Grok 4.3 vs Llama 4 Maverick
Grok 4.3 leads Llama 4 Maverick on the Artificial Analysis Intelligence Index, 24.9 to 9.3, and Llama 4 Maverick costs 2.5x less per output token ($1.00 vs $2.50 per million). Updated October 21, 2026; 67 benchmarks have a result for both.
Grok 4.3 or Llama 4 Maverick: which to pick
Only Grok 4.3 has a coding score, 37.4 on the Vibe Coding Index; Llama 4 Maverick has none, so the two cannot be ranked on coding.
Pick Llama 4 Maverick for output tokens 2.5x cheaper ($1.00 vs $2.50 per million) and work measured by MortgageTax (Vals AI) or SAGE (Vals AI), where it leads.
