DeepRails serves as a platform focused on the reliability of AI, offering research-informed guardrails that are designed to consistently assess, oversee, and rectify the outputs generated by large language models, thereby enabling teams to create dependable AI applications suitable for production environments. Among its key offerings are the Defend API, which provides real-time protection for applications through automated guardrails and correction processes, and the Monitor API, which tracks AI performance by identifying regressions and measuring quality indicators such as correctness, completeness, adherence to instructions and context, alignment with ground truth, and overall safety, alerting teams to potential issues before they impact users. Additionally, DeepRails features a centralized console that empowers users to visualize evaluation results, streamline workflow management, and efficiently set guardrail metrics. Its unique evaluation engine employs a multimodel partitioned strategy to assess AI outputs based on metrics grounded in research, effectively measuring various critical aspects of performance. This comprehensive approach not only enhances the reliability of AI applications but also fosters a proactive stance towards maintaining high standards in AI output quality.
