Meta Introduces AI-Driven Diff Risk Score for Software Development
Meta has developed the Diff Risk Score (DRS), an AI technology that predicts the risk of code changes causing production incidents.
Meta has unveiled the Diff Risk Score (DRS), an AI-powered tool designed to assess the risk associated with code changes in software development. By utilizing a fine-tuned Llama LLM, DRS analyzes code modifications and relevant metadata to generate a risk score. This innovation aims to enhance the reliability of software deployment by predicting the likelihood of incidents, also referred to as SEVs (Severity Events). For more details, visit Meta Engineering.
