What are tokens?
Tokens are the basic units AI models use to process text. A token can be a word, part of a word, or punctuation. On average, one English word equals about 1.3 tokens. Token count affects both API costs and context window limits.
Why token count matters
- Cost control: API pricing is per-token. Knowing your token count helps estimate costs before sending requests.
- Context limits: Each model has a maximum context window. Long prompts may need trimming to fit.
- Prompt optimization: Shorter prompts that achieve the same result save money and reduce latency.
