AI costs grow quietly. Most of the bill comes from tokens, the small pieces of text you send in and get back. The good news: a few habits usually cut spending without hurting quality. Work through these in order.

1. Measure before you change anything

Log tokens in and out for each request, by feature. You cannot save what you cannot see, and most waste hides in one or two places.

2. Match the model to the task

Simple jobs such as classification, formatting or short answers rarely need your largest model. Route easy tasks to a smaller, cheaper model and keep the big one for hard work.

3. Trim your prompts

Remove repeated boilerplate, long examples you no longer need and politeness filler. Shorter, clearer instructions often work just as well.

4. Cache repeated context

If you send the same long instructions or documents again and again, check whether your provider offers prompt caching. Repeated input is usually billed at a lower rate.

5. Limit the output

Set a sensible maximum output length and ask for concise or structured answers. Output tokens often cost more than input tokens.

6. Summarise long conversations

Instead of resending an entire chat history every turn, keep a short running summary plus the last few messages.

7. Batch work that can wait

Many providers offer cheaper batch processing for non-urgent jobs such as bulk summaries or tagging. Check your provider's current terms.

8. Retrieve only what you need

When using documents, send the few relevant passages rather than the whole file. Better retrieval means fewer tokens and often better answers.

Set a budget and an alert

Add a monthly limit and an alert at about 80%. Surprises are the most expensive kind of AI cost.

Prices and features differ by provider and change often. Always check the provider's official pricing page before making decisions.
