Grok Build adds Memory for project knowledge across coding sessions

A September 16, 2026 post says SpaceXAI introduced Memory in Grok Build, available for new sessions. It describes notes captured in the background after each completed turn and relevant memories read when users return to a project. According to the post, /dream automatically organizes notes into topic files, while /memory lets users browse and preview saved memories. The feature is described as leaving out secrets, temporary task status and information already covered in project files. Current instructions take priority over saved memories.
