Same workload as the calculator above, at each model's current price. Monthly USD.
Routed-token share over time. A price line joins it as real changes are recorded.
Low cost · adoption flat. Observed relationship, not proof of causation.
Availability monitoring is derived from OpenRouter provider uptime; it refreshes with the daily build. Latency and throughput are not exposed by the data source, so we do not report them rather than estimate.
