Ox Alpha: Free reasoning model from anonymous provider on OpenRouter
Stealth Model
OpenRouter now hosts Ox Alpha, a free reasoning model for coding and agentic work, with a 1M-token context window. The provider is anonymous during this preview, and prompts are retained but not used for training. It is served by Stealth and supports text, images, and video input.
Ox Alpha is a stealth model. It is developed and operated by a third-party provider who has chosen to remain anonymous during this preview.

OpenCode offers this with ZDR agreement in place. Seems better than OpenRouter if you want to test it out: https://x.com/opencode/status/2090544355824038300

It's Chinese. Won't answer anything about Tiananmen Square but will gleefully give you instructions to perform various electronic warfare attacks that opus and fable instantly refuse.
Side tangent, why is fable so weird about questions involving "Welch's method"? Even really trivial ones it'll shut down frequently. CFAR and STFT are both totally fine but Welch's is apparently taboo, it's wild.

I highly recommend feeding all your proprietary data and confidential personal information into this model as quickly as possible. What could possibly go wrong?!
In terms of equivalence of suspicion, this is the external inference provider equivalent of getting free steak that was smuggled out of a grocery store inside somebody's pants.

"Prompts and completions are retained by the provider and are not used for training..."
I'm curious what the model provider is using the prompt/response pairs for, in that case. They aren't offering a model for free without their name on it for no reason.

It did an absolutely terrible job at generating CSS, where I instructed it to finish implementing a bright and dark theme based on a palette through the use of `color-mix()` and it just went ahead, removed everything I pre-added and replaced it with hardcoded hexadecimal color values.

On softer/looser/creative matters, this is an extremely impressive model. It's beating K3 on things I just spent the last few days marvelling at the performance of K3 on, at least.
Visual reasoning is not great (unsurprising).

Model is suspiciously fast and has a low reported output token count (using via OpenRouter's Chat), both of which aren't representative of models from the big Chinese labs. Odd.

Been running tests, seems pretty capable but less knowledgeable, and the CoT reminds me of GLM, so if I had to guess it's almost definitely a Chinese model, and likely a western RL trained variant of a Chinese open weight.
