■ AI-SUMMARIZED FROM 5 SOURCES ▸ TIMELINE

Moonshot AI has temporarily halted new subscriptions for its Kimi K3 chatbot after demand nearly maxed out server capacity within 48 hours. The company is also restructuring its subscription tiers.

The Chinese AI startup cited unprecedented demand for Kimi K3 as the reason for the pause. Over two days, user traffic pushed the system close to infrastructure limits, prompting Moonshot to freeze new sign-ups to maintain service quality for existing subscribers. The suspension comes as Moonshot simultaneously reworks its pricing and plan structure. The company did not specify when new subscriptions would resume or details of the revised tier system. Kimi K3 has gained traction in China's competitive AI chatbot market, competing against services like ChatGPT and Claude. The rapid uptake suggests strong regional demand for advanced language models. Moonshot AI did not disclose current subscriber numbers or technical specifications of its infrastructure. The pause represents a common constraint for AI startups scaling compute-intensive services amid surging user demand.
