Gemini 2.5 Flash wins five of the seven areas where both have results: agents, reasoning, images and charts, long documents and following instructions. GLM-4.6V wins coding, and costs 57% less. They are level on facts.
Which is better for coding?
GLM-4.6V. It wins 1 of the 2 coding tests both models report; Gemini 2.5 Flash wins none, and 1 is a tie.
Which is cheaper?
Gemini 2.5 Flash costs $0.30 per million input tokens and $2.50 per million output tokens; GLM-4.6V costs $0.30 and $0.90. That makes GLM-4.6V about 57% cheaper for the same work.
How do you compare the two?
We use the 17 benchmark tests both models have published scores on. The verdict counts the 12 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 5 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.
