About Moonlight-A3B

Moonlight-A3B is a compute-efficient Mixture of Experts (MoE) large language model developed by Moonshot AI. It is notable for being the first successful scaling up of the Muon optimizer. The model has 16 billion total parameters and is designed for text generation. It is part of a collection of Moonshot AI models, including Kimi K2.5, Kimi-K2, and others, and is available as an open-source model on Hugging Face.
