Ox Alpha: Mysterious stealth AI model debuts on OpenRouter
Ox Alpha, a mysterious ‘stealth’ AI model, has appeared on the OpenRouter and OpenCode platforms, sparking intense debate within the developer community. Designed for coding, long-horizon agentic tasks, and production workloads, the model features a massive 1,048,576-token context window and supports multimodal inputs including text, images, and video, though it rejects audio.
The model’s sudden release has been characterized by its extreme scale and anonymity. It was offered for free during a limited preview period, with claims of a daily processing capacity of up to 100 trillion tokens. This massive throughput has already driven significant usage, with some reports indicating the model processed over 11 trillion tokens in just three days, setting new records on OpenRouter.
While the developer remains officially anonymous, widespread speculation has emerged regarding its origin. Many analysts and researchers point toward Chinese technology firms, specifically Zhipu AI, citing similarities in tokenizer behavior and API response patterns with the GLM series. Other theories suggest it could be an unannounced version of Microsoft’s MAI models. Industry leaders, including Stripe CEO Patrick Collison, have praised the model’s performance, noting it is ‘very impressive.’
