Moonshot AI, a Chinese startup, has suspended new subscriptions for its Kimi K3 model just 48 hours after launch due to unexpectedly high demand exceeding its computational capacity. The company is reserving all available resources for existing subscribers.
The Kimi K3 is an open-weight model with 2.8 trillion parameters—the largest in its category—delivering performance comparable to Claude Fable and OpenAI's GPT-5.6 Sol. The surge in interest demonstrates strong market appetite for capable, openly available large language models.
