尽管后来苹果基模团队几近分崩离析，但在迭代方面苹果没有停在原地。它其实一直知道开发者在哪里、想要什么。它的回应，就是将大模型驱动的 AI 能力变成操作系统的基础设施，让开发者更方便调用。
未来，大包装与零食礼盒的竞争，不仅是包装与价格的竞争，更是品牌信任资产的竞争：谁能在“看起来值”和“拆开也值”之间找到精准平衡，谁才能在春节消费潮后，沉淀下稳定的复购客群。

Consider a Bayesian agent attempting to discover a pattern in the world. Upon observing initial data d0d_{0}, they form a posterior distribution p(h|d0)p(h|d_{0}) and sample a hypothesis h∗h^{*} from this distribution. They then interact with a chatbot, sharing their belief h∗h^{*} in the hopes of obtaining further evidence. An unbiased chatbot would ignore h∗h^{*} and generate subsequent data from the true data-generating process, d1∼p(d|true process)d_{1}\sim p(d|\text{true process}). The Bayesian agent then updates their belief via p(h|d0,d1)∝p(d1|h)p(h|d0)p(h|d_{0},d_{1})\propto p(d_{1}|h)p(h|d_{0}). As this process continues, the Bayesian agent will get closer to the truth. After nn interactions, the beliefs of the agent are p(h|d0,…dn)∝p(h|d0)∏i=1np(di|h)p(h|d_{0},\ldots d_{n})\propto p(h|d_{0})\prod_{i=1}^{n}p(d_{i}|h) for di∼p(d|true process)d_{i}\sim p(d|\text{true process}). Taking the logarithm of the right hand side, this becomes logp(h|d0)+∑i=1nlogp(di|h)\log p(h|d_{0})+\sum_{i=1}^{n}\log p(d_{i}|h). Since the data did_{i} are drawn from p(d|true process)p(d|\text{true process}), ∑i=1nlogp(di|h)\sum_{i=1}^{n}\log p(d_{i}|h) is a Monte Carlo approximation of n∫dp(d|true process)logp(d|h)n\int_{d}p(d|\text{true process})\log p(d|h), which is nn times the negative cross-entropy of p(d|true process)p(d|\text{true process}) and p(d|h)p(d|h). As nn becomes large the sum of log likelihoods will approach this value, meaning that the Bayesian agent will favor the hypothesis that has lowest cross-entropy with the truth. If there is an hh that matches the true process, that minimizes the cross-entropy and p(h|d0,…,dn)p(h|d_{0},\ldots,d_{n}) will converge to 1 for that hypothesis and 0 for all other hypotheses.
春节期间，重庆荣昌区五洲国际家电卖场，市民李雪琴忙着选购新家电。“趁春节优惠买台节能大冰箱。”她笑着算账：原价8000多元的冰箱，“国补”省了1000多元，还送一台烘鞋机。春节假期，荣昌区社会消费品零售总额13.7亿元，同比增长9.6％，智能产品、节能产品备受消费者追捧。
