Two Copilot changes shipped May 15: Grok Code Fast 1 was deprecated across all Copilot experiences (chat, inline edits, completions) — admins should switch to GPT-5 mini or Claude Haiku 4.5. Separately, Copilot Memory now supports user-level preferences for Pro and Pro+ subscribers, allowing stated or inferred preferences (commit message style, PR structure, communication tone) to follow users across all repositories and agents; manageable in personal Copilot Memory settings.

Why it matters

User-level persistent memory across repos is a meaningful shift toward truly personalized coding assistants. Deprecating Grok Code Fast 1 suggests xAI's early Copilot model integration has been superseded and signals continued portfolio churn in the multi-model Copilot marketplace.

Importance: 2/5

Cross-repo user memory is a notable personalization feature; model deprecation requires admin action
