Mystery AI model Ox Alpha draws developers with free access

Ox Alpha, a free "stealth model" launched August 20 on OpenRouter, OpenCode, Cline, and Nous Research's portal+, reads up to ~1 million tokens and takes text, image, and video input. A viral 10-task DeepSWE sample showed 80% first-pass, but full 113-task runs landed near 63%, roughly level with GPT-5.6 Sol.
