SpaceXAI debuts Grok 4.6, overtaking Kimi K3's performance and matching GPT-5.6 Sol for world's third best on Artificial Analysis
Summary
Elon Musk's company SpaceXAI, formerly known as xAI, has released Grok 4.6, its latest frontier AI model, with a focus on long-running agents, coding and knowledge work — and a pricing strategy designed to make those workloads cheaper to run. The model scores 61 on the third-party Artificial Analysis Intelligence Index, surpassing the popular open weights Chinese model from Moonshot, Kimi K3, and tying rival OpenAI's GPT-5.6 Sol Max and improving five points over Grok 4.5 High. Anthropic's Claude Opus 5 and Fable 5 occupy the number one and two spots, respectively.
