GLM 5V Turbo vs GPT-4 Turbo
GLM 5V Turbo leads GPT-4 Turbo on the Artificial Analysis Intelligence Index, 23.5 to 7.0, and GLM 5V Turbo costs 7.5x less per output token ($4.00 vs $30.00 per million). Updated October 22, 2026; 32 benchmarks have a result for both.
GLM 5V Turbo or GPT-4 Turbo: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GLM 5V Turbo for output tokens 7.5x cheaper ($4.00 vs $30.00 per million) and a larger context window (203K against 128K tokens).
