你应该会注意到你的时间线内容质量几乎每周都在快速提升，但有时候也会出现两步前进、一部后退的情况。 我们也正在把广告推荐系统切换为与自然内容相同的 Grok/AI 系统，因此广告的质量也将会有极大幅度的提升。 You should notice rapid improvements in the quality of your timeline almost every week, but there will be two steps forward and one step back at times. We are also switching advertising recommendations to use the same Grok/AI system as organic posts, so quality of ads will get radically better.
