Ox Alpha

Researchers say malformed Ox Alpha requests exposed Zhipu-specific routes, error codes, and an internal class name. Independent vision comparisons also argue against speculation that the stealth model is Gemini.

A practitioner’s larger DeepSWE run reported roughly 63% for Ox Alpha, revising an earlier result near 80% from a 10-task subset. Testers report capable long-task work but note dead code and incomplete fixes.

OpenRouter is testing Ox Alpha, a free stealth model with a 1M-token context window. The model accepts text, image, and video inputs and is offered with zero data retention during the test.
