Mistral: Mistral Small 4 · NVIDIA: Nemotron 3 Nano 30B A3B

Identity similarity: highExact tokenizer agreement · 50/50Exact agreement across every measured string is one strong signal of shared tokenizer lineage. The published settings differ, so the second signal the methodology needs for very high is absent here; the table below shows where they part.
