-Extend the `cost.ts` file to support your specific pricing models:
-
-```typescript
-export const MODEL_COSTS: Record<string, CostConfig> = {
-  "gpt-4": { input: 0.03, cached: 0.015, output: 0.06 },
-  "claude-3": { input: 0.025, cached: 0.0125, output: 0.125 },
-  "custom-model": { input: 0.01, cached: 0.005, output: 0.02 },
-};
