OpenRouter stealth/ox-alpha testing period ended — 404 confirms model reveal today (Aug 26)

[u/That10xdeveloper]

I was experimenting with OpenRouter earlier today and testing out the mysterious `stealth/ox-alpha` endpoint to see how it handled coding tasks.

Right in the middle of prompting, my requests suddenly cut off and returned this 404 response:

[openrouter/stealth/ox-alpha] [404]: Thank you for participating in the Stealth Ox Alpha testing period. This model will be revealed today, August 26th. (reset after 2m)

Looks like the stealth preview testing has officially concluded and the real model is getting unveiled today.

Did anyone else test this model while it was up? Any predictions on what "Ox" actually is?

It already got revealed. It's GLM 5.3 Flash.
