GLM 4.5V vs GLM 5 Turbo
GLM 5 Turbo leads GLM 4.5V on the Artificial Analysis Intelligence Index, 26.6 to 7.6, and GLM 4.5V costs 2.2x less per output token ($1.80 vs $4.00 per million). Updated October 21, 2026; 7 benchmarks have a result for both.
GLM 4.5V or GLM 5 Turbo: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GLM 4.5V for output tokens 2.2x cheaper ($1.80 vs $4.00 per million) and work measured by Terminal-Bench Hard (Artificial Analysis run) or AA Intelligence Index, where it leads.
