Cursor has officially joined SpaceX.
We’re grateful to become part of such a special company, and it has been a privilege working with the SpaceXAI team. Lots ahead.
Cursor@cursor_ai· Aug 14, 2026Cursor is now part of @SpaceX.
Today, we have officially closed our acquisition. We will join the @SpaceXAI team to help make Grok the world's most useful AI and improve Grok Build, Grok Bot, Grok API, Cursor, and more.
SpaceX has built some of the most inspiring and

Grok 4.6 will work best with the Grok Build harness. The experience will be significantly worse without it, so best to evaluate using Build.
Arthur MacWaters@ArthurMacwaters· Aug 13, 2026From my use so far, 4.6 seems highly optimized for Grok Build

Thrilled to receive this feedback from Tesla — they tackle the world’s most critical multimodal challenges.
Extremely proud that the team’s work is paying off🚀
Yun-Ta Tsai@yunta_tsai· Aug 14, 2026Grok 4.6 multimodal is a step change from Grok 4.5. It’s one of the under-discussed improvements, and I’ve been very impressed by it.

Grok 4.6 ranks #1 on CursorBench for real-world coding
X Freeze@XFreeze· Aug 14, 2026Grok 4.6 just ranked #1 on CursorBench 3.2
Outperforming Claude Fable 5, Opus 5 and GPT-5.6 Sol on real-world coding performance
And what makes this even crazier is the efficiency....the chart gives CursorBench performance against average cost per task, and Grok 4.6 is sitting

Grok 4.6 from @SpaceXAI on ARC-AGI (Verified):
- ARC-AGI-1: 87.5%, $0.30/task
- ARC-AGI-2: 67.1%, $0.76/task
- ARC-AGI-3: 2.11%, $5.6K
On ARC-AGI-3, Grok 4.6 with xhigh reasoning scored comparably to GPT-5.6 Sol with high reasoning, but cost $5.6K versus Sol's $15.2K.

Use Grok 4.6 for CAD
adam@adamdotnew· Aug 13, 2026Grok 4.6 is frontier-adjacent intelligence for agentic CAD work at a fraction of the cost.
It holds the best price-to-intelligence ratio of any model we've tested so far.

He built the computer vision system in my oven. (True story).
So when he praises something I listen a little harder.
Matt Van Horn@mvanhorn· Aug 14, 2026Grok @Bot is really good. Haven't felt this kind of magic since I set up my OpenClaw for the first time. I know it's expensive if you don't have Grok already to get a new $200-$300 plan, but it's worth it to live in the future.

I’ve had my @Tesla for 9 days—and it’s already saved my life. Full Self-Driving with HW4 is mind-blowing.
My car drove me ~800 miles from Georgia to Texas without me touching the wheel or pedals, while avoiding multiple collisions.
I’ve never felt safer in a vehicle.
Here’s one example of a collision avoided, automatically captured on camera.
In this instance (though it doesn’t show my actual POV), sparks covered the windshield, lighting up the road like the Fourth of July and obstructing my view. Since I was in FSD, the car reacted immediately without overcorrecting like I likely would have, which could have led to a far worse outcome.
Everyone who’s ridden with me and experienced FSD for the first time is blown away and now looking into buying one—including my parents, who like me have never owned an EV.
There’s no telling how many lives this technology will save. This is hands-down the most incredible purchase I’ve ever made.
God bless @elonmusk & the Tesla team🫡
