Phi-4 uses Tiktoken tokenizer (100k vocab).

2412.08905v1

we now use the tiktoken tokenizer (for better multilingual support) with a padded vocabulary size of 100,352 (including unused tokens)

Consider adding it as an option to the encoding map so it's easier to create.

                Phi-4 uses Tiktoken tokenizer (100k vocab).
                2412.08905v1
                we now use the tiktoken tokenizer (for better multilingual support) with a padded vocabulary size of 100,352 (including unused tokens)
                Consider adding it as an option to the encoding map so it's easier to create.
