GLM 4.7 vs o3
GLM 4.7 leads o3 on the Artificial Analysis Intelligence Index, 22.2 to 20.2, and GLM 4.7 costs 3.6x less per output token ($2.20 vs $8.00 per million). Updated October 22, 2026; 64 benchmarks have a result for both.
GLM 4.7 or o3: which to pick
Only GLM 4.7 has a coding score, 55.1 on the Vibe Coding Index; o3 has none, so the two cannot be ranked on coding.
Pick o3 for work measured by LiveCodeBench (Vals AI) or Terminal-Bench Hard (Artificial Analysis run), where it leads.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.

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 4.7 better than o3 for coding?
Only GLM 4.7 has a coding score, 55.1 on the Vibe Coding Index; o3 has none, so the two cannot be ranked on coding. Pick o3 for work measured by LiveCodeBench (Vals AI) or Terminal-Bench Hard (Artificial Analysis run), where it leads.
Which is cheaper, GLM 4.7 or o3?
GLM 4.7 costs $0.60 per million input tokens and $2.20 per million output tokens; o3 costs $2.00 and $8.00. Per solved SWE-bench Verified task, GLM 4.7 costs $0.29 and o3 $0.571.
Which has the bigger context window, GLM 4.7 or o3?
GLM 4.7, with 205K tokens against 200K.
How many benchmarks is the GLM 4.7 vs o3 comparison based on?
64 benchmarks have a result for both models as of October 22, 2026. GLM 4.7's coding index rests on 2 independent benchmarks and o3's on 0. Where only one model has a result, the page says so instead of naming a winner.
