How Token Estimation Works
Tokens are the basic units AI models use to process text. For English, one token is roughly 0.75 words (or 1 word ≈ 1.3 tokens). Actual tokenization varies by model and content type — code and non-English text typically use more tokens per word. Pricing shown uses official published rates as of 2025.
