OpenRouterAI has added a new large language model, Horizon Beta, to its platform, positioning the system as an upgraded successor to its existing Horizon Alpha model. The company describes the release as a “stealth” deployment, suggesting the model is available immediately for developers seeking an alternative option for code-generation and general language tasks. While technical specifications were not disclosed, OpenRouterAI says Horizon Beta delivers improved performance over Horizon Alpha. The model can be accessed through the OpenRouter marketplace and integrated into third-party applications, including the Anycoder mobile interface for on-device coding.
