grok worktree rm without -f now refuses to delete worktrees that are in use or have unsaved changes and exits with an error, and long sessions stay connected when the conversation exceeds 4 MiB. The release also retries stalled model calls and Chat Completions streams that end without a finish reason, prevents concurrent settings edits from dropping config.toml entries, and adds a timestamps setting plus TSV/CSV/Markdown table export.

Grok 4.7, described as the most capable model for coding and knowledge work, now powers Expert mode on grok.com and Fast mode for paid subscribers, and Grok Bot is available on grok.com to SuperGrok Plus and SuperGrok Heavy subscribers with bots in the sidebar's Bots section. The release also adds bot organization with sidebar sections and approval requests, connector reconnect for expired sign-ins, Imagine upload cancel and video mode frame selection, plus a Safari sign-in fix.

Cancelling one tool call no longer terminates commands started by other parallel calls, and Ask rules for WebSearch and WebFetch now show a prompt instead of running on their own. The read_file, search_replace, and grep tools handle large, special, and binary files more reliably with clearer errors, and /rewind now lists only prompts you typed.

Web searches, fetches, and image generation now follow the prompt_policy setting and rule decisions before prompting, and "Allow once" on a permission card applies only to the next shell command. Hook permission prompts now appear in every approval mode, and pkill -f and pgrep -f are rejected earlier when the pattern would kill their own shell wrapper.

Switching models from the agent now updates the displayed model list and context window, and clicking the Goal chip opens the goal panel even when workflow runs are present. Error messages on the home and login screens wrap on narrow terminals, and sessions in a repository with an .envrc file start faster.

grok-voice-transcribe-1.0 is deprecated and reaches end of life on October 2, 2026. Until then all requests to that slug route to grok-voice-transcribe-2.0 at the same price, with higher accuracy.

Permission rules with relative paths now apply when the working directory contains symlinks, and video cards no longer get stuck extracting posters without ffmpeg. Also faster session startup when loading skills from large directories, plus fixes to MCP server source reporting, client rule preservation on system prompt rebuilds, and slow list_dir subtree counts on network filesystems.

Custom agents from plugins or config can now be chosen directly with spawn_subagent, and MCP servers can use a token file that is re-read on every request so rotating credentials stay fresh. Also added colored notice banners above the prompt for selected models and a "Waiting for N subagents…" status when the parent turn is blocked.

xAI launched Team Bots, Grok Bots that work and learn alongside teams with access to files, instructions, and skills, plugins for Salesforce, Notion, and GitHub, secure third-party API credentials, and memories that retain learnings over time. Each person's conversations stay private while the Bot draws on shared team skills, and Team Bots can collaborate in Slack under their own handle.

A new /context-window slash command lets you pick a context window size for the current session when the model offers choices, and /model selection now offers context window choices before effort level. Pasting on Windows no longer crashes from overlapping clipboard operations, and parallel tool calls that edit the same file now run in sequence.

MCP tool prompts now appear correctly in minimal mode, and users are notified when a prompt goes unanswered.

New grok worktree create command creates a managed worktree without launching an interactive session, and plugin hooks now run on a fresh session without an explicit reload. Fixed bracketed pastes attaching leftover images, grok -p not exiting cleanly on interrupt, inline images appearing blank after repaint, and Ctrl+C twice while writing a plan comment getting stuck.

Grok Bot on SuperGrok Heavy can now be called with voice options and language settings, with voice chat transcripts and Bot browsing and import. Imagine gains a Loop tile for video start and end points, and a voice mode bug that left the mic silent after network changes is fixed.

Video generation now accepts a last frame and keyframes. The rest of the release is changelog and release-workflow housekeeping.
