Grok Build, xAI's CLI-based coding agent, has launched a new /remember command to address the cold start problem in AI-assisted development. Released as part of the v0.2.3 update on May 27, 2026, this feature allows developers to save notes and project context that persist across sessions, eliminating the need to repeatedly explain project details to the AI assistant. The update also includes a side-by-side preview feature, always-approve permissions, improved image processing, and JetBrains terminal support. The introduction of the /remember command is a strategic move by xAI to enhance developer control over retained information, crucial for managing multiple projects with varying conventions. This update comes just ten days after Grok Build's beta launch, highlighting xAI's rapid iteration pace. However, as Grok Build is still in beta, the effectiveness of the /remember feature in handling complex real-world projects remains to be seen.
