衡宇 发自 麦蒿寺 量子位 | 公众号 QbitAI 马斯克xAI人员大动荡，并没有妨碍它家新模型发布。 他在上对近十条Grok 4.2的夸夸推文又是点赞又是转发。 每一条都藏不住对自家新baby的认同和支持。 不仅如此，他还亲自发推公关： 公测将持续到下个月。公测结束后，Grok 4.2将比Grok 4快得多，也聪明得多。 我们知道目前仍有许多bug需要修复和改进，每天都在debug中～ 据了解， Grok 4.2的底层架构具备每周自我迭代的能力，以后每周将更新一次 。 风口浪尖上， Grok 4.2突然上线了——不过是公测Beta版 。 对比如今动辄数万亿参数的模型方阵，Grok 4.2的参数仅有500B，略显克制。 或许也是因为如此， Grok 4.2的市场和用户反馈呈现出一种诡异的两极分化 ：连连盛赞者亦有之，骂骂咧咧者有之。 面对那部分排山倒海的质疑声， 老马这位一向自信爆棚的硅谷狂人也有点坐不住 。 Grok 4.2公测版什么样？ 关于Grok 4.2，其实早有预告。 回顾Grok 4.2的诞生历程，可谓是一部标准的"鸽王进化史"。 去年12月起，马斯克就开始在上频繁预热 ，多次提到"3–4 周内 ...
