OpenRouter's stealth model Ox Alpha sparks guessing game over its identity
AccBalanced · x · 2026-08-21
OpenRouter launched a stealth model, Ox Alpha, described as a frontier model built for efficient coding, sustained agentic work, and production use, with a 1M token context window and text/image/video input.
Andrew Curran notes its identity remains a mystery: last night the top candidate was a new GLM release from Zhipu, but confidence has since dropped. He has opened a thread collecting guesses and test results.
