Wayfair: Gemini-powered AI CI/CD intelligence for faster build-failure remediation

Wayfair built a GenAI-powered CI/CD intelligence system to reduce developer toil caused by post-commit build failures. The system combines Google Cloud's Gemini model with a custom RAG pipeline over Buildkite logs, MCP metadata, and historical failure data to generate explanations and fix recommendations in Slack and inside developer IDEs. The solution is live in production and used by about 70% of Wayfair developers.
