Heat Map Reveals Kimi's Striking Similarity to Claude in LLM Writing

Writing fingerprint analysis of responses reveals Kimi's similarity to Claude

I built a heat map using only words to see which large language models write alike. By analyzing character trigrams and word patterns, I found that Kimi shares a surprising linguistic fingerprint with Claude. This visual approach highlights subtle affinities between models that standard benchmarks often miss, revealing how distinct their voices truly are.
