On the afternoon of July 16, Cursor announced to its developer community that it would be implementing geolocation-based access restrictions, with certain models no longer accessible to Chinese IP addresses. Consequently, the company initiated a refund process for affected users. This move prompted Chinese developers to shift their focus towards domestic large models. According to OpenRouter platform data, the domestic large models Kimi K2 and Musk's newly launched Grok4 have witnessed a remarkable surge in call volume, topping the platform's growth chart. Specifically, they have peaked at over 10 billion tokens in daily call volume. Launched by Moonshot AI, Kimi K2 boasts an API pricing that is approximately one-fifth that of Claude's medium-sized model, Sonnet, providing a substantial cost advantage. This pricing strategy has garnered significant interest from developers, who are eager to try and integrate Kimi K2, thereby further propelling its market share.
