Grok 4.6 scored 61 on the Artificial Analysis Intelligence Index after its release, matching OpenAI’s GPT-5.6 Sol Max while trailing Anthropic’s leading models, and is priced at $2 per million input tokens and $6 per million output tokens versus Sol Max’s $5 and $30. Artificial Analysis said the model improved by five points from Grok 4.5 in a little more than a month and by 23 points from Grok 4.3, with particular strength in agentic work. Gene Munster of Deepwater Asset Management said Grok 4.6 moved from eighth to fourth on the Artificial Analysis leaderboard and argued planned Grok 4.7 and 5.0 releases could push xAI to the top by January, with Grok 4.7 potentially incorporating Cursor data to improve coding and agentic capabilities. Polymarket’s year-end odds for xAI rose to 9% from about 3%, though that market resolves using Arena’s leaderboard rather than Artificial Analysis. Morgan Stanley separately said investors may be undervaluing SpaceX’s AI business and that broader traction through Cursor could help support its $600 bull case for SpaceX shares.
