GPT-4.1 vs Grok 4.6
Grok 4.6 leads GPT-4.1 on the Artificial Analysis Intelligence Index, 44.3 to 12.7, and Grok 4.6 costs 1.3x less per output token ($6.00 vs $8.00 per million). Updated October 22, 2026; 66 benchmarks have a result for both.
GPT-4.1 or Grok 4.6: which to pick
Only Grok 4.6 has a coding score, 65.7 on the Vibe Coding Index; GPT-4.1 has none, so the two cannot be ranked on coding.
Pick GPT-4.1 for a lower cost per solved task ($0.37 against $0.82) and a larger context window (1.05M against 500K tokens).
