How to Use Ox Alpha with Open Design for Free AI UI Generation
A step-by-step guide to connecting the free Ox Alpha model to Open Code and Open Design to generate real, exportable HTML/CSS interfaces.
What is Ox Alpha and why does it matter for UI design?
Ox Alpha is a stealth AI model currently available for free through Open Code. Nobody outside its creators knows who built it. It could be a next-generation release from an existing lab, or something entirely new. Open Code lists it with a 1 million token context window, multimodal support, and zero data retention, and the provider has claimed very high daily token capacity, meaning you can use it heavily without hitting caps during the free window. What sets it apart isn’t mystery, it’s output quality. Ox Alpha performs unusually well at front-end and UI generation tasks compared to most other coding models, producing interfaces with real visual hierarchy instead of the generic AI look.
TL;DR
- Ox Alpha is a free, anonymous stealth model on Open Code that scores especially well on visual, front-end-heavy tasks like animated interfaces and SVG work.
- The model is free for a limited window, with the free period reportedly ending around August 27, after which pricing and identity may change.
- Open Design is a free, Apache 2.0 licensed, local-first design tool that is model agnostic, meaning it can run on top of Ox Alpha inside Open Code instead of a proprietary backend.
- Open Design ships with prebuilt design systems modeled on products like Linear, Stripe, Vercel, Airbnb, Apple, and Notion, which act as strict visual rules rather than vague style suggestions.
- Everything Open Design produces is real HTML and CSS, not a flat mockup image, so it can be previewed, edited, exported, and handed to a coding agent for integration into an actual codebase.
- Because Ox Alpha is a stealth alias, the model behind the name can change at any time, so results today aren’t guaranteed to match results next month.
- Since the provider is unknown and data handling claims can’t be independently verified, it’s safer to use this stack for prototypes and personal projects rather than sensitive production code.

How do you install Open Code and connect Ox Alpha?
Open Code is the coding agent harness that currently hosts Ox Alpha. Setup is a short terminal process:
- Install Open Code by running
curl -fsSL https://opencode.ai/install | bashin a terminal. If Node.js is already installed,npm install -g opencode-aiworks as an alternative. - Navigate into a project folder and run
opencodeto launch it. - If you haven’t linked an account yet, run the
/connectcommand, choose Open Code Zen, follow the authentication link, sign in, and generate an API key. Paste that key back into the terminal prompt. - Run
/models, search for Ox Alpha, and select it.
During the free period, using Ox Alpha through this route doesn’t draw down any paid Zen balance. Once connected, you can prompt it directly for front-end work, for example asking for a full landing page with a hero section, features grid, pricing block, and responsive scroll animations. Reports from hands-on testing describe results with clean spacing, restrained use of accent colors, and subtle animation, a contrast to the more generic “purple gradient card” look common in AI-generated pages.
What is Open Design and how is it different from a plain chat prompt?
Open Design is an open-source, Apache 2.0 licensed design workspace built to be local-first and model agnostic. Instead of typing a design request into an empty chat box and hoping for the best, it gives whatever model you connect a structured workflow: prebuilt design skills, a library of design systems, and a plug-in ecosystem, reportedly covering more than 100 skills and around 150 design systems. It supports use cases beyond single landing pages, including mobile interfaces, dashboards, and slide decks.
The key technical difference is output format. Open Design generates actual HTML and CSS rather than a static image mockup. That means a design can be previewed live, edited, exported, and handed directly to a coding agent (Open Code, Claude Code, Cursor, or similar) to integrate into a real project, whether that’s a plain HTML site or a React or Next.js codebase. Nothing has to be rebuilt from scratch after the design phase, which is normally the bottleneck when using image-based design tools.
How do you set up Open Design with Ox Alpha?
Installation is straightforward:
- Go to the Open Design website and download the installer for your operating system, or grab the same files from the project’s GitHub releases page.
- Run the installer and complete the onboarding questions.
- On the homepage, Open Design automatically detects any coding agents already installed on your machine, including Open Code, Claude Code, Codex, and Cursor.
- Select Open Code as the agent, then choose Ox Alpha as the model.
From there, start a new project, choose a skill (web prototype, for example), and pick a design system. This last step matters more than it looks. A design system gives the model concrete constraints, palette, typography, spacing rules, component shapes, motion behavior, and things to avoid, rather than a loose instruction like “make it modern.” Pairing a model that’s already strong on front-end tasks with a strict visual contract is what produces consistent, non-generic results.
Is the Ox Alpha and Open Design combination worth trying right now?
For anyone building interfaces with AI, yes, at least while the free window lasts. You get a model that performs well specifically on visual and interactive front-end tasks, paired with a genuinely open-source design tool that outputs editable code instead of throwaway screenshots. The entire stack costs nothing to run during the promotional period. Testing with prompts like a full landing page for a fictional product, including a hero section, an interactive preview element, a pricing table, and a call to action, has produced pages with consistent spacing, coherent typography, and accent colors that carry through the whole layout rather than fading out after the first section.
That said, there are real caveats. The free period for Ox Alpha has a stated end date around August 27, after which pricing and even the model’s identity behind the alias could change entirely. Stealth models can be swapped without notice, so a workflow that performs a certain way today isn’t guaranteed to behave identically next month. And while Open Code claims zero data retention for this model, the provider is unknown, so treating this as a tool for prototypes, personal projects, and open-source work is more sensible than routing sensitive company code through it.
Frequently Asked Questions
What is Ox Alpha exactly?
It’s an anonymous, stealth AI model available through Open Code, with an unconfirmed identity. Its output quality on front-end and design tasks has drawn attention, and it currently offers a 1 million token context window with multimodal support during its free period.
Is Open Design a paid tool?
No. Open Design is free and open-source under an Apache 2.0 license, built to be local-first and to work with multiple AI models rather than locking users into one provider.
Can I use Open Design with models other than Ox Alpha?
Yes. Open Design is model agnostic and detects coding agents like Open Code, Claude Code, Codex, and Cursor automatically, letting you swap in whichever model you prefer.
Does Open Design just generate images of designs?
No. It outputs real HTML and CSS that can be previewed, edited, exported, and handed off to a coding agent for integration into an actual project, rather than a flat mockup that needs to be recreated in code.
Will Ox Alpha stay free?
Based on current information, the free period is expected to end around August 27, after which pricing and the model’s underlying identity may change since it’s distributed under a stealth alias that can be swapped at any time.
