A risk-based PR approval bot auto-approves the 33% of PRs rated low-risk, which the source says reduced PR lead time by 20-40% compared with all PRs.","company":"Zalando","industry":"E-commerce","aiCapabilities":["Generative AI","Agentic AI"],"technology":["Amazon Bedrock"],"deployment":"Unknown","problemStatement":"With more than 250 engineering teams exploring LLMs at different paces, Zalando needed API-based access to models from several providers, a way to measure adoption, governance and transparency across teams, and a way to protect PR lead time as AI coding increased PR sizes.","solutionApproach":"Zalando's ML platform team deployed a LiteLLM-based API proxy in January 2024 with access to models from OpenAI, AWS Bedrock and Google Vertex, complemented by a chat UI, a CLI built with pydantic-ai, and a centralized agent skill collection. A risk-based PR approval tool rates each PR as low, medium or high rollout risk at creation and auto-approves low-risk ones. Governance runs through an AI section of the Tech Radar.","businessValue":"The source states that 33% of PRs are low-risk and auto-approved by the bot, which in Zalando's case reduced PR lead time by 20-40% compared with all PRs. The proxy runs for 2k MAU on six small pods. Figures are self-reported.","evidence":{"band":"high"},"sourceUrl":"https://engineering.zalando.com/posts/2026/08/agentic-engineering-at-zalando-a-snapshot.html","dates":{"publishedAt":"2026-10-21T05:47:29.847Z","publishedAtSource":"pipeline","updatedAt":"2026-10-21T05:47:29.847Z"},"license":"Open for reading and citing with a link to https://findausecase.com/use-cases/zalando-builds-an-llm-proxy-cli-and-risk-based-pr-approval-bot-for-agentic-engineering-across-250-engineering-teams.
