GLM 4.7 vs GPT-4o-mini
GLM 4.7 leads GPT-4o-mini on the Artificial Analysis Intelligence Index, 22.2 to 6.7, and GPT-4o-mini costs 3.7x less per output token ($0.60 vs $2.20 per million). Updated October 21, 2026; 18 benchmarks have a result for both.
GLM 4.7 or GPT-4o-mini: which to pick
Only GLM 4.7 has a coding score, 55.1 on the Vibe Coding Index; GPT-4o-mini has none, so the two cannot be ranked on coding.
Pick GPT-4o-mini for output tokens 3.7x cheaper ($0.60 vs $2.20 per million).

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
GPT-4o-mini costs less
Repository review
50K input + 3K output tokens
GPT-4o-mini costs less
Agent loop

GPT-4o-mini 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 4.7 better than GPT-4o-mini for coding?
Only GLM 4.7 has a coding score, 55.1 on the Vibe Coding Index; GPT-4o-mini has none, so the two cannot be ranked on coding. Pick GPT-4o-mini for output tokens 3.7x cheaper ($0.60 vs $2.20 per million).
Which is cheaper, GLM 4.7 or GPT-4o-mini?
GLM 4.7 costs $0.60 per million input tokens and $2.20 per million output tokens; GPT-4o-mini costs $0.15 and $0.60. Cost per solved task is known for GLM 4.7 only.
Which has the bigger context window, GLM 4.7 or GPT-4o-mini?
GLM 4.7, with 205K tokens against 128K.
How many benchmarks is the GLM 4.7 vs GPT-4o-mini comparison based on?
18 benchmarks have a result for both models as of October 21, 2026. GLM 4.7's coding index rests on 2 independent benchmarks and GPT-4o-mini's on 0. Where only one model has a result, the page says so instead of naming a winner.
