Kimi K3 tops global AI model rankings, Musk says Grok 4.6 will beat it

Moonshot AI's open-source model Kimi K3 recently topped global rankings, sparking industry buzz. On July 18, Elon Musk posted on social media that his company xAI is training a 2-trillion-parameter model, set to finish initial training next week, outperforming the current 1.5-trillion version and potentially beating Kimi K3. This model, Grok 4.6, will have similar speed and token efficiency to the existing version.

Moonshot AI replied on Weibo, inviting Musk to join the "2-trillion+ club." xAI hasn't announced the official release or full specs of Grok 4.6 yet. Earlier, xAI launched Grok 4.5 on July 9, its first model for coding and agent tasks, which Musk called an "Opus-level model."
