It does not reproducibly identify itself as Claude, there's evidence to the contrary in the very thread you linked: https://x.com/bobbyNewcomb5/status/207815156

As mentioned in my comment, Kimi K3 identifies itself as Claude ~15% of the time. Here's another report of K3 identifying itself as Claude https://x.com/Sauers_/status/2077842686459981901 https://x.com/Sauers_/status/2077842686459981901 And an analysis showing the self-identity distribution for K3 and other models https://x.com/RyanGreenblatt/status/2078663148509544589 https://x.com/RyanGreenblatt/status/2078663148509544589

  Your main source is Ryan Greenblatt who is a regular recipient of community notes and has no corroboration for the 15% statistic other than his assertion. The other tweet (Sauers_) is also community noted as engagement farming with a false system prompt, so forgive me for being skeptical.

    Including the three sources above, multiple others have reported that K3 self-identifies as Claude. "I'm actually Claude - not Kimi". https://x.com/PimDeWitte/status/2077884701470040083 https://x.com/PimDeWitte/status/2077884701470040083 I regret to inform you that it is, in fact, real and from their own website - you don’t even need to try hard to reproduce it. https://x.com/PimDeWitte/status/2078105292965912690 https://x.com/PimDeWitte/status/2078105292965912690 lmao this is so funny, if you ask Kimi K3 for something with an empty system prompt it will consistently think of itself as Claude https://x.com/__alula/status/2078359305741275445 https://x.com/__alula/status/2078359305741275445 "I genuinely believe I'm Claude based on everything in my training" https://x.com/williawa/status/2077869021589033002 https://x.com/williawa/status/2077869021589033002 another "I'm actually Claude - not Kimi", including the system prompt https://x.com/jchudnov/status/2078661564803207406/photo/1 https://x.com/jchudnov/status/2078661564803207406/photo/1

      my first prompt to any Kimi model was K3 via Pi, some version of "hi kimi!!" and the response was telling me "I'm actually Claude." this is not hard to repro, just use a system prompt that doesn't mention the model name. that said, if they bootstrapped with opus 4.6 convo sft data they had sitting around... so what?

        The main story is what isn't being talked about. Chinese labs exfiltrated trillions of tokens of high-quality output from Anthropic and OpenAI, through proxies and heavily discounted token resellers, which they distilled and used for training data for their own models. Instead of spending 12-18 months building their own robust harnesses and painstakingly creating quality training data (which is what Anthropic and OpenAI did), they distilled Anthropic's models to bypass the hardest parts of development. Chinese labs compressed 18 months of intensive research and development into just 6 months, and are now head-to-head with their American counterparts. Anthropic tried to complain about this unauthorized "token theft", but they burned too much public goodwill with BS safety restrictions and users don't care. The US government is too busy fighting a war to help. Chinese labs are offering highly capable, cheap, open-weight models; exactly what users want. The community is happy to overlook any questionable methods Chinese labs used to build them. The cope is incredible. There's people in this thread in denial that Moonshot AI is trained on exfiltrated Anthropic's model output, even when shown substantial evidence this has been happening since Kimi 2.X Chinese labs were even paying an absurd $0.01 per Opus tool call trace, to get the quantity of training data needed. Kimi K3 has reached the point of RSI, and no longer needs synthetic data generated by Anthropic/OpenAI models. K3 is now capable enough to generate, iterate, and improve its own training data recursively. The data exfiltration is complete. We witnessed the most extensive industrial espionage campaign, probably ever, and nobody in the industry cares at all that it happened.

        assuming the k3 model weights do indeed get published, if your model of the world is "achieving RSI is beneficial and K3 has done so," this feels structurally different from ordinary industrial espionage, because the knowledge has enriched the commons more like silk than capacitors if, again, your model is that RSI will be beneficial, why wouldn't making it available to all unlock more benefit globally than not doing that
