Currently we're using tiktoken to calculate token count (not changed from original implementation.) It seems it's already providing a good estimation but ideally we should use this. https://github.com/anthropics/anthropic-tokenizer-typescript

Note that the above library is no longer exactly accurate on Claude 3.

This package can be used to count tokens for Anthropic's older models. As of the Claude 3 models, this algorithm is no longer accurate, but can be used as a very rough approximation. We suggest that you rely on usage in the response body wherever possible.
