Greptile Overview

Greptile Summary

This PR introduces a tiered pricing system for LLM models to support usage-based pricing variations. The changes add new TypeScript types for pricing tiers with conditional matching based on usage patterns (e.g., different rates for high-volume usage or large context windows).

Key changes:

• Added PricingTier, PricingTierCondition, PricingTierInput, and PricingTierOperator types
• Extended Model interface with pricingTiers array and createdAt timestamp
• Deprecated flat pricing fields (inputPrice, outputPrice, totalPrice) in favor of tiered pricing
• Maintained backward compatibility by populating legacy price fields from the default tier
• Updated CreateModelRequest to accept either flat prices or pricing tiers (mutually exclusive)

The implementation is well-documented with comprehensive JSDoc comments explaining tier matching logic, priority ordering, and usage examples. All files are auto-generated from the API specification, ensuring consistency with the backend.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk as it consists of auto-generated TypeScript type definitions
• The changes are auto-generated from the API specification, adding new types without modifying existing logic. The implementation maintains backward compatibility through deprecated fields and includes comprehensive documentation. No runtime code changes or complex logic alterations are present.
• No files require special attention
