Moonshot AI Pauses New Kimi K3 Subscriptions Amid GPU Capacity Crunch

Moonshot AI has temporarily paused new subscriptions for its Kimi K3 model after a surge in demand pushed the company close to the limits of its computing capacity. The Beijing-based startup said existing subscribers are unaffected and that it is adding GPU capacity as quickly as possible, with new sign-up slots expected to reopen in batches. The move highlights the infrastructure strain facing fast-growing Chinese AI companies as they compete to serve a rapidly expanding user base. Reuters also reported that the capacity crunch comes as Moonshot AI weighs new fundraising and a possible Hong Kong listing.
