Ox Alpha is an anonymous third-party reasoning model focused on coding, long-horizon agentic work, and production workloads. It's currently free on OpenRouter with a 1M context window, 1s P50 latency, and 69 tok/s throughput. The post doesn't disclose who built it, parameter count, or how long the free tier lasts. Usage data shows Claude Code and Nous Research's Hermes Agent already pushing significant token volume—treat it as a coding agent model worth testing, but anonymity and free pricing make long-term reliability uncertain.

Why it matters: Anonymous reasoning model drops free with 1M context, 1s P50 latency, 69 tok/s, targeting coding and sustained agentic work. Developer, param count, and free-tier duration all undisclosed — big info gaps — but Claude Code and Nous Research are already using it, so it's not vap...
