Grok Bot is now included with SuperGrok Plus, Cursor Pro+, and all Cursor Teams plans.

Grok 4.6 is now available on Vertex AI.

The SDK now supports reference audio for video generation, a generate_audio option, and 1080p resolution. Also added a quality parameter for image generation, an image_generation server-side tool, and automatic tool_call_id assignment when replaying tool outputs via chat.append(response).

Chat history now stays in sync across browser tabs, and an Remove Background action on the post page extracts subjects from images. Also added team invites via organization directory search, voice mode for project conversations, subscription triggers filtered by product and customer, plus assorted fixes across chat, Imagine, Projects, and Automations.

Launchers can now override config settings via GROK_CONFIG and GROK_CONFIG_PATH environment variables, and tool calls no longer fail for the rest of a session if /dev/null is removed. Adds safeguards around automatic worktree reclamation, clearer hook-policy blocking messages, and better Arabic/Persian text reordering in the terminal UI.

Accept xhigh reasoning_effort and add grok-4.6 to ChatModel.

Web search can now be restricted to allowed or excluded domains via [toolset.web_search] in config.toml. A new Follow-up Behavior setting lets queued messages steer immediately, and queued messages no longer auto-submit while still being edited. Includes numerous stability fixes for sessions, subagents, and terminal input handling.

Grok 4.6 builds on Grok 4.5 with a focus on long-running agents and more ambitious interactive and visual work.

Subagent spawning is much faster when you have many sessions in ~/.grok, and TUI rendering now automatically matches high-refresh displays (120 Hz+). /session-info rows are now clickable to copy values, with a copy-all shortcut.

Fixed compaction limits for large sessions with images, and recovered the ability to use sessions after server-rejected images. Worktree copies of large repos no longer inherit unsafe fetch specs or stale shallow grafts, and startup timeout messages now include step details and actionable advice.

Subagent spawning is now bounded with wide fan-outs queuing instead of exhausting file descriptors, /rewind only truncates conversation history (not files) and asks for confirmation by default, and sandbox /** entries now grant the parent directory. Also adds a grok du disk-usage command, read-only tool reporting for safer restricted agents, and fixes for git-status CPU/memory spikes and large-session resume stalls.

Fixed scrambled message order in history search previews and composer layout shifts on paste, plus chat retry cards instead of "Chat not found" errors. Imagine tags return for organizing saved assets, Voice tiles become a Voice Library list, and SuperGrok upgrades to Grok Business are available from grok.com.

MCP tools that return images no longer drop or corrupt large screenshots, and Markdown tables reflow instead of clipping on narrow panes. Also fixes a codebase restore hang, a login skip with an invalid API key, and memory spikes when forking large sessions.

Model picker now updates the status bar and /model menu immediately, even before the first prompt creates a session. Background task completions consume less memory over ACP.
