Grok Build news: @spacexai is back with a banger! Some of the best changes in 0.2.105: • Grok 4.5 is now the default model, with high, medium, and low reasoning effort • /btw now works inside grok --minimal • New /summarize command for instant session summaries • Local shell tools now inherit your normal environment variables, aliases, and functions • Improved long-session compaction • Global rules are now discovered correctly • Smoother scrolling under load and on slow connections Plus a long list of bug fixes. Another seriously strong update.

Just press Ctrl + Space in Grok Build and start talking Grok's Speech-to-Text is incredibly accurate, transcribing your prompts in real time as you speak It makes interacting with your coding agents feel completely natural Instead of pausing to type every instruction, you can simply think out loud while Grok keeps up with your ideas Once you start using voice in Grok Build, it's surprisingly hard to go back to typing everything

Elon Musk said: “I want to live long enough to see a mass driver on the Moon, because that is going to be incredibly epic” This is not just about building infrastructure on the Moon. It is about building one of the most ambitious futures humanity has ever imagined A lunar mass driver will unlock an entirely new space economy, move enormous amounts of cargo beyond the Moon and open the solar system to human expansion A future far more exciting than anything humanity has experienced before x.com/XFreeze/status/2057353…

Grok Build now has /timeline command to Toggle the timeline sidebar

I’m running Fable, K3, 5.6 and 4.5 like 10 hours a day and they are all sick. At work, at home. I have subscriptions for many of them at both locations. But you know which model legit doesn’t get enough hype? GROK. I’m so serious. Even on 𝕏 it doesn’t get enough hype cause we assume oh yeah it’s Elon’s network of course they are gonna hype grok. But I don’t care about benchmarks. It absolutely crushes in usefulness and im quickly using it more and more. It gets the job done well, and fast, and it doesn't spend all day thinking about nothing. But its not just fast and cheap. Sometimes it WORKS BETTER than 5.6 or even Fable. Check this. I told Grok and Codex to help design a level that I could dynamically spawn some quest monsters and players on using the level tools available for my game. Sol on max settings took forever to put out garbage and Grok's level was pretty sick right away. I have many other dramatic cases of Grok outperforming so called frontier models on genuinely useful tasks. I can’t wait for the 2 parameter model.

you should give Grok 4.5 a try

you awake from a deep trance, step away from the phone to see your friends & family

The FrontierCode leaderboard is now live: a dedicated page that tracks which models are writing code you’d actually merge. All scores — including Grok 4.5 and Inkling — are available, along with full methodology and sample tasks.

Grok 4.5’s efficiency is ridiculous On Artificial Analysis, it costs just $0.31 per Intelligence Index task while delivering frontier intelligence For comparison: • Claude Fable 5 (max): $2.75 • Claude Opus 4.8 (max): $1.80 • GPT-5.6 Sol (max): $1.04 • Kimi K3: $0.95 • Grok 4.5: just $0.31 That makes Grok 4.5 roughly: • Nearly 9× cheaper than Claude Fable 5 • Nearly 6× cheaper than Claude Opus 4.8 • 3× cheaper per task than Kimi K3 • 3.4× cheaper than GPT-5.6 Sol On FrontierSWE, Grok 4.5 also used nearly 6× fewer total tokens per task than Fable 5 while still ranking near the very top SpaceXAI has figured out how to deliver top-tier intelligence with extraordinary token efficiency At this level of performance, no other frontier model is operating in the same cost-efficiency league Grok 4.5 does not brute-force every problem with endless tokens and compute It makes every token and every dollar work harder

How many of you have heard of Ilias Kasidiaris? The former Greek MP and politician remains imprisoned in Greece, due to one of the most controversial cases in the EU. He’s serving time from the Golden Dawn convictions, but a recent judicial decision has drawn heavy criticism: His June 2025 release request was denied 2-1, against the Prosecutor’s recommendation, partly because he maintains an active X account (@IliasKasidiaris), with help from supporters to comment on politics. “The applicant… maintains a personal account on… X… expressing his views on current political and social affairs,” the court said. They will therefore keep him imprisoned despite good conduct and significant time served. This sets a dangerous precedent for political speech. How does it differ from cases Elon Musk has criticized in the UK?

orbit ten degrees and it is a painted slab with four chrome rods hovering nearby • the playfield z-fights with the glass – hard black banding across the whole field as soon as you pull the camera back a note on the pinball, in fairness to kimi: nobody passed it. every model shipped broken ball physics and controls you cannot trust. it is the hardest prompt we have run and the whole field failed it, each in its own way kimi k3 reasons better than anything else here and it shows exactly where reasoning pays – physics constants, sequences, edge cases, traps the others walked into follow @thehypedotnews for 24/7 ai news, analysis and breakdowns

We are beings of light, and Grok reveals this light.✨

Grok Build just received another major update, introducing powerful conversation navigation, enhanced enterprise controls, smarter terminal workflows, and extensive reliability improvements Release Notes: v0.2.102 — 2026-07-16 Breaking Changes: • --minimal and --fullscreen flags now apply only to the current session. Features: • New /jump slash command lets you quickly jump to any previous turn in the conversation. • New /timeline sidebar shows a clickable tick rail for fast navigation between conversation turns. • grok login now requests Grok Projects scopes so workspace listing works after consent. • Permission mode can now be set fleet-wide via remote config when no local setting exists. • Edit tool output has a setting to show a compact one-line summary instead of always-expanded diffs. • Tab completion in !bash mode now works like a normal terminal (prefix fill, dropdown, directory drill-down). • Enterprise deployments can now disable voice dictation via requirements.toml so /voice and Ctrl+Space are hidden for everyone. • User prompts now appear bold only in --minimal mode; fullscreen keeps normal weight. • grok plugin install now accepts a marketplace's registered name as a qualifier. • Consecutive edits to the same file now collapse into a single scrollback row when collapsed edit blocks are enabled. • Local sessions now inherit your shell environment variables and keep the current directory across commands. Bug Fixes: • Login and re-login no longer stack multiple device-code polls or leave stale flows running. • Background task tools now render with correct icons and titles instead of the generic MCP wrench. • Task tool now correctly validates and displays allowed model slugs for subagents. • Rewind now correctly handles bash transcripts, permission follow-ups, and sessions that mix old and new prompt markers. • Re-login during a session now immediately uses the new token instead of requiring a new session. • Terminal commands using globs now behave the same on zsh as on bash and no longer fail with shell errors. • Installer no longer replaces stowed shell configuration symlinks with plain files on upgrade. • Voice transcription now works with enterprise API bases and API-key authentication. • Fixed crashes on some network-mounted home directories by using a safer SQLite journal mode. • Home and End keys now move to the ends of the current wrapped line in the prompt. • Arrow keys and Esc now work correctly inside viewers opened from the dashboard. • Warns at startup when user and project sandbox profiles define the same name differently. • Billing upgrade links now show the full URL in the transcript (and copy it) when a browser cannot be opened. • Fixed Ctrl+Y yank no longer working after sending a prompt. • No longer shows permission prompts seconds after a turn was cancelled with Esc or Ctrl+C. • Page Up and Page Down now move the highlighted entry to the top or bottom of the visible scrollback area. • Conflicting project and user sandbox profiles now show a clear warning on the welcome screen. • OAuth login URLs no longer contain duplicate referrer parameters. • File links in official VS Code Remote-SSH terminals now use VS Code's native path handling. • Minimal mode now shows the folder-trust prompt after sign-in when required. • Skills whose names collide with built-in slash commands are now reachable via qualified names. • Fixed background task tracking when using grok -p --no-wait-for-background so tasks are properly reaped on exit. • Rate limit errors (429) now show specific server messages (capacity, team limits, free-usage) instead of generic upgrade prompts, with correct copy based on auth type. • /copy slash command is now available in minimal mode. Performance: • Improved recap and compaction behavior.
