← attempt: / ensure: — say whether the instruction tolerates failure
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-15 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -15.5 to -15
The result is on the helpful side of this metric's neutral point.
