Moonshot AI is set to release its Kimi K3 model for public download, enabling developers to modify and host the technology. This move aims to improve accessibility and compete against established US AI companies. The launch is significant as K3, with 2.8 trillion parameters, is the largest open-weight model and can handle extensive documents due to its 1-million-token context window. This development follows a surge in demand for Chinese-made AI models, prompting a sixfold increase in Moonshot's sales. However, concerns have been raised regarding potential use of banned Nvidia chips and competitive practices. The company is also pursuing a $50 billion valuation ahead of a possible IPO.

China’s Moonshot to Release Breakthrough AI Model for Download

(Bloomberg) -- Moonshot AI is poised to make its Kimi K3 model available for public download, expanding its reach and influence in the global open software community at a time of growing US concern about Chinese encroachment into the top echelons of AI development.

The Beijing-based company is due on Monday to release the model's weights, which are used to steer artificial intelligence systems toward answers. That will enable developers to download, tweak and host the technology freely in a move to broaden the user base of Moonshot's AI. Founder Yang Zhilin has said he wants to win users by focusing on openness and greater availability than competing US proprietary systems.

Kimi K3's initial announcement and benchmark performance triggered a selloff in AI-related stocks this month, as it demonstrated Chinese-made models are closing the gap on American leaders OpenAI and Anthropic PBC. Much like DeepSeek's release in early 2025, the K3 debut was taken as evidence that Chinese companies can keep pace on a smaller budget and with fewer cutting-edge resources than rivals with full access to Nvidia Corp. AI accelerators.

Monday's release may boost business for cloud AI computing providers who specialize in hosting third-party open models. Made-in-China AI models have surged in global popularity in recent times, led by DeepSeek, as they offer more affordable rates and comparable performance to US offerings.

Daily sales at Moonshot have surged at least sixfold since K3's debut, Bloomberg News has reported. The Beijing-based startup is riding that momentum as it seeks a new funding round at a $50 billion valuation ahead of a potential Hong Kong initial public offering as soon as this year.

What Bloomberg Intelligence Says

Open-weight large language model adoption is inflecting, but monetization will hinge on distribution through hyperscale cloud providers. Amazon AWS Bedrock, Microsoft Azure Foundry and Google Vertex AI have yet to support these open-weight Chinese models, even as their token-volume mix reached 68% after the launch of Moonshot AI's Kimi K3 and Z.AI's GLM-5.2.

Moonshot's success has thrust it into the US-China tech crosshairs. A White House official last week accused the company of training K3 on banned Nvidia chips, while reviving allegations of distillation — the practice of illicitly extracting outputs from top competitor models to boost its own performance. Moonshot has not responded to requests for comment on the matter.

Story Continues

Moonshot developed K3 with 2.8 trillion parameters — a rough measure of AI complexity — making it the world's largest open-weight model at a time when leading rivals like Anthropic are keeping the size of models like Claude private. K3 also features a 1-million-token context window, enabling it to process massive documents or codebases in a single prompt. While raw model weights offer little human-readable insight on their own, Moonshot is set to reveal further details on its architecture, training, and evaluation benchmarks in an upcoming technical report.
