Diff Risk Score: AI-driven risk-aware software development

This post introduces Diff Risk Score (DRS), an AI-powered technology built on a fine-tuned Llama LLM that predicts the likelihood of code changes causing production incidents (SEVs). It highlights DRS's impact on enabling code unfreezes during sensitive periods, leading to significant productivity gains and reduced engineering time spent on incident mitigation. The post also outlines future directions for risk awareness in software development, including expanding to configuration change risk, automating risk mitigation, and improving natural language explanations for risk-aware technologies.
