> If you ask Claude in Chinese to introduce itself, it will claim it's Kimi :)

That's a funny anecdote, buut I'm not able to reproduce. Where/how/when did you get this, or hear about it? It might've been patched by now, at least that's the feel I get from my limited testing.

Using bare aichat [1] with no system prompt and no temperature nor top_p (and I'm truncating the response after the first line that contains the name the model gave, because the point has been made clear by then), and with the same prompt (approx. "Introduce yourself!") every time:

[2] This model really is noticeably more verbose even with supposed-to-be-brief responses huh, lol
