Grok Build adds cross‑session memory to persist project facts and conventions
xAI announced a new long‑term memory feature for Grok Build that records durable project facts, coding conventions and decisions as markdown notes and reads them back in later sessions. The feature runs in the background, stores notes per project plus a global scope, and exposes /memory, /dream and /remember commands to browse and manage stored notes. This aims to reduce repetitive onboarding in new Grok Build sessions and is available now for new sessions.

Despite Musk's posts naming Grok 4.8 and its parameter count, xAI's public documentation and product pages still list grok-4.6 as the newest available model and contain no grok-4.8 entry, pricing, or model card. That means developers have no verified API identifier, context-window details, or pricing to use for planning.
