China’s Moonshot to release breakthrough Kimi K3 AI model for download

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 artificial intelligence development.

The Beijing-based company is due on Monday (Jul 27) to release the model’s weights, which are used to steer AI systems towards 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 sell-off in AI-related stocks in July, as it demonstrated Chinese-made models are closing the gap with American leaders OpenAI and Anthropic.

Much like DeepSeek’s release in January 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 AI accelerators.

Monday’s release may boost business for cloud AI computing providers who specialise 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 US$50 billion valuation ahead of a potential Hong Kong initial public offering as soon as this year.

Bloomberg Intelligence analysts Mandeep Singh and William Tong said: “Open-weight large language model adoption is inflecting, but monetisation 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 per cent after the launch of Moonshot AI’s Kimi K3 and Z.AI’s GLM-5.2,” the analysts said.

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.

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 one-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. BLOOMBERG
