xAI CEO埃隆 · 马斯克今天在X平台表示，Grok 4.20将在下周发布，相比4.1版改进重大。
作为参考，Grok 4.1发布于去年11 月，继承前代模型敏锐的智能与高可靠性，在创造性、情感理解和协作互动方面实现了重大改进，当时在LMArena文本能力排行榜以1483的Elo分数高居榜首，领先第二名达31分。
更引人注目的是，当时Grok 4.1无需深度思考的“即时响应”版本也以1465的Elo分数位列第二，性能甚至超越了其他所有模型的“全推理”模式。这一成绩相较于前代Grok 4（排名第33位）实现了巨大飞跃，也印证了其在底层能力上的绝对优势。
值得注意的是，Grok 4.1当时还改进了“幻觉”出现率，为用户提供更可靠、更准确的信息。
