The deployment marks a significant test of China’s ability to handle large-scale global inference workloads on home-grown hardware, as Beijing seeks to

reduce reliance on advanced processors from US market leader Nvidiaamid tight export controls.During its preview, Ox Alpha rapidly surged to the top of global usage rankings. According to OpenRouter data on Thursday, the model ranked first among coding systems on the platform, accounting for 10.3 trillion tokens, or nearly 31 per cent of its total weekly volume.
