Moderate

Why moderate: an exact fingerprint match with one sibling only, and no second signal of a different kind yet.

Evidence
  • ✓ exact tokenizer signature shared with 1 model

Identity statement

Cohere: Command R7B (12-2024) is Cohere's model, and its measured tokenizer sits in Cohere's own signature group alongside its sibling models. No other maker's measured model shares it so far.

The measured fingerprint

What each test string cost this model, in tokens

We sent Cohere: Command R7B (12-2024) 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.
