With the rapid advancement of Artificial Intelligence (AI) technology, effectively applying these technologies in large-scale environments has become a significant challenge. Recently, Arthur launched Arthur Engine, the first open-source, real-time AI evaluation engine designed to help teams monitor, debug, and improve generative AI and traditional machine learning (ML) models. Its key feature is its independence from third-party tools, ensuring data privacy and security, all while being completely free.
In 2025, the importance of real-time AI evaluation is increasingly evident. As AI technology becomes more widely adopted, associated risks are also rising. For instance, surveys reveal that 8.5% of employee prompts contain sensitive data, models can degrade without continuous monitoring, and slow iteration cycles can lead to decreased model performance. Arthur Engine addresses these issues by providing immediate visibility, real-time safeguards, and online model optimization, ensuring the healthy development of AI technology.
Arthur Engine offers significant advantages over traditional AI monitoring tools. The engine runs locally, safeguarding data sovereignty and eliminating compliance risks. Its core functionalities include real-time AI evaluation for instant fault detection; proactive safeguards for real-time intervention to prevent erroneous model outputs; customizable evaluation metrics allowing users to adapt to specific AI application scenarios; and support for all models, including open-weight models like GPT, Claude, and Gemini, as well as traditional machine learning models.
Cherie Xu, Head of Technology at Arthur, stated: “By open-sourcing Arthur Engine, we're making AI trust and safety tools readily accessible to all developers, empowering them to protect AI systems with highly customizable, high-performance monitoring tools.” Arthur Engine is also part of Arthur's broader AI performance monitoring suite, designed to help organizations verify AI outputs in real-time, promptly identify performance fluctuations, and ensure compliance and explainability.
This open-source release marks a new standard for AI transparency, security, and performance monitoring. More information about Arthur Engine can be found on GitHub, and users can also join the waiting list for the Arthur platform. AI is constantly changing the world, and our goal is to ensure it does so responsibly.
