This AI Trick Can Save You Thousands in API Costs

Most AI apps are wasting money without realizing it.

Every AI prompt has two parts:

The system prompt — instructions, tone, behavior, context.
The user input — dynamic data from the user.

The problem?
Most teams resend the exact same system prompt on every request and pay full price every time.

That’s where prompt caching helps.

Models like ChatGPT, Claude, and Gemini can cache the static system prompt. So after the first request, future requests become much cheaper.

Real example:
Imagine a support chatbot with a long instruction prompt explaining refund policy, tone, escalation rules, and company context. Without caching, you pay for those tokens on every customer message. With caching, the model reuses it and charges a fraction of the cost.

You may not notice it with 10 users.
You will definitely notice it with 100,000.
