China's high-performance AI 'Kimi-K3' will be released as an open model as planned, boasting 2.8 trillion parameters and performance approaching that of Claude Fable 5 and GPT-5.6 Sol.

Chinese company Moonshot AI has released its proprietary AI model, ' Kimi K3, ' as an open model.

Kimi K3 is a model announced on July 17, 2026 (Japan time), with 2.8 trillion parameters and a context window of 1 million tokens. It has achieved scores that surpass cutting-edge models such as Claude Fable 5 and GPT-5.6 Sol in multiple benchmark tests, and is attracting attention as a cost-effective, high-performance model.

Immediately after its announcement, Kimi K3 became available for use through the chat AI 'Kimi.com' and via API, and it was declared that 'the entire model and technical report would be released on July 27, 2026.' The model was then released on July 27, 2026 UTC (around 0:00 on July 28, 2026 Japan time) at the following link. The license used is the ' Kimi K3 License .'

Kimi-K3 is an enormous model with 2.8 trillion parameters, requiring several terabytes of memory to run. Therefore, its primary use is not 'download and run on your own PC,' but rather 'run on a third-party cloud.' LM Studio has already started hosting Kimi-K3 on servers in the United States, and Kimi-K3 is available through the agent AI application ' LM Studio Bionic .'

Additionally, Kimi K3 can be used with Ollama's cloud service.

To use it with Claude Code, run:

ollama launch claude --model kimi-k3:cloud

Currently Kimi K3 requires a Pro or Max subscription, and consumes extra usage credits. We're quickly working on adding capacity to expand access. https://t.co/CYHwTjpy1H

The Kimi K3 has been popular since its release, and Moonshot AI's servers were unable to meet the demand, leading to a temporary suspension of new subscriptions. With the release of this model, it will now be hosted on third-party servers, making the Kimi K3 more accessible to some users.

Kimi K3, a Chinese AI with performance comparable to Claude Fable 5, has become so popular that it has run out of GPUs, forcing a temporary suspension of new subscriptions. Some are saying this is 'better than Anthropic's response' - GIGAZINE
