Moonshot AI, a Beijing-based artificial intelligence startup, temporarily pauses new subscriptions for its Kimi K3 model after demand surges beyond its current compute capacity. In statements posted on X, the company says the past 48 hours have brought usage close to the limits of available infrastructure, adding that its GPUs are “feeling it.” Multiple outlets report that existing paid users are not affected and that Moonshot is focusing on serving current subscribers while it adds capacity. The company also says it will reopen subscription slots in batches as additional computing resources come online.

Reports describe Kimi K3 as a newly launched large-language model that drew unusually high interest shortly after release. Several outlets note it is an open-weight model with a reported 2.8 trillion parameters, and some mention it is served through a cloud API while the company prepares to release the model’s weights later in July. The episode is framed as a sign of the practical challenges AI labs face when popularity outpaces available hardware, including the allocation of limited computing chips.
