xAI Adds Cross-Session Memory to Grok Build Coding Agent

xAI has shipped cross-session memory for Grok Build, its AI-powered coding agent, allowing it to retain context, preferences, and project state across separate sessions. Previously, each session started fresh, requiring users to re-establish context — a significant friction point for complex, multi-day development tasks. With persistent memory, Grok Build can now track decisions, codebase structure, and user preferences over time, moving meaningfully closer to the experience of a persistent AI pair programmer. This is a direct competitive response to similar memory features in GitHub Copilot and Cursor, and raises the bar for what developers expect from coding agents. Teams evaluating agentic coding tools should re-assess Grok Build if session continuity was a previous blocker.
