GLM 5V Turbo vs o3
GLM 5V Turbo leads o3 on the Artificial Analysis Intelligence Index, 23.5 to 20.2, and GLM 5V Turbo costs 2.0x less per output token ($4.00 vs $8.00 per million). Updated October 22, 2026; 49 benchmarks have a result for both.
GLM 5V Turbo or o3: 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 2.0x cheaper ($4.00 vs $8.00 per million) and a larger context window (203K against 200K tokens).

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 5V Turbo costs less

Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.

Questions
Is GLM 5V Turbo better than o3 for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick GLM 5V Turbo for output tokens 2.0x cheaper ($4.00 vs $8.00 per million) and a larger context window (203K against 200K tokens).
Which is cheaper, GLM 5V Turbo or o3?
GLM 5V Turbo costs $1.20 per million input tokens and $4.00 per million output tokens; o3 costs $2.00 and $8.00. Cost per solved task is known for o3 only.
Which has the bigger context window, GLM 5V Turbo or o3?
GLM 5V Turbo, with 203K tokens against 200K.
How many benchmarks is the GLM 5V Turbo vs o3 comparison based on?
49 benchmarks have a result for both models as of October 22, 2026. GLM 5V Turbo's coding index rests on 1 independent benchmark and o3's on 0. Where only one model has a result, the page says so instead of naming a winner.
