## Summary

A study by the Coalition for Language Equity in AI Research found AI models need far more tokens for some languages than others. Among the 20 most popular internet languages, the most expensive used 1.5 to 5 times more tokens than the cheapest, a gap that grew 17 times across 200 languages in one model. The researchers call this a "tokenizer tax," which raises costs and latency and reduces effective context capacity.
