Walkthrough

The change modifies the fallback pricing logic in ModelPriceHelperPerCall function, replacing a hard-coded price value of 0.1 with a computed calculation based on PreConsumedQuota and QuotaPerUnit constants. This affects how model prices are determined when no explicit price configuration exists.

🐰 A price so fixed at point-one bright,
Now dances with quotas, a dynamic sight,
PreConsumed wisdom guides the way,
Fairer pricing starts today! ✨
