Gemini 4 Argon vs GLM 4.5
Gemini 4 Argon leads GLM 4.5 on the Artificial Analysis Intelligence Index, 52.6 to 12.8, and GLM 4.5 costs 4.5x less per output token ($2.20 vs $10.00 per million). Updated October 21, 2026; 34 benchmarks have a result for both.
Gemini 4 Argon or GLM 4.5: which to pick
Only Gemini 4 Argon has a coding score, 81.0 on the Vibe Coding Index; GLM 4.5 has none, so the two cannot be ranked on coding.
Pick GLM 4.5 for output tokens 4.5x cheaper ($2.20 vs $10.00 per million).
