This is a character/word-based approximation, not the real tokenizer each provider uses internally — expect it to land within roughly 10–15% of the actual count for plain English text. For an exact count against Claude's own tokenizer, use the Messages API's
count_tokens endpoint.0 tokens

Counting Gemini tokens
For an exact count, call the Gemini API's countTokens method with your model, or read usageMetadata from a response.
- →Google's rule of thumb is about 4 characters per token for Gemini models.
- →Gemini 3.1 Pro charges higher rates for prompts over 200K tokens, for the whole request.
- →Some Gemini prices have announced increases (Gemini 4 Argon from 1 December 2026, Gemini 3.8 Flash from 1 January 2027); the cost column switches automatically on those dates.
Frequently asked
How do I count Gemini tokens exactly?
Use the countTokens method of the Gemini API (or the SDK's count_tokens) with the model you'll call. It returns the token count without generating anything.
Do thinking tokens count for Gemini?
Yes. Gemini bills thinking tokens at the output price, which Google's pricing page notes as "output price (including thinking tokens)".
