AI Token Estimator

How AI token estimation works

Paste the actual text you intend to send, select a model and review the tokenizer status before relying on the token count.

What to expect

Input counts depend on model encoding. Output tokens cannot be known from the prompt alone and are only estimated when you provide an expected output. Model prices should be verified with the provider.

Does the calculator predict AI responses?

No. It estimates input tokens from supplied text and only includes output costs when you enter expected output tokens or actual response data.
