Grok Build

Key features

• Parallel subagents in isolated sessions Parallel subagents in isolated sessions: spawn several agents at once, each working in its own session and ordering, so independent tasks proceed concurrently instead of queuing behind one another.[1]

• Goal mode for gated autonomous runs Goal mode for gated autonomous runs: a /goal command lets the agent pursue an objective across multiple steps, with approval modes and workspace rules deciding how far it may act before asking.[1]

• Reasoning-effort control Reasoning-effort control: a reasoning_effort setting scales how hard the model thinks per task, trading latency and cost against depth on work that needs it.[1]

• Text and image input Text and image input: prompts accept screenshots, mockups, and diagrams alongside text, so visual context such as a design or an error screenshot enters the task directly.[1]

• MCP servers and Agent Client Protocol support MCP servers and Agent Client Protocol support: wire in external tools through Model Context Protocol servers, and embed or drive the agent from editors and scripts through ACP, including headless non-interactive use.[1]

• IDE extensions with session sync IDE extensions with session sync: VS Code, Cursor, and Windsurf extensions mirror the terminal session, letting developers move between editor and shell without losing state.[1]

• Cross-session memory with portable skills Cross-session memory with portable skills: memory carries decisions across sessions, and reusable skills can be imported, exported, edited, and shared across projects.[1]

• Subscription or API-key auth with metered billing Subscription or API-key auth with metered billing: sign in with an xAI login backed by a SuperGrok plan, or bring an API key from a free console signup; steady-state inference bills through the subscription or per-request compute rates.[1][2]

Who will love it

• Terminal-first developers running parallel work: if your normal loop is shell, editor, and diff, parallel subagents with isolated sessions map directly onto how you already juggle tasks.[1]

• Teams already committed to xAI billing: where a SuperGrok subscription or xAI API spend is already approved, the native CLI removes a vendor without adding a new one.[1][2]

• Automation-minded shops: headless scripting, ACP embedding, and portable skills give scripted and repeated workflows a stable surface to build on.[1]

Who should avoid it

• Teams that need model choice: inference is xAI-only; if you want to swap providers, run local models, or benchmark backends, an open-backend agent fits better.[1][2]

• Budget-sensitive adopters without a paid tier: the client is free but inert without a subscription or funded API key, and beta free usage is time-limited rather than a permanent tier.[1][2]

• Organizations needing SSO and support guarantees: enterprise SSO sits behind a gated agreement, no support plan or SLA is documented, and the repository accepts no external contributions, so regulated or support-dependent rollouts carry unknowns.[1][2]
