Grok 4.6 returns SpaceXAI to the intelligence frontier, matching GPT-5.6 at a fraction of the cost
SpaceXAI's Grok 4.6 Scores 61 on the Artificial Analysis Intelligence Index
SpaceXAI's Grok 4.6 scores 61 on the Artificial Analysis Intelligence Index, joining the frontier alongside GPT-5.6 Sol and behind only Anthropic's Claude models. It gains 5 points over Grok 4.5 and 23 over Grok 4.3. Grok 4.6 excels in agentic tasks, achieving top-tier scores on GDPval-AA v2, τ³-Banking, and Terminal-Bench v2.1. Pricing remains at $2/$6 per 1M tokens, 60% below rivals, with a cost per task of $0.84, placing it on the Pareto frontier. On long-horizon tasks (AA-Briefcase), it scores 1577 Elo, using half the turns and a quarter of the input tokens of Claude Opus 5.
Holding headline pricing flat across a generation is unusual at the frontier, where intelligence gains have typically been accompanied by price increases.
