何搜广推系统。你直接问大语言模型，把几个用户的简历丢进去，让它排序就好了，整个过程非常简单。

Clear Plus Airport Experience: Money, Privilege, and Market Regulation
Published:
I want to rewrite this article. What I want to express is that I feel pleasantly surprised because I rarely use money to enjoy privileges. This privilege was actually obtained for free through my Uber annual membership. Originally, I wouldn’t have paid over a hundred dollars a year for this service. It was only because Uber’s annual membership gave me this privilege for free that I had the opportunity to experience this privilege that money can’t necessarily buy. Therefore, I’m quite pleasantly surprised.
Clear Plus 体验：金钱、特权与市场调节
Published:
我感到很惊喜，因为我之前很少用金钱来享受特权。这个特权其实也是因为我有了 Uber 的年费会员，才能够免费体验到的。本来因为它一年需要一百多美金，我是不会单独去花钱付这个费用的。正是因为 Uber 的年费会员免费赠送了我这个特权，我才有机会体验到这个用金钱都买不到的特权。
