Grok 4.6 ranks third on the Artificial Analysis Healthcare and Medical Index

XAI's Grok 4.6 ranked third on the Artificial Analysis Healthcare and Medical Index, behind Anthropic's Claude Opus 5 (max) and Claude Fable 5 (with fallback), according to a benchmark weighting clinical reasoning, medical knowledge, and hallucination rates. Grok 4.6 scored 61 on the Artificial Analysis Intelligence Index, up from Grok 4.5's 56, and is priced at $2 per million input tokens and $6 per million output tokens.

Via xai-technologies.com Grok 4.6 ranks third on the Artificial Analysis Healthcare and Medical Index xAI's latest model beats GPT-5.6 Sol and Kimi K3 on a benchmark that weights clinical reasoning, medical knowledge, and hallucination rates xAI’s Grok 4.6 has landed in third place on the Artificial Analysis Healthcare and Medical Index, sitting behind only Claude Opus 5 max and Claude Fable 5 with fallback . For a model released around August 12, 2026, breaking into the top three of a specialized medical benchmark this quickly is a meaningful signal about where xAI is focusing its engineering effort. The ranking matters partly because of how the index is constructed. It is not a single-task leaderboard. Medical knowledge accounts for 35% of the score, agentic knowledge work for 25%, non-hallucination rates for 15%, reasoning for another 15%, and agentic customer interaction for the remaining 10. What the numbers say Grok 4.6 scored 61 on the broader Artificial Analysis Intelligence Index, up from the 56 that Grok 4.5 posted. It puts Grok 4.6 on equal footing with GPT-5.6 Sol on the Intelligence Index while outpacing it on the healthcare-specific ranking. Agentic capability accounts for a combined 35% of the total score when you add the knowledge work and customer interaction components together. Grok 4.6 is priced at $2 per million tokens for input and $6 per million tokens for output. A crowded and fast-moving field The models above Grok 4.6 on the index are both from Anthropic. Claude Opus 5 max holds the top position, with Claude Fable 5 with fallback in second. Kimi K3, developed by Moonshot AI, also trails Grok 4.6 on the healthcare ranking. Grok 4.5 scored 56 on the Intelligence Index. Grok 4.6 scored 61. That five-point improvement arrived in a model iteration cycle that, based on the naming convention, does not even represent a full generational leap.
