@elonmusk I'm using it right now to build a game engine in C. It's really good.

samuel@marsrepublica· Sep 21, 2026In just the last 90 days:
1. Grok 4.3 — barely top 10. “xAI is dead beyond compute leases.”
2. Grok 4.5 — massive comeback. “Maybe a chance. But Grok will never catch up to the frontier.”
3. Grok 4.6 — they’re frontier. “Still not top 3.”
4. Grok 4.7 — now top 3 in frontier

Been testing Grok 4.7 for the past week or more. It’s been a great improvement over 4.6.
It worked for over 70 hours straight on a goal. Much better attention to detail.
The 500k context window really makes a difference imo. 4.7 much better at things like skill selection; workflows. Found it particularly good with pstack.
Didn’t have access to it in Grokbot, but I really wanted to test it there. Together it’s a great daily driver.

Tesla has for years openly invited other automakers to license FSD. None of them have accepted.
Blake Scholl 🛫@bscholl· Sep 21, 2026Prediction: Tesla will keep FSD an in-house advantage for a couple years, and then once others start getting close will begin licensing it for other cars—just as they opened up the Supercharger network.

Grok 4.7 xHigh is now at the top with just ONE point away from Claude Fable 5.1 Max on Artificial Analysis’ AA-Briefcase benchmark
Claude Fable 5.1 Max — 59%
Grok 4.7 xHigh — 58%
Just a 1-point difference at the very top
And Grok is ahead of GPT-6 Astra, GPT-5.6, Gemini, Kimi, GLM and nearly every other frontier model on the benchmark

Grok 4.7 made this in blender.
I didn't tell it what to make but only that it should be something it can accomplish in 10 minutes or so.
Honestly not bad at all. Not bad at all.
Did they train Grok on blender?

I’ve been testing Grok 4.7… it’s a really great daily driver, and a huge step up over 4.6.
Definitely worth trying!
SpaceXAI@SpaceXAI· Sep 21, 2026Grok 4.7 is here.
It's a notable improvement over Grok 4.6 at the same price and speed.

We put Grok 4.7 from @SpaceXAI to work on a $2 million insurance claim where one deductible error alone changes the calculation by $143,000.
In this Box Agent preview, @grok reconciles the claim against the policy and supporting records. It catches an $82,000 duplicate invoice and a missing $64,000 supplier credit. It also explains why the Business Income waiting period doesn’t apply to Extra Expense.
The result is a cited claims review for the adjuster, with final coverage and payment decisions left to the insurer.
Explore Box AI Studio to build custom agents for your own document-heavy workflows.

I just gave Grok 4.7 a pretty hard problem, involving reverse-engineering a running binary. Beautifully solved. And it's so fast!

Electrical engineering score is a pretty big deal.

BREAKING: Grok 4.7 dominates the Legal Agent Benchmark.
It scored 19.6% on realistic, long-term legal tasks, beating every other model tested. That is nearly 3× Fable 5.1.
Another major win for Grok 4.7 and SpaceXAI.

“I’ve used FSD for like 90%+ of my miles since Saturday morning. Literally feels like magic. Has handled issues on the road better than I would have at times.
Just remarkable technology”
A demo drive might change your life
James Seyffart@JSeyff· Sep 21, 2026I picked up my new Tesla model Y on Saturday. The whole process of picking it up took like 5 minutes. I never want to deal with a car salesman ever again. I immediately had the FSD drive me home for 45 minutes. I’ve used FSD for like 90%+ of my miles since Saturday morning.
