Key highlights of Grok Build:
- Massive codebase scale: roughly 2.2k Rust files, 1.35 million lines of code, and 80+ packages.
- Performance relies on a filesystem-native worktree design (CoW worktrees).
- Security is driven by a kernel-native sandbox (Seatbelt / Landlock / seccomp).
- Agent quality depends heavily on infrastructure, not just prompts.
- Supports multiple integrations including TUI, headless, ACP, and MCP.
