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
Command A+ costs less
Repository review
50K input + 3K output tokens
Command A+ costs less
Agent loop
200K input + 10K output tokens
Command A+ costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
