- Best approach: Treat free access as temporary and avoid depending on it for critical production workloads.
Ox Alpha Free How Long: The Short Answer
Ox Alpha is currently listed as free on OpenRouter, but the available information does not provide a guaranteed end date. The model was released on August 20, 2026, and remains presented as a stealth preview operated by an anonymous third-party provider.
That means “free” describes the current pricing shown by the provider, not a permanent promise. OpenRouter reports $0 input pricing and $0 output pricing, while the model page also labels Ox Alpha as a preview. Access, capacity, rate limits, and pricing may change as testing continues.
Video Highlights:
- Ox Alpha is presented as a stealth reasoning model for coding and agentic work.
- Testing covered vector graphics, interactive 3D scenes, front-end design, game physics, and full-stack applications.
- The model supports text, image, and video input with a reported 1 million-token context window.
- The reported coding benchmark result reached 80% on 10 DeepSWE tasks in one independent test.
The safest interpretation is straightforward: Ox Alpha is free for the duration of its current preview availability, but there is no published schedule confirming how long that status will last. Users should check the official Ox Alpha OpenRouter page before important projects because the listing is the most direct place to verify price and provider status.
| Question | Current answer |
|---|---|
| Is Ox Alpha free now? | Yes, OpenRouter lists free input and output pricing. |
| Is the free period permanent? | No permanent access guarantee is published. |
| When was it released? | August 20, 2026 |
| Is there an announced end date? | No public end date is listed. |
| Where is it available? | Through OpenRouter’s Ox Alpha listing and compatible API tools. |
Do not assume that today’s $0 pricing will continue indefinitely. Save important prompts, monitor the model page, and keep a fallback model ready for production work.
What Ox Alpha Offers During the Free Preview
Ox Alpha is not described as a game or entertainment platform. It is a multimodal reasoning model aimed at software engineering, sustained agentic work, complex reasoning, and production-oriented workflows. Its most notable feature is the combination of long context, visual input, and coding-focused output.
OpenRouter lists a 1M context window, while the model accepts text, images, and video as input and returns text. This makes it suitable for tasks that require large codebases, visual references, interface screenshots, or analysis of recorded demonstrations.
Coding
Ox Alpha is designed for long-horizon software engineering, debugging, and multi-file development tasks.
Visual Context
Text, image, and video input can be combined when a task requires more than written instructions.
Agentic Work
The model is positioned for sustained workflows that involve planning, tool use, and repeated revisions.
Interactive Builds
Testing showed useful results for front-end pages, 3D scenes, physics demos, and full-stack applications.
The available testing examples suggest that Ox Alpha performs particularly well when the task has a clear functional target. A 3D pill organizer included separate compartments, labels, opening animations, and interactive controls. A scissor lift demonstration maintained connected moving parts while the user adjusted height with a slider.
The front-end test produced a polished landing page with live preview content, animated updates, a workflow section, pricing blocks, and an FAQ area. A full-stack task board also connected a React interface with a Python FastAPI backend and SQLite storage.
| Capability | Reported support | Practical use |
|---|---|---|
| Text input | Yes | Prompts, specifications, code, and analysis |
| Image input | Yes | Screenshots, diagrams, mockups, and visual references |
| Video input | Yes | Demonstrations, motion review, and visual task context |
| Context window | 1M tokens | Large repositories and long technical sessions |
| Output type | Text | Code, explanations, plans, and structured responses |
| Listed price | $0 input / $0 output | Preview experimentation through the listed provider |
The reported results should be treated as useful signals rather than a universal ranking. The coding test covered 10 DeepSWE tasks and produced an 80% score, but a small benchmark sample cannot predict every workload. For reliable evaluation, compare Ox Alpha with your usual model using the same prompts, tools, codebase, and test suite.
Use Ox Alpha for prototyping, code exploration, multimodal experiments, and interactive demos first. These tasks let you evaluate its strengths without making your workflow dependent on uncertain preview pricing.
How to Access Ox Alpha While It Is Free
The simplest access method is OpenRouter’s web playground. API users can call the model with the identifier stealth/ox-alpha through an OpenAI-compatible request format. An API key is still required for API access even when the model’s listed token price is zero.
Follow these steps to verify the current status and make a first request.
Open the Model Listing
Visit the Ox Alpha page on OpenRouter and confirm that the price still shows Free. Check the release information, provider notice, and any current access restrictions before starting.
Choose Playground or API Access
Use the playground for quick experiments without writing code. For an application, create an OpenRouter API key and store it as an environment variable named OPENROUTER_API_KEY.
Select the Correct Model Slug
API requests should use stealth/ox-alpha. The model slug is separate from the display name, so copying the exact identifier reduces request errors.
Start With a Controlled Prompt
Test a small coding, reasoning, image, or video task first. Confirm that the returned answer matches your requirements before sending large files or long-running jobs.
Record Results and Monitor Pricing
Save useful outputs, note response speed and tool behavior, and revisit the listing periodically. Preview pricing can change without matching your original assumptions.
A minimal shell setup from the model’s quick-start flow looks like this:
export OPENROUTER_API_KEY=sk-or-v1-...
Streaming can be enabled with "stream": true, allowing the application to receive output progressively. This may improve the experience for long responses, although it does not change the model’s listed token price.
| Access method | Requirements | Best for |
|---|---|---|
| Playground | OpenRouter account or sign-in | First tests and prompt comparison |
| OpenAI-compatible API | OpenRouter API key | Applications and automated workflows |
| Streaming request | API access plus stream: true | Long responses and live interfaces |
| Multimodal request | Supported image or video input | Visual analysis and interactive prototypes |
Before sending a large request, verify three items: the listing still shows Free, the model slug is stealth/ox-alpha, and your request uses supported input content.
How Long Will the Free Access Last?
There is no confirmed public duration for the free period. The available listing identifies Ox Alpha as a stealth model released on August 20, 2026, and says it is developed and operated by a third-party provider that has chosen to remain anonymous during the preview.
This wording matters. A preview can remain free for an unknown period, move to paid pricing, become capacity-limited, or disappear from a platform. None of those outcomes is confirmed for Ox Alpha, so the responsible answer is to distinguish current facts from future possibilities.
| Status item | What is confirmed | What remains unknown |
|---|---|---|
| Availability | Ox Alpha is listed on OpenRouter in August 2026 | How long the listing will remain available |
| Pricing | Input and output are listed at $0 | Whether paid pricing will begin later |
| Provider | One anonymous third-party provider is listed | The provider’s identity and long-term plans |
| Capacity | The page reports current performance and uptime data | Future rate limits or traffic restrictions |
| Data terms | Prompts and completions are retained by the provider and not used for training under the stated preview terms | Whether future terms will change |
Users should also distinguish free token pricing from unlimited practical access. Even with a zero listed price, access can be affected by queueing, throughput, account policies, provider capacity, request limits, or service interruptions.
OpenRouter’s displayed performance data includes a provider latency figure, throughput measurements, and recent uptime information. These values describe observed service behavior during the reported period; they should not be read as a promise that every future request will perform identically.
A sensible planning rule is:
- Use the current free preview for evaluation and experimentation.
- Keep a local archive of prompts, generated code, and test results.
- Avoid making a business-critical pipeline depend on one anonymous provider.
- Recheck pricing and terms before increasing usage.
- Maintain an alternative model for continuity.
The accurate answer to “how long is Ox Alpha free?” is “until the provider or platform changes the preview terms.” No specific end date is currently published.
Is Ox Alpha Worth Using Before Pricing Changes?
Ox Alpha is worth testing if your goal is to evaluate long-context reasoning, multimodal prompts, coding assistance, or interactive application generation. The free listing lowers the barrier to comparison, especially for developers who want to test the same task across several models.
Its reported strengths are broad. The testing examples included SVG illustration, 3D modeling, 3D kinematics, a front-end landing page, a basketball physics demo, and a React-Python full-stack task board. These examples indicate flexibility across creative and technical workflows.
However, broad capability does not remove the need for verification. Generated code should be reviewed, dependencies should be checked, and application behavior should be tested locally. Visual polish can also vary depending on prompt detail, input quality, and the complexity of the requested interaction.
| Workflow | Why test Ox Alpha | What to verify |
|---|---|---|
| Large codebase review | 1M context may support extensive project context | Accuracy, omissions, and context handling |
| Front-end prototype | Reported strength in polished layouts and live previews | Responsive behavior and maintainability |
| 3D interaction | Testing showed models with animation and controls | Geometry, performance, and edge cases |
| Full-stack prototype | A React, FastAPI, and SQLite workflow was demonstrated | API validation, persistence, and security |
| Visual reasoning | Image and video input are supported | Correct interpretation and grounded conclusions |
A useful evaluation should include repeatable prompts rather than one impressive demonstration. Ask the model to explain its plan, generate the implementation, identify likely failures, and revise the result after tests. This reveals more than a single polished output.
Preview Evaluation Checklist:
- Confirm the OpenRouter listing still shows Free pricing
- Test one short text-only coding task
- Test one image or video understanding task
- Run generated code through your own tests
- Save a fallback workflow before relying on the model
Compare outputs using the same prompt, context, tools, and acceptance tests. A model that looks impressive in a demo may still require substantial review in your specific workflow.
