R1 0528 vs GPT-4
R1 0528 leads GPT-4 on the Artificial Analysis Intelligence Index, 13.1 to 6.7, and R1 0528 costs 27.5x less per output token ($2.18 vs $60.00 per million). Updated October 22, 2026; 32 benchmarks have a result for both.
R1 0528 or GPT-4: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick R1 0528 for output tokens 27.5x cheaper ($2.18 vs $60.00 per million) and a larger context window (164K against 8K tokens).
