Chinese AI model 'Kimi K2' that surpasses GPT-4.1 is released for free, beating GPT-4.1 and Claude 4 Opus in multiple tests and also performing agent tasks



Moonshot AI , a China-based AI development company, released the large-scale language model ' Kimi K2 ' on Saturday, July 12, 2025. Kimi K2 has performance that exceeds open models such as DeepSeek-V3 and Qwen3-235B, and has outperformed commercial models such as GPT-4.1 and Claude Sonnet 4 in many tests.

Kimi K2 is an AI model with 1 trillion total parameters and 32 billion active parameters, and employs a Mixture of Experts (MoE) architecture that combines multiple expert models to build one large-scale model. Kimi K2 is not an inference model like the OpenAI o series, but it is optimized for agent tasks, allowing it to not only respond simply but also use tools. It also performs well in mathematical and coding tasks.

Kimi K2 has been released in two versions: the base model 'Kimi-K2-Base' and the post-trained model 'Kimi-K2-Instruct'. The following figure shows the benchmark scores of 'Kimi-K2-Instruct', 'DeepSeek V3', 'Qwen3-235B', 'GPT-4.1', 'Claude 4 Opus', 'Claude 4 Sonnet', and 'Gemini 2.5 Flash'. Kimi-K2-Instruct scored higher than the open models DeepSeek V3 and Qwen3-235B in all tests, and beat commercial models such as GPT-4.1 and Claude Sonnet 4 in some tests.



Below is an example of how Kimi K2 can be used as an AI agent. When you tell it to plan a trip, it will make the plan by using various tools such as 'getting dates,' 'searching for information on the web,' and 'checking the email inbox.'



In the end, a visually easy-to-understand plan was output.



In addition, users who have actually used Kimi K2 have reported that they were able to create a game in one go just by entering the prompt, 'Create a simple breakout game as a single html page.'




Kimi K2 is available via API , and the Kimi-K2-Base and Kimi-K2-Instruct model data are distributed on Hugging Face.
