Definition
Pay as you go is a commercial or pricing concept in the AI market. It is part of the vocabulary teams use when they compare models, design prompts or review an AI system. The term is used in business and pricing discussions, where precision matters: two teams can use the same word to mean slightly different things. In this glossary, pay as you go is treated as a practical concept rather than a formal specification.
Why it matters
Business terms describe how AI models are packaged, priced and procured. They matter because token pricing, caching and volume discounts can change the economics of a product more than a few benchmark points.
Example
Suppose you are comparing Yi-Lightning with another model for a production task. Pay as you go is one of the factors behind the numbers you see: Yi-Lightning lists a 32,768-token context window, costs $4.22 per million input tokens and scores 80.1 on MATH-500. Understanding the term helps you decide which of those differences actually matter for your workload.
How to evaluate it
- Check whether pay as you go is defined the same way in the documentation you are reading.
- Ask which measurement or trade-off the term is describing before comparing numbers.
- Separate vendor claims from independently observed behaviour on your own data.
- Write down the definition your team uses so reviews and evaluations stay consistent.
