The measured fingerprint

What each test string cost this model, in tokens

We sent Amazon: Nova Premier 1.0 fifty short pieces of text and recorded what each one cost it in tokens. The bars below are those costs. Two models built on the same tokenizer produce the same bars; a model built on a different one produces a different set, which is what makes this a fingerprint.
