Tokenizer / tokenizer The
In one sentence
tokenizer converts the original text into a Token sequence that can be processed by the model, and restores the output Token into readable content.
Why it matters
word segmentation rules affect context occupancy and call costs. Cross-model comparisons must unify tasks rather than mechanically compare the number of Tokens.
Practical considerations
uses a vendor-specified version of the tokenizer, retaining the overhead of role templates, system prompts, and special tags.
FAQ
Why are the Token numbers of the same piece of text different?
Different vocabulary lists, algorithms and dialogue templates will lead to different splitting results.
