Why high: an exact fingerprint shared with 8 models.
MiniMax: MiniMax-01 is MiniMax's model, and its measured tokenizer sits in MiniMax's own signature group alongside its sibling models. Measured models from Undisclosed (stealth) carry the same vocabulary, which reads as reuse of MiniMax's tokenizer line and questions nobody's authorship; they are listed under "Shares this fingerprint" below.

We sent MiniMax: MiniMax-01 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.
Overhead subtracted: 711 prompt tokens.
MiniMax-01 is a combines MiniMax-Text-01 for text generation and MiniMax-VL-01 for image understanding. It has 456 billion parameters, with 45.9 billion parameters activated per inference, and can handle a context...
