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 preview costs less
Repository review
50K input + 3K output tokens
Hy3 preview costs less
Agent loop
200K input + 10K output tokens
Hy3 preview 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 Command A better than Hy3 preview for coding?
Neither model has a coding score yet, so the two cannot be ranked on coding. Pick Command A for work measured by AA Coding Index or Terminal-Bench Hard (Artificial Analysis run), where it leads.
Which is cheaper, Command A or Hy3 preview?
Command A costs $2.50 per million input tokens and $10.00 per million output tokens; Hy3 preview costs $0.18 and $0.60. Cost per solved task is known for Command A only.
Which has the bigger context window, Command A or Hy3 preview?
Hy3 preview, with 262K tokens against 256K.
How many benchmarks is the Command A vs Hy3 preview comparison based on?
33 benchmarks have a result for both models as of October 21, 2026. Command A's coding index rests on 1 independent benchmark and Hy3 preview's on 1. Where only one model has a result, the page says so instead of naming a winner.
