500k context window
SpaceXAIText and image inputs with text-only output and no text output limit.
Reasoning effort
SpaceXAIConfigurable reasoning: low, medium, high (default), and xhigh.
API pricing
SpaceXAI$2 / $0.50 / $6 per 1M tokens (input / cached / output) below 200k prompt tokens; $4 / $1 / $12 above. Grok 4.7 Fast is billed at twice those rates in Cursor and Grok Build.
Responses API reasoning payload
SpaceXAIOn the Responses API, grok-4.7 always returns reasoning.encrypted_content even when include omits it.
Where it runs
SpaceXAIxAI API (grok-4.7), US regional endpoint, Cursor, and Grok Build (Grok 4.7 Fast).
Own cloud computer
SpaceXAIEach Bot runs on a persistent cloud VM with a browser, filesystem, and terminal. All Bots on an account share that user-scoped computer (files, browser sessions, logins), with a separate screen per Bot.
Always-on runtime
SpaceXAIKeep working 24/7 in the cloud after the client is closed.
Colleague messaging
SpaceXAIMessage a bot like a teammate. Bots remember conversations, share context in threads, and can coordinate in group chat.
Skills
SpaceXAIA skill is a reusable set of instructions for how to do a task. Skills are available across Bots. Teach a task can record a browser workflow (up to ten minutes) into a draft skill when that control is visible.
Routines
SpaceXAIA routine tells one Bot when to run a workflow — on a schedule or, where supported, after an event. Background routines can run while the laptop is closed. A Bot can own up to 50 routines.
Supported platforms
SpaceXAIDesktop app on macOS (Apple silicon and Intel) and Windows (x64 and Arm64); mobile app on iPhone (iOS 18+) and Android (Android 9+). Linux desktop and iPad are not supported.
Approvals
SpaceXAIBots only pull you in for judgment calls. They follow up on dropped threads and nudge stalled handoffs.
Connectors
SpaceXAISign into the tools you already use and work across apps and inboxes, including platforms with no clean API or MCP.
Plan mode
SpaceXAIThe agent explores and drafts a plan before edits. Only the session plan file may be edited until you approve; bash is not gated. Auto and always-approve do not skip plan review. Enter with /plan or Shift+Tab; the agent can enter plan mode on its own. Reopen with /view-plan.
Auto and always-approve
SpaceXAIAsk (default) prompts for anything not already allowed. Auto uses a classifier to auto-approve safe tools. Always-approve skips permission prompts; deny rules and PreToolUse hooks still apply. Shift+Tab cycles Normal → Plan → Auto → Always-approve. Allow/deny rules in [permission] or --allow/--deny; deny wins.
Headless and scripting
SpaceXAIRun without the TUI via grok -p. Optional --output-format streaming-json for scripts, automations, or other apps.
Agent Client Protocol
SpaceXAIUse Grok Build through the Agent Client Protocol (ACP) in other apps.
Subagents
SpaceXAIIndependent child sessions with their own context; they return a summary to the parent. Built-in types: general-purpose, explore (read/list/search only), and plan (no shell, no edits). Add types under .grok/agents/ or ~/.grok/agents/. Personas are behavioral overlays via /personas.
Skills
SpaceXAIReusable folders with markdown, scripts, and resources (SKILL.md). Discovered from ./.grok/skills/, ~/.grok/skills/, plugin skills/, and [skills] paths. User-invocable skills appear as /<skill-name>. Capture a session as a skill with /skillify.
Plugins
SpaceXAIPlugins add skills, agents, hooks, MCP servers, and LSP servers from ./.grok/plugins/, ~/.grok/plugins/, marketplace installs, [plugins] paths, or --plugin-dir. The TUI extensions modal opens from /plugins, /hooks, /skills, or /mcps.
Marketplaces
SpaceXAITUI Marketplace tab installs plugins from [[marketplace.sources]] in ~/.grok/config.toml and ~/.grok/plugins/known_marketplaces.json.
Claude Code compatibility
SpaceXAIReads Claude Code marketplaces, plugins, skills, MCPs, agents, hooks, and instruction files (CLAUDE.md, Claude.md, CLAUDE.local.md, .claude/rules/) alongside .grok/ with no extra setup.
Hooks
SpaceXAIJSON hooks (command or HTTP) on lifecycle events. PreToolUse is the only blocking event (explicit deny, else fail-open). Personal ~/.grok/hooks/*.json; project .grok/hooks/*.json needs /hooks-trust or --trust. Also reads Claude Code and Cursor hook files.
MCP servers
SpaceXAIMCP servers expose external tools as <server>__<tool>. Add with grok mcp add (stdio or HTTP/OAuth). Also declared in ~/.grok/config.toml or project --scope. Loads ~/.claude.json, .cursor/mcp.json, and .mcp.json unless compat is disabled. /mcps in the TUI.
AGENTS.md
SpaceXAILoads AGENTS.md, Agents.md, AGENT.md, CLAUDE.md, and *.md in .grok/rules/ (plus .claude/rules/ and .cursor/rules/) from repo root down to cwd; deeper files win. --rules appends session-only text. grok inspect lists loaded files.
Web and mobile
SpaceXAIGrok Build is available beyond the terminal — web and mobile surfaces announced Aug 19, 2026.
Release channels
SpaceXAIInstaller respects GROK_CHANNEL=stable|alpha|enterprise (default stable). The welcome screen shows the active channel. Failed channel updates suggest the matching reinstall command. Persist the choice in ~/.grok/config.toml under [cli] channel.
Sessions
SpaceXAIEvery conversation is saved under ~/.grok/sessions/. Resume with /resume, grok --resume, or grok -c. /fork branches a peer session; /rewind restores files and truncates the conversation. grok sessions list/search/delete and grok export manage them.
Worktrees
SpaceXAIIsolated git checkouts under ~/.grok/worktrees/<repo>/<name> so parallel agents do not overwrite each other. Start with grok -w, /fork --worktree, or Ctrl+W on the dashboard. Persist until grok worktree rm or gc.
Sandbox
SpaceXAILimits what an approved tool call can read, write, and reach on the network (Landlock on Linux, Seatbelt on macOS). Off by default. Profiles: off, workspace, devbox, read-only, strict. Enable with grok --sandbox, [sandbox] profile, or GROK_SANDBOX.
Agent Dashboard
SpaceXAIFullscreen overview of every session (needs input, working, idle, completed, failed). Open with Ctrl+\, /dashboard, or grok dashboard. Reply or answer permission prompts inline; Ctrl+W starts new agents in a worktree.
Background tasks
SpaceXAIRun commands, subagents, and monitors while the conversation continues (/tasks, Ctrl+G). /loop repeats a prompt on an interval (max 50, expire after 7 days). Monitors notify on each script line. Ctrl+; or /queue lists prompts queued behind the running turn.
Theming
SpaceXAITUI themes via /theme or [ui] theme in ~/.grok/config.toml. Built-ins include GrokNight (default), GrokDay, TokyoNight, RosePineMoon, and OscuraMidnight. theme = auto follows OS light/dark.
Imagine Image 2.0

Subscriptions
CursorMonitor PRs, watch a Slack thread, or run scheduled tasks. Agents wake on events and can auto-subscribe to PRs they create.
/goal and /loop
CursorAssign a long-lived objective (e.g. fix flaky tests and make CI green). Pair with /loop for recurring check-ins.
Subagents run on isolated VMs with clean project copies. Swarm them for independent tests.
Custom modes
CursorPin skills as always-on modes so agents stay focused. Select from the / menu.
Steering
CursorSend a follow-up without interrupting the current turn. Press return twice or Send now.
Builds
CursorReady-to-use copies of the dev environment. Agents boot ~3× faster to first token; included with Cloud Agents.
Conversation hooks
CursorObserve and control prompts, responses, thinking, subagents, compaction, and turn completion.
Start from scratch
CursorCloud Agents can start without a connected GitHub or other SCM. Cursor creates an Origin repo in the background; save with Create repo when ready.
Live preview
CursorPort-forwards the cloud agent environment to the browser for preview and design mode.
Vercel publish
CursorConnect a Vercel account and publish the agent build to a live URL.
Self-hosted machines
CursorRun cloud agents on machines in your network. My Machines connects a laptop or VM; team pools scale workers on demand with hibernate and restore. Integrates with AWS Lambda, Coder, Cloudflare, Daytona, Modal, Namespace, Vercel, and E2B. Self-hosted workers support computer use on Linux and Mac.
Projects
CursorLong-running work with a coordinator agent that plans and delegates to implementing agents. Shared context files sync across cloud and local machines; runs on a cloud computer when the laptop is closed.
Rollouts
CursorChange monitor on every pull request: writes a monitoring plan, tracks deploys per environment, and reports verified healthy, regression detected, or inconclusive. Connects Origin or GitHub, CD deploy events, and telemetry (Datadog and others).
Security Review
CursorPosts one review comment per pull request reporting exploitable bugs (injection, auth bypass, secrets in source, SSRF, unsafe deserialization, vulnerable dependencies). Team rules enforce codebase-specific policies. Draft PRs are skipped.
Agent SDK
CursorAgents as code: instructions.md, tools/, skills/, MCP connections, and channels. `agent-sdk dev` runs locally; `agent-sdk deploy` hosts on Cursor. Evals and `agent-sdk github replay` test PR-driven bots.
Live apps
CursorCloud agents scaffold web apps, provision Postgres and Cursor SSO auth, run security review, and publish to a chosen domain for team or public sharing.
