Reduce AI API costs without losing useful results

Measure workload, retries and accepted outputs before comparing models, batching or reusable prompts.

Direct answer

The decision in brief

Start with cost per accepted result, not the advertised token price. Measure every billed attempt, remove accidental retries and oversized context, then test model changes, batching and prompt caching against the same workload and acceptance rule.

What should you change first?

  1. Measure one representative period: tasks, billed input and output tokens, elapsed time, failures and results that pass your acceptance rule.
  2. Fix accidental retries and oversized context before changing providers. Failed charged attempts belong in the total cost.
  3. Compare models with the same task set and acceptance rule. Use cost per successful task rather than token price alone.
  4. Choose batching when work can wait; test prompt caching only when an eligible prefix actually repeats. Record cache writes, reads and misses separately.

Use these as evaluation steps for your own workload. Record the evidence and limits before acting on the result.

Evidence and next steps

Review the evidence

Measure AI API retry cost before changing models

Count failed attempts, final successful tasks and token use separately so retries do not hide the real cost of useful API work.

Next step

How retries change AI API cost per successful task

A reproducible scenario analysis separates token spend, average attempts and final successful tasks across four retry assumptions.
