“Ox Alpha,” an anonymous “stealth” model that appeared on OpenRouter earlier today (August 20, 2026).
It’s a reasoning model positioned for coding, sustained agentic work, and production use, with a 1,048,576-token context window, a 131,072-token output cap, and text/image/video input — listed as stealth/ox-alpha on OpenRouter. It’s free during this preview window, with the operator claiming near-unlimited rate limits and 100 trillion tokens/day of serving capacity.
There is some buzz on Twitter that it is frontier or even better at coding.

GLM and Ox Alpha went down at the same time
@ae could be someone that just used their model and fine tuned it. Cursor has done it in the past. This was already priced in.
@JasonMendoza2008 certainly could be the case. but pliny has high credibility, so I do not consider this "already priced in".
