Kimi K2

Kimi K2 is a state-of-the-art large language model that leverages a Mixture-of-Experts architecture to deliver exceptional efficiency and performance. Unlike traditional models, Kimi K2 dynamically activates only a subset of its 384 experts (8 per token, plus one shared expert), enabling it to rival proprietary models like GPT-4 and Claude 4 Sonnet while being significantly more cost-effective.

Pre-trained on an impressive 15.5 trillion tokens using the innovative MuonClip optimizer, Kimi K2 ensures stable, high-quality performance across diverse tasks.Available in two variants:

  • Kimi-K2-Base: Ideal for researchers and developers who want full control for fine-tuning and building custom AI solutions.
  • Kimi-K2-Instruct: A post-trained model optimized for general-purpose chat and agentic workflows, ready for immediate deployment.

With a 128,000-token context window, Kimi K2 excels at processing vast amounts of data, making it perfect for complex, multi-step tasks that require long-context understanding.
