Hy4 is the stronger all-rounder.
Scores updated · 17 tests both models report · How we compare
Where each one wins
Tests won in each of the three areas where both have results. Each piece is one test, so a longer bar means more evidence; grey means the two scored within a point of each other.
What it costs
Prices per million tokens, roughly 750,000 words. The bars show the cost of a million tokens read plus a million written.
Hy4 costs 43% less for the same work.
The biggest differences
The tests each model wins by the widest margin, up to three each. Scores are out of 100.

Questions people ask
Which is better, GLM-5.2 or Hy4?
Hy4 wins two of the three areas where both have results: coding and agents. GLM-5.2 wins none. They are level on reasoning.
Which is better for coding?
Hy4. It wins 3 of the 3 coding tests both models report; GLM-5.2 wins none.
Which is cheaper?
GLM-5.2 costs $1.40 per million input tokens and $4.40 per million output tokens; Hy4 costs $0.83 and $2.50. That makes Hy4 about 43% 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 7 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 10 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.
