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
Phi 4 costs less
Repository review

Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
