OpenRouter has unveiled a new AI model called Ox Alpha, offering free access with impressive capabilities. The stealth model has quickly caught attention from developers for its power and flexibility in coding, long-running AI agents, and production workloads. You can start using it today with no cost for input or output during a one-week preview.
What Is Ox Alpha?
Ox Alpha is a cutting-edge AI model that supports text, image, and video input. It has a 1,048,576-token context window and allows for tool calling. The model is available through the same API many developers already use, making it easy to integrate into your workflow. You can also find it in OpenCode, an open-source coding agent, where it’s nearly unlimited and free for a short period.
Key Features of Ox Alpha
- 1,048,576-token context window
- Supports text, image, and video input
- Free access during a one-week preview period
- Tool calling capability
Performance and Testing Results
Ox Alpha has a 4.45% tool-call error rate and processes about 50 tokens per second with a median latency of 2.02 seconds. Developers have tested it, and one independent test showed it scoring 80% on DeepSWE, outperforming models like Fable and GPT-5.6 Sol. The model’s performance has impressed many in the tech community.
Data Privacy and Security
OpenRouter says it doesn’t use prompts or completions for training during this release. However, a separate service called OpenCode claims to offer “Zero Data Retention” for Ox Alpha traffic. The distinction highlights the growing attention around data practices in AI. You can use Ox Alpha with confidence, knowing your data is protected during the preview period.
Why Ox Alpha Matters
Ox Alpha matters because it’s free and powerful. Developers can use it without any cost, making it an attractive option for testing and integrating into projects. The model also appears in OpenCode, where it’s been made nearly unlimited for a short period. You can take advantage of this opportunity to explore what Ox Alpha can do for your work.
Who Built Ox Alpha?
The origin of Ox Alpha remains a mystery. OpenRouter says it’s a third-party model, and the provider has opted to stay anonymous during the preview. Some early speculation pointed toward Zhipu’s GLM-5.3 model, but that hasn’t been confirmed. The lack of a clear origin has sparked curiosity and debate in the developer community.
OpenRouter’s History with Stealth Models
This isn’t the first time OpenRouter has released a stealth model. The platform has a history of launching models under codenames like Hunter Alpha and Healer Alpha, often from unknown providers. These models typically offer free access during a preview to drive adoption and feedback. You might find Ox Alpha part of this ongoing trend.
What’s Next for Ox Alpha?
The mystery around Ox Alpha isn’t new, but it has raised questions about the competitive landscape in AI. The model’s sudden appearance has sparked excitement, with developers eager to see what it can do. The answers about who built Ox Alpha might not come soon, but the excitement it’s generating is clear. You can keep an eye on future updates as more details emerge.
