Questions people ask
Which is better, GLM-5 or GPT-5.4?
GPT-5.4 wins all seven areas where both have results: coding, agents, reasoning, facts, math, long documents and following instructions. GLM-5 wins none, but costs 76% less.
Which is better for coding?
GPT-5.4. It wins 4 of the 4 coding tests both models report; GLM-5 wins none.
Which is cheaper?
GLM-5 costs $1.00 per million input tokens and $3.20 per million output tokens; GPT-5.4 costs $2.50 and $15.00. That makes GLM-5 about 76% cheaper for the same work.
How do you compare the two?
We use the 40 benchmark tests both models have published scores on. The verdict counts the 21 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 19 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
