Grok Build no longer starts projects from scratch: the next session reads past decisions
On September 16, 2026, xAI added cross-session memory to Grok Build. After each completed turn, the agent writes conventions, decisions and project facts to markdown files and reads them when returning to a project. In version 1.0.34 from the same date, Memory is marked as generally available.

Grok Build now has memory across sessions. It now remembers your code project between sessions: commands, conventions, decisions, and project facts. After every turn, it writes project conventions and decisions to markdown. The next session reads them before touching related code. Your coding agent finally stops starting from scratch. /memory browse /dream consolidate Enable it with GROK_MEMORY=1 /new -> work for one turn -> check /memory -> run /dream once you have accumulated plenty of notes.

A new Grok Build session started without the conventions and decisions from the previous one. Now Grok Build saves them after every turn and reads them before modifying related code.
What it means in practice. Project memory stores conventions, decisions, and project facts separately from global user preferences. The `/memory` and `/mem` commands display and manage notes, while `/dream` consolidates new observations into topical markdown files.
Enablement. Install Grok Build with `curl -fsSL https://x.ai/cli/install.sh | bash`, then run `grok` in the project directory. `GROK_MEMORY=1` enables Memory, while xAI recommends `[memory_v2] enabled = true` in `~/.grok/config.toml` for a persistent configuration; use `--experimental-memory` for a single run and `--no-memory` to disable it. After `/new`, notes begin to be created after the first completed turn.
Next, `/dream` will consolidate accumulated observations into topical markdown files for future sessions.
