GLM 4.6 vs Hy3
Hy3 costs 4.2x less per output token than GLM 4.6 ($0.528 vs $2.20 per million). Updated October 22, 2026; 41 benchmarks have a result for both.
GLM 4.6 or Hy3: which to pick
Only GLM 4.6 has a coding score, 8.8 on the Vibe Coding Index; Hy3 has none, so the two cannot be ranked on coding.
Pick Hy3 for output tokens 4.2x cheaper ($0.528 vs $2.20 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.
