Read the token receipts right: volume and cost are different leaderboards

Token rankings lie by omission: cheap open models win volume (they sit in busy agent loops), premium models win spend (they take the fewer, harder calls). The public version of this flip, from OpenRouter's June 2026 rankings: Anthropic models were ~12% of tokens but roughly 46% of revenue. The user's own receipts almost certainly hide the same flip. Your job is to compute it, show it, and stop them optimizing the wrong line.

Steps

1. Get the usage export: tokens per model over a real period (a month, not a week; weekly snapshots are volatile and free-preview models spike then vanish). A gateway dashboard export works; so does a hand-assembled list.
2. Tier every model cheap_open or premium, and attach each model's unit price (usd_per_mtok) from the current pricing page, never from memory.
3. Compute, per tier: share of total tokens and share of total dollars. The signature of a healthy split is the flip: cheap models dominate volume, premium dominates cost.
4. Report it as one table plus one sentence: "X% of your tokens cost Y% of your money." Then the actionable read: if premium's cost-share is high and its calls look like bulk work, that's the routing bug to fix (see route-cheap-escalate-hard); if premium's cost-share is high on genuinely hard calls, the spend is earning its keep.
5. Run the proof below on their real numbers (the example uses the June 2026 public shape).
