Rate Limits & Cost Management

Summary

LLM APIs charge per token and enforce request-rate limits — production AI features need deliberate cost tracking and backoff/retry logic to avoid surprise bills or failures.

• 1Add token-usage logging and a rough cost estimate to every API call in a project.
• 2Implement exponential backoff and retry logic for rate-limit errors.
• 3Learn techniques (caching, smaller models for simple tasks) to control cost at scale.
