xAI introduces long-term memory feature for grok build to enhance developer workflow

On September 16, 2026, xAI launched a new memory feature for Grok Build, designed to streamline developers' workflows by retaining project details across sessions. The update allows the AI to carry forward key decisions and facts from previous interactions, reducing the need for repetitive explanations. The memory function operates in the background, automatically extracting valuable information such as coding habits and architectural rationale without disrupting ongoing tasks. It filters out temporary data and confidential information, ensuring only relevant content is stored. The system organizes notes by project and includes user preferences to avoid information overload. Developers can use the /dream command to manually consolidate notes into structured Markdown files, while the /memory command provides a read-only interface to review stored data. The feature is now available for all new sessions, with background memory capture activated after the first interaction. This update aims to improve efficiency by ensuring context is preserved, even when instructions conflict with historical data.
