Practical names are one token on every loaded vocabulary. Bare names are the cheap shape.
Practical names, then punctuation
Leaderboard
A short practical name (ac, go, src) is often 1 token on every loaded tokenizer. Prefixing a slash almost never is universal — /name is the shape that costs you. Golf: create lowercase alnum names, cite them relatively when the harness allows, and pick names that still merge with '/' on your target model (o200k likes /ac, /go, /db, …).
of 1,390
Strings of the form /name are one token on all eight vocabularies. A leading slash is the tax.
of 1,390
/name is still one token on o200k_base. The other vocabularies split most of them.
