AI Tokenizer Differences: Why Token Counts Vary Across Models
The premise
AI model tokenizers (BPE, SentencePiece, tiktoken variants) tokenize the same text into different counts — affecting cost, context fit, and multilingual fairness.
What AI does well here
Counting tokens accurately for its native tokenizer when given a tool
Handling its tokenizer's particular merges and splits
Producing reasonable output across modeled scripts
Performing better on languages well-represented in tokenizer training
What AI cannot do
Convert token counts between providers without per-tokenizer libraries
Tokenize fairly across all scripts and languages
