GPT-4 vs Grok Build 0.1
Grok Build 0.1 leads GPT-4 on the Artificial Analysis Intelligence Index, 27.2 to 6.7, and Grok Build 0.1 costs 30.0x less per output token ($2.00 vs $60.00 per million). Updated October 21, 2026; 2 benchmarks have a result for both.
GPT-4 or Grok Build 0.1: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4 for work measured by AA Coding Index or AA Intelligence Index, where it leads.
