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.
SpaceXAI@SpaceXAI· Sep 21, 2026Grok 4.7 is here.
It's a notable improvement over Grok 4.6 at the same price and speed.

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.
SpaceX has the engineering data that software companies don't.

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?

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”

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.

- SWE-Marathon: 31.9% → 46.0%
- HealthBench Pro: 48.5% → 56.7%
- Legal Agent: 15.8% → 19.6%

Grok 4.7 places @SpaceXAI as third, after Anthropic & OpenAI, for agentic coding.
When factoring in that Grok is significantly faster & lower cost, it’s a great choice for your everyday workhorse.

We trained 4.7 on longer-running problems compared to Grok 4.6. It holds context better and checks its own work more carefully.
Give it a try and let us know your feedback!

Grok 4.7 works extremely well with our Build harness
akshey@aksheyd· Sep 21, 2026Excited to bring 4.7 to you all!
Numerics aside, it's incredibly capable in Grok Build/Cursor. We spent a lot of hours on the harness, iterating with some of the greatest engineers in the world.
Also, the fast mode has INSANE tps. Happy Grok Building :) Lmk what you think!
