Ox Alpha unlimited free: What the Preview Offers
Ox Alpha unlimited free is a search phrase used for the model’s current no-cost preview access. Ox Alpha is not presented as a conventional consumer chatbot or a game. It is a stealth reasoning model built for coding, sustained agentic work, production workloads, and tasks that combine text with visual context.
OpenRouter lists the model under the identifier stealth/ox-alpha. The provider remains anonymous during the preview, while OpenRouter acts as the routing platform rather than the model’s developer or owner. The current listing shows free input and output pricing, but preview access should be treated as temporary and subject to change.
The model supports text, image, and video input with text output. This makes it useful for more than ordinary code completion. You can provide a screenshot for interface analysis, attach visual references during a front-end task, or ask the model to interpret video content before producing a written response.
Video Highlights:
- Ox Alpha is introduced as a stealth model with a free preview period.
- The workflow demonstrates access through OpenRouter and OpenCode.
- Coding examples include a car-detailing landing page and a 3D solar-system visualization.
- The model is tested with long-form front-end and visual development tasks.

OpenRouter and OpenCode Access Compared
There are two practical ways to use Ox Alpha in the current ecosystem. OpenRouter provides direct model access through its playground and API-compatible endpoint. OpenCode can connect to OpenRouter as an external provider, allowing the model to operate inside a terminal-based coding workflow.
The best choice depends on how you work. OpenRouter is simpler for testing prompts and making API requests. OpenCode is more useful when you want an agent to inspect files, edit a project, and continue through several development stages.
| Access route | Best for | Requirements | Main advantage |
|---|---|---|---|
| OpenRouter Playground | Prompt testing and quick experiments | OpenRouter account and API key when required | Fastest way to evaluate responses |
| OpenRouter API | Applications and custom integrations | API key and compatible request format | OpenAI-compatible development workflow |
| OpenCode with OpenRouter | Terminal-based coding projects | OpenCode installation, provider setup, API key | Project-aware agentic work |
| OpenCode plan access | Users already working inside OpenCode | Availability depends on the current plan | Convenient in-product model switching |
To use the API, create an OpenRouter key and select the model slug stealth/ox-alpha. OpenRouter states that its API is OpenAI-compatible, so many existing SDK patterns can be adapted by changing the base URL, authentication value, and model name.
OpenCode adds a configuration layer between your local project and the provider. After connecting OpenRouter, use the model selector to search for Ox Alpha. If more than one Ox Alpha route appears, verify the provider and pricing before sending a large request.
Use OpenRouter for a quick capability test. Use OpenCode when the model needs to inspect directories, modify files, run development commands, or iterate on a project.
What “Unlimited” Should Mean in Practice
The phrase “unlimited free” describes the unusually generous preview access reported around the model, not a permanent service guarantee. The reference material describes very high capacity, including a reported 100 trillion tokens per day, while OpenRouter’s live listing confirms free pricing and monitored availability.
Those are different concepts:
- Free pricing means the displayed token price is zero.
- High capacity refers to the amount of service the provider may make available.
- Unlimited usage would require a clearly stated, enforceable policy.
- Availability can still be affected by outages, throttling, provider changes, or preview closure.
Treat the model as a valuable free preview rather than a permanent substitute for a paid production service.
Step-by-Step Ox Alpha Setup Guide
Follow these steps to connect Ox Alpha through OpenRouter and, if needed, use it inside OpenCode. Keep your API key private and test with a small request before assigning a large project.
Open the Ox Alpha Listing
Visit the Ox Alpha model page on OpenRouter and confirm that the model identifier is stealth/ox-alpha. Review the current price and provider details before continuing.
Create an OpenRouter API Key
Sign in to OpenRouter, open the API key section, and create a key for your project. Copy it once and store it in an environment variable or another secure secrets manager.
Install or Open OpenCode
If you want a terminal coding workflow, install OpenCode from its official site or launch your existing installation. Start from a test project directory instead of exposing an unrelated production repository.
Connect the Provider
In OpenCode, open the model or provider selector, choose OpenRouter, and enter the API key when prompted. Search for Ox Alpha and select the free route shown by the current configuration.
Run a Small Test Prompt
Ask for a limited task such as explaining a file, drafting a component, or identifying an error. Check the output, tool behavior, and project changes before moving to a larger request.
| Setup stage | Action | Verification |
|---|---|---|
| Account | Sign in to OpenRouter | Dashboard loads successfully |
| Key | Generate an API key | Key is stored privately |
| Provider | Select OpenRouter in OpenCode | Provider connection is accepted |
| Model | Search for stealth/ox-alpha | Ox Alpha appears in the selector |
| Test | Send a small coding request | Response returns without unexpected changes |
A strong first prompt should define the goal, project boundaries, expected files, and validation steps. Instead of writing “build an app,” specify the framework, visual direction, required interactions, and how the result should be tested.
For example, ask Ox Alpha to create a single-page landing page, identify the files it will change, use a restrained color palette, and verify that images and animations do not produce broken states. This gives the agent enough structure while preserving room for implementation decisions.
Begin with a disposable folder or a version-controlled branch. Review every file change and command result before merging generated work into an important project.
Best Uses, Limits, and Privacy Checks
Ox Alpha is most compelling when a task benefits from sustained context and visual reasoning. The preview has been used for front-end generation, interactive visualization, and software-engineering prompts that require several connected decisions.
| Use case | Why it fits | Recommended prompt detail |
|---|---|---|
| Front-end prototypes | Combines design direction with implementation | Framework, layout, animation behavior, image rules |
| Codebase refactoring | Supports extended project context | Target files, constraints, tests, acceptance criteria |
| Screenshot analysis | Accepts image input | Identify elements, compare states, list actionable fixes |
| Video understanding | Supports video input | Specify timestamps, questions, and desired text format |
| Agentic development | Handles multi-step workflows | Permissions, tools, checkpoints, and rollback plan |
The model is not automatically correct simply because it produces polished output. Generated interfaces can contain accessibility gaps, incorrect assumptions, missing error states, or dependencies that are unsuitable for your project. Review code quality, security, licensing, and performance before deployment.
The OpenRouter listing also includes an important privacy condition: prompts and completions are retained by the third-party provider, while the provider states that they are not used for training. Retention is still relevant. Do not send passwords, private customer records, confidential source code, proprietary documents, or regulated information unless your organization has approved that workflow.
Practical Prompt Pattern
Use this structure for reliable coding requests:
- Role and goal: Explain what the agent should build or investigate.
- Project context: Name the framework, directory, runtime, and existing constraints.
- Design requirements: Describe layout, interaction, typography, and visual boundaries.
- Execution rules: Ask the model to inspect before editing and summarize each change.
- Validation: Require tests, a build check, or a manual verification checklist.
Before Sending a Large Request:
- Confirm the model slug is stealth/ox-alpha
- Store the OpenRouter API key outside the source code
- Use a version-controlled branch or disposable project folder
- Remove confidential data from prompts and attachments
- Define validation steps and review generated changes
Free pricing does not mean that prompts are private by default. Review the current provider terms before sending sensitive code, business data, images, or video.
