Elon Musk says xAI's Grok 4.6 "might be able to exceed Kimi"

Chinese startup Moonshot AI recently released its open-weight Kimi K3 model, which drew heavy interest and temporarily halted new subscriptions due to computing limits. The launch stirred online debates in China about the nation’s standing in AI and whether open-weight systems can match proprietary U.S. models. On X, Elon Musk announced that his company xAI’s next-generation Grok 4.6—a 2-trillion-parameter model—had entered its last training phase and could outperform Kimi while matching Grok 4.5’s speed and efficiency. Moonshot AI’s official Weibo account replied with a brief welcome to the “2 Trillion+ Club,” a response widely praised online as confident and non-confrontational. The exchange highlights growing competition between U.S. and Chinese AI developers and the rising importance of both performance and computing efficiency.
