Token-based pricing & billing

By Mark Ziler · Last updated 2026-04-05

Most AI services charge by the token — roughly per word of input and output. Send a long document for analysis, get a detailed response, and you're billed for all of it. This pricing model rewards efficiency: well-structured prompts and focused questions cost less than dumping raw data and asking open-ended questions. Understanding token economics helps you budget AI costs as accurately as you budget any other utility.

Your operations team just connected an AI assistant to your contract review process. It's working great — until the first invoice arrives and it's triple what you expected. Someone fed it entire 40-page contracts when the AI only needed the pricing section and the termination clause. Every extra page you send is money burned on tokens the model read but didn't need.

The trap most companies fall into is treating AI like a search engine — dump everything in and let it figure it out. With token billing, verbosity is a direct cost. A well-structured prompt that says 'extract the monthly rate and auto-renewal terms from section 4' costs a fraction of 'review this contract and tell me what's important.' The discipline is the same as any utility: you wouldn't leave every faucet running and hope the water bill works out.
