A few days ago, a new AI model quietly appeared on OpenRouter.
Its name is Ox Alpha.
Nobody officially knows who made it.
It is listed as stealth/ox-alpha, described as a reasoning model built for coding and sustained agentic work, and it comes with some pretty wild specs, including a 1,048,576-token context window and up to 131,072 output tokens. The developer is simply listed as an anonymous third-party provider.
Rather than throw benchmarks at it, I did what I usually do when I want to get a feel for a coding model.
