Worked on the MicrosoftDocs/azure-ai-docs repository to deliver a comprehensive clarification of the Model Availability and Retirement Policy for Generally Available (GA) models. Focused on updating model-retirements.md using Markdown, the work established clear timelines by defining a minimum 12-month GA window, with an additional six months for existing customers and a 12-month window for new customers accessing older versions. This documentation effort leveraged skills in policy writing, Git version control, and cross-team collaboration to align lifecycle policies across Azure AI documentation. The update aimed to improve customer planning, reduce support escalations, and support migration strategies by clarifying model availability expectations.
