GLM 5 vs Hy3
Hy3 costs 6.1x less per output token than GLM 5 ($0.528 vs $3.20 per million). Updated October 22, 2026; 43 benchmarks have a result for both.
GLM 5 or Hy3: which to pick
Only GLM 5 has a coding score, 41.7 on the Vibe Coding Index; Hy3 has none, so the two cannot be ranked on coding.
Pick Hy3 for output tokens 6.1x cheaper ($0.528 vs $3.20 per million) and a larger context window (262K against 205K tokens).

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
Hy3 costs less
Repository review
50K input + 3K output tokens
Hy3 costs less
Agent loop
200K input + 10K output tokens
Hy3 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 5 better than Hy3 for coding?
Only GLM 5 has a coding score, 41.7 on the Vibe Coding Index; Hy3 has none, so the two cannot be ranked on coding. Pick Hy3 for output tokens 6.1x cheaper ($0.528 vs $3.20 per million) and a larger context window (262K against 205K tokens).
Which is cheaper, GLM 5 or Hy3?
GLM 5 costs $1.00 per million input tokens and $3.20 per million output tokens; Hy3 costs $0.132 and $0.528. Cost per solved task is known for GLM 5 only.
Which has the bigger context window, GLM 5 or Hy3?
Hy3, with 262K tokens against 205K.
How many benchmarks is the GLM 5 vs Hy3 comparison based on?
43 benchmarks have a result for both models as of October 22, 2026. GLM 5's coding index rests on 3 independent benchmarks and Hy3's on 1. Where only one model has a result, the page says so instead of naming a winner.
