Command A vs GLM 4.5 Air
Command A leads GLM 4.5 Air on the Artificial Analysis Intelligence Index, 13.1 to 11.1, and GLM 4.5 Air costs 9.1x less per output token ($1.10 vs $10.00 per million). Updated October 21, 2026; 40 benchmarks have a result for both.
Command A or GLM 4.5 Air: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Command A for a larger context window (256K against 131K tokens) and work measured by LiveCodeBench (Artificial Analysis run) or LMArena Text: coding, where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
GLM 4.5 Air costs less

Questions
Is Command A better than GLM 4.5 Air for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick Command A for a larger context window (256K against 131K tokens) and work measured by LiveCodeBench (Artificial Analysis run) or LMArena Text: coding, where it leads.
Which is cheaper, Command A or GLM 4.5 Air?
Command A costs $2.50 per million input tokens and $10.00 per million output tokens; GLM 4.5 Air costs $0.20 and $1.10. Cost per solved task is known for Command A only.
Which has the bigger context window, Command A or GLM 4.5 Air?
Command A, with 256K tokens against 131K.
How many benchmarks is the Command A vs GLM 4.5 Air comparison based on?
40 benchmarks have a result for both models as of October 21, 2026. Command A's coding index rests on 1 independent benchmark and GLM 4.5 Air's on 0. Where only one model has a result, the page says so instead of naming a winner.
