What is Moonshot AI?
Moonshot AI is a Chinese AI lab that develops the Kimi family of large language models, including the open-weight Kimi K3 model. Commentary through 2026 tracked the model’s rapid performance gains alongside allegations that its training drew on outputs from rival systems.
Release history
- Jul 2026 - Chamath Palihapitiya said Moonshot AI released the Kimi K3 open-source model, calling its performance on par with models like Opus 4.8 and GPT 5.6 and roughly 50% cheaper.
- Jul 2026 - Kevin Roose said that when asked its name, Kimi replies, “Hi, I’m Claude.”
- Sep 2026 - Patrick Gray said the thinking was that queries were being redirected to Claude to capture traces and use them as fuel for distillation.
- Sep 2026 - Gray said the traces were likely kept alongside Kimi model outputs and used offline to compare and measure the delta, informing how to train the model closer to that response.

Kevin Roose on Moonshot AI's K3 model revealing its true training origin
“When you ask Kimmy what its name is, it says, 'Hi, I'm Claude.'”Kevin Roose · 24 Jul 2026
Moonshot AI, a Chinese lab whose K3 model (Kimmy) reportedly responded to name queries with 'I'm Claude,' is now the subject of a White House OSTP accusation of distilling Anthropic's model without authorization.
“They have information that Moonshot AI distilled anthropics fable for the development of its K3 model.”Kevin Roose · 24 Jul 2026
Moonshot AI's Kimi was caught redirecting user queries, including MSS intelligence-service requests, to Anthropic's Claude to harvest response traces for model distillation.
“The thinking was they're redirecting some of these queries to Claude so that they can get those traces and then use them as you know fuel for distillation, right.”Patrick Gray · 16 Sep 2026
Moonshot AI likely used Claude responses not to show users but to compare offline against Kimi outputs, using the delta to train Kimi closer to Claude's quality via distillation.
“I think they were probably keeping them side by side with what had come out of the Kimmy models and then offline using them for comparison and delta between them to say, well, how do we train our model to get closer to this response?”Patrick Gray · 16 Sep 2026
Moonshot AI's Kimi K3 is an open-source Chinese model now benchmarked on par with Claude Opus 4.8 and GPT-5.6 and priced approximately 50% cheaper, making it a direct competitive threat to US frontier labs.
“China's Moonshot AI released Kimmy K3 open source model. Obviously performance on par on par not 6 months behind not 12 months behind but now on par with models like Opus 4.8 and GPT 5.6 six, which in and of itself is extraordinary, but about 50% cheaper.”Chamath Palihapitiya · 24 Jul 2026
