Each point is the trailing seven-day token total as of that day, which is what
OpenRouter's model leaderboard publishes — not that day's usage on its own. Sampled hourly by
token.app and stored since 2026-09-22; only the models currently on OpenRouter's board
appear here, so a missing panel means we have no current data, not zero usage.
