Meta Introduces Diff Risk Score for Software Development
Meta has developed the Diff Risk Score (DRS), an AI tool that predicts the risk of code changes causing production incidents.
Meta has unveiled the Diff Risk Score (DRS), an AI-driven technology designed to assess the risk associated with code changes. DRS utilizes a fine-tuned Llama LLM to evaluate code alterations and their metadata, generating a risk score that indicates the likelihood of a production incident, referred to as a SEV. This innovation aims to enhance software development practices by providing developers with insights into potential risks before deployment. For more details, visit Meta’s Engineering Blog.
