Artificial Analysis: Grok 4.7 buys its two-point score gain by burning 81k output tokens per task
Artificial Analysis·high signal
Artificial Analysis measured Grok 4.7 (xhigh) at 46 on its Intelligence Index using roughly 81k output tokens per task, against 38k for Grok 4.6 (xhigh) and 27k for GPT-6 Astra (max), and clocked it at about 7.1 minutes per task. Since per-token pricing is unchanged from 4.6, the practical effect is that a task that cost one unit now costs about two. The one clean win is hallucination rate, down to 29% from 34%, with accuracy flat at 47% versus 48%.
