SpaceXAI's Grok 4.6 Scores 61 on the Artificial Analysis Intelligence Index

SpaceXAI's Grok 4.6 has scored 61 on the Artificial Analysis Intelligence Index, placing it at the frontier of AI performance alongside OpenAI's GPT-5.6 Sol and behind only Anthropic's Claude models. The model demonstrates particularly strong agentic performance capabilities while maintaining the same pricing as its predecessor ($2/$6 per million tokens), making it 60% cheaper than competing frontier models. Grok 4.6 achieved a 5-point improvement over Grok 4.5 just one month after release and excels in real-world knowledge work tasks, customer service, and terminal-based software applications.
