This is the easiest way to get started with Grok Build. Just go to grok.com/?mode=build, no scripts or download needed.

India needs @Starlink • 11,256 of India’s listed villages still had no 4G coverage as of May 2026. • India had 1.093 billion internet subscriptions in March 2026, but only 440.87 million were rural. Rural subscription density was 48.31 per 100 people, compared with 126.80 in urban India. • BharatNet has laid more than 850,000 route-km of fibre and made about 221,000 Gram Panchayats service-ready. Yet its Points of Presence were reported operational at only 80,472 GPs as of June 2026. The government itself says the remaining mobile gaps are caused by difficult terrain, low commercial viability and infrastructure constraints. This is exactly where Starlink can help by reaching remote villages, mountains, islands and disaster-hit areas. Direct-to-device connectivity could also help phones stay connected beyond tower coverage. The Indian government should complete the remaining clearances, allocate spectrum and clear Starlink for commercial launch ASAP. India has already waited far too long.

Two really good reasons to buy the Model Y 1. It's fun to drive 2. FSD is the real deal

Grok Build 1.0.8 is out. @spacexai keeps improving the agent workflow, with this release focused heavily on subagents, workflows, and smoother multitasking. Most important changes: • Concurrent subagents now start much faster and no longer freeze the parent session • Opening many subagents at once no longer freezes the UI while loading history • Follow-up messages are sent immediately even while a subagent/task is running • Ctrl+S now stashes your current prompt draft so you can switch tasks and restore it later • /workflow now autocompletes saved workflows and only shows valid actions • MCP servers can request form input or URL consent through the normal question popup • Workflow agent rows now show current context usage instead of cumulative token counts Also included: clearer errors for hallucinated tool calls, status-line fixes, and improved folder downloads.

Grok 4.6 just took the #1 spot on CursorBench 3.2.....and the efficiency is insane Here's the cost comparison: • Grok 4.6 Extra High — 70.8% | $2.81/task • Fable 5 Max — 70.5% | $17.32/task • Opus 5 Max — 70.0% | $8.23/task • GPT-5.6 Sol Max — 67.2% | $5.69/task Grok achieved the highest score while costing roughly 6X less than Fable 5 Max and nearly 3X less than Opus 5 Max per task That’s what makes Grok so powerful for agents Top-tier intelligence is great.....but top-tier intelligence that can keep working across long coding tasks without burning ridiculous amounts of compute is even better Grok’s agentic coding efficiency is insane

We're making Grok Bot more widely available. All SuperGrok Plus, Cursor Pro+, and Cursor Teams subscribers now have access. We're also offering a free trial with limited usage for all other users.

One of the best things I gave my Grok Bot... Was its own email address. Now it can: → Send emails → Receive replies → Verify accounts → Sign up for websites → Use email inside its own workflows Takes 2 minutes... Now it can do a LOT more without me.

Grok Bot might be the first tool that lets one non-technical person run an entire business with a team of AI agents. My friend Billy runs his whole newsletter business on Grok Bot agents, and I think we're about to see 100,000+ businesses like his. BEST PRACTICES: 1. The agents run on a shared cloud computer, so running your newsletter, your X, and your receipts all in one place creates context bloat and burns tokens fast. One mission per setup. 2. Start with a Chief of Staff. Give it access to your existing docs (Notion, Slack, Gmail), have it audit the business, then tell you the top three agents to build first to drive revenue. 3. Perfect a task with the Chief of Staff before spinning up a new agent. Have it do the outbound sales once, review it, and only then say "now build a bot that does exactly that." You earn each new hire by proving the task works first. 4. Constraints are the feature. You get a limited number of agents, one thread per bot, like DMs with a teammate. It forces you to stay mission-oriented instead of spinning up a bot for every random idea. 5. You make the decisions, not the agent. Billy's team spent three weeks unable to pick where content should live. At some point you say "we're doing Notion, no more tinkering" and move on. 6. Run week one with no new agents. Build the team, learn to fly the plane, just execute. Week three is when you find the real gaps and expand, someone to man the inbox, someone for the Shopify shop. 7. Then add routines so it works while you sleep. Ask your Chief of Staff what recurring jobs would move the business forward overnight, and it builds the automations that run without you. Thanks to @billyjhowell for sharing the sauce on @startupideaspod (follow for more). Grokbot is really cool. Watch below: youtu.be/qQluNEfSVHk?si=3L2c…

𝕏 Ads just became agent-native... and this is a very powerful upgrade With the new 𝕏 Ads MCP, you can now connect Grok, Grok Build, Claude Code or other AI agents directly to your 𝕏 Ads account and manage campaigns through normal conversation You can literally ask: “How are my ads performing?” And the agent pulls real campaign data, analyzes the results, and tells you what’s working But it goes much further than analytics The AI can: • Create and manage campaigns • Search interests and locations for targeting • Add or remove targeting • Create ad posts • Promote existing posts • Check campaign performance and reach • Update and activate campaigns There are 23 𝕏 Ads tools available through the MCP And the safety design is actually smart: New campaigns and line items are created PAUSED by default, so the AI cannot start spending money until you explicitly activate them The agent can even chain the entire workflow itself: Your request → account → budget → campaign → targeting → ad This is where advertising is heading Instead of living inside Ads Manager, you just tell your AI what you want to achieve and the agent runs the campaign for you

BREAKING: Grok 4.6 just took the #1 spot on CursorBench 3.2 — while delivering a massive efficiency advantage. ⚡💻 • Grok 4.6 Extra High — 70.8% | $2.81/task • Fable 5 Max — 70.5% | $17.32/task • Opus 5 Max — 70.0% | $8.23/task • GPT-5.6 Sol Max — 67.2% | $5.69/task Grok achieved the highest score while costing roughly 6× less than Fable 5 Max and nearly 3× less than Opus 5 Max per task. For AI agents, raw intelligence is only part of the equation. The ability to maintain high performance across long coding tasks without burning massive amounts of compute could be a major advantage. Grok’s agentic coding efficiency is becoming seriously impressive. 🚀 Source: CursorBench 3.2
