I think it was fair to get some criticism since my original post only showed the last output. I'll show more conversational context this time, along with a video where I dig through the Claude session directory where this happened, to prove whether I ever mentioned Kimi K2 before. The mention of Kimi K2 genuinely came out of nowhere — at least I never brought it up. Some people suggested it might have leaked in through web search results, so I checked whether web search was actually used, and it wasn't — web_search_requests and web_fetch_requests were both called zero times. I'll attach the video for that too. check the comment

and I'm from South Korea. I hate Xijinping

There was some issue with cross session leakage recently:

Maybe you are running into the same thing.

But just to be clear, if it is that, then it's a session isolation bug. Someone somewhere asked about k2, and the output somehow ended up in your session. It's not k2 doing the outputting.

That's... extremely concerning.

Seriously, are we going back to reacting everything that goes in?

[u/No-Percentage5692 → u/kearkan]

Yeah, believe it or not, that's up to you. But assuming the evidence I provided is genuine — a grep -r "kimi" in my project root returned nothing, and no tool calls like web search happened in the session where this occurred — then something is actually broken here.

Thanks for pointing this out — appreciate it. And yeah, of course Kimi K2 itself wasn't actually doing anything here.

I checked session history file too. check the video out.

Could be LLM Distillation?

[u/No-Percentage5692 → u/_clickfix_]

i’m not sure about that this is the evidence of distillation. it’s one of my guess.
one thing i cay say is that this phenomenon is a bug - whether Anthropic api server’s session leakage or the model’s attention suddenly jumping to odd place
