"Ox Alpha" stealth reasoning model lands on OpenRouter — free, 1M context, vision-capable
A new reasoning model, "Ox Alpha," is now live on OpenRouter as a free stealth offering from an anonymous third-party provider. It's aimed at long-horizon software engineering, sustained agentic work, and production loads, with a 1M-token context and support for text-plus-visual workflows. OpenRouter routes it but stresses it isn't the developer — prompts stay with the provider and aren't used for training. The anonymity makes it both intriguing and hard to benchmark against known models.
