Operational costs
Cheaper per token is not always cheaper per task
Retries, failed calls, fallback requests, and longer outputs can raise the cost of completing a task even when the published token price is lower. Model the effect with the LLM Retry & Fallback Cost Calculator, read the cost-per-successful-task guide, or estimate a migration with the Model Switch Cost Calculator.
