Core Viewpoint - The launch of Grok 4.2, despite internal turmoil at xAI, has generated mixed reactions from users, highlighting both praise and criticism for the new model [1][13]. Group 1: Model Release and Features - Grok 4.2 has been released as a public beta version, featuring 500 billion parameters, which is relatively modest compared to other models with trillions of parameters [1]. - The model is designed to self-iterate weekly, allowing for continuous updates and improvements based on real-time feedback [3][9]. - Users must manually select the beta version to use Grok 4.2, which introduces a rapid learning capability [9]. Group 2: User Feedback and Reception - Initial feedback has been polarized, with some users expressing disappointment in the model's performance, particularly in complex logical reasoning tasks [13]. - Critics suggest that Grok 4.2's capabilities may not match those of competitors like OpenAI and Anthropic, raising concerns about its practical effectiveness [13]. - Conversely, some users have praised Grok 4.2 for its coding abilities and multi-modal capabilities, indicating a divide in user experience [14]. Group 3: Elon Musk's Response and Future Plans - Elon Musk has actively defended Grok 4.2 on social media, emphasizing its potential for improvement and future updates [19]. - The current version is described as a "small" model, with plans for medium and large versions to be released later [19].

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 ...
