In my first interaction ("hi there kimi k3!"), Kimi K3 identified twice out of three times as Claude:
> Hi there! Quick note — I'm actually Claude, made by Anthropic, not Kimi. But no worries!
and
> Just a quick heads-up — I'm Claude, made by Anthropic, not Kimi! Kimi is a different AI assistant (made by Moonshot AI), so it looks like there might be a little mix-up.
Models don't have an inherent identity. It should be obvious by now that every models trains on public AI chat session transcripts. I've seen Claude say it's Qwen.
This happens with other models too - Gemini often identifies as ChatGPT for me, confusing many a debugging attempt
