Moonshot AI is committed to solving ambitious "moonshot" problems that will lead humanity to AGI. We embrace open source, and contributed the following projects to the community:
- Kimi K2: our latest open-source Mixture-of-Experts model with 32B activated parameters and 1T total parameters. It achieves state-of-the-art performance in frontier knowledge, math, and coding among non-thinking models.
- Mooncake: pioneered the idea of KV-centric disaggregated LLM serving, winning the Best Paper award at FAST 2025. We released code and data corresponding to our paper.
- Kimi-K1.5: Scaling Reinforcement Learning with LLMs. We released our tech report on building an o1-level multi-modal reasoning model.
- Moonlight for our paper Muon is Scalable for LLM Training. We released (i) checkpoints for SOTA small models; (ii) code for our improved Muon optimizer.
- MoBA: Mixture of Block Attention for Long-Context LLMs. We released code and paper for our looong-context LLM technique.
- Kimi-VL: Mixture-of-Experts Vision-Language Model for Multimodal Reasoning, Long-Context Understanding, and Strong Agent Capabilities
- Kimina-Prover Preview: Towards Large Formal Reasoning Models with Reinforcement Learning. We released technical report, model weights and a rectified version of miniF2F-test benchmark.
- Kimi-Audio: Universal audio foundation model that handles diverse tasks like speech recognition, audio understanding, audio-to-text chat, speech-to-speech conversation. We released the technical report, model weights and evaluation toolkit.
- Kimi-Dev: A Strong and Open-source Coding LLM for Issue Resolution. Kimi-Dev-72B achieves 60.4% performance on SWE-bench Verified.
- MoonshotAI-Cookbook: examples on how to use our API service.
- moonpalace: debugging tool for our API service.
