About

The site behind the stealth model.

oxalpha.org is a free, no-login way to chat with Ox Alpha — the frontier reasoning model that showed up in stealth and had everyone talking. We're not the lab that built it; we just made it effortless to try.

What is Ox Alpha?

Ox Alpha is a reasoning-first model that appeared on OpenRouter in August 2026. It's built for coding, long-horizon agentic work and complex problem solving, with a 1,000,000-token context window and multimodal (text and vision) input.

Like other stealth models, it was published anonymously so its makers could gather real-world feedback before an official launch. Nobody has confirmed which lab is behind it — and that's part of the fun.

What this site is

oxalpha.org is an independent project and is not affiliated with the model's creators. We provide a clean, fast chat interface and a landing page that explains what the model can do.

While Ox Alpha is in its stealth period, using it here is completely free — no account, no card, no VPN. Open the chat and start typing.

How we run it

Your messages are routed through OpenRouter to a dedicated provider serving the model, and responses stream back to your browser in real time — no routing guesswork and no queue.

The interface renders Markdown, syntax-highlighted code and the model's visible reasoning, so you can watch it think before it answers.

Privacy by default

We don't require any personal information and we don't store your conversations on our servers. Prompts and completions are processed by the upstream model API to generate responses.

For the details, see our Privacy Policy. As with any AI service, avoid sharing sensitive data.
