Moonshot AI Stops New Kimi K3 Signups Amid GPU Shortage

Moonshot AI hit a major speed bump this week after the launch of its Kimi K3 model triggered a massive wave of user interest. Within 48 hours of the release on July 16, the company announced a temporary freeze on new subscriptions to ensure the system remains stable for existing users. The surge in traffic pushed the firm's available GPU resources to their absolute breaking point.

To manage the strain, the company is also splitting its membership tiers. Future users will choose between standard access for web and app usage or a specific plan tailored for coding tasks. This strategy is designed to balance computing power more efficiently as the company works to scale its physical hardware infrastructure.

The Kimi K3 model has generated significant buzz thanks to its technical features, which include a 1 million token context window and strong rankings from third party evaluators. With a valuation reportedly moving toward $30 billion and plans for a potential Hong Kong IPO on the horizon, this growth challenge marks a pivotal moment for the Chinese startup as it competes with global tech giants.

Investors are watching closely to see how quickly the company can expand its capacity. While the pause is a limitation for new customers, it highlights the heavy demand for affordable and powerful AI models. Moonshot AI has not provided a firm date for reopening subscriptions, but the team confirmed that infrastructure upgrades are currently underway.
