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

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.

Important to use Grok 4.7 with our Build harness for the best results
X.ai/build
grok 4.7 is here, and its our best model so far!
try it out in cursor, grok build, api or anywhere you get your tokens! curious to hear what you think
here's grok 4.6 vs 4.7 building age of empires ii

Grok 4.7 works extremely well with our Build harness
X.ai/Build
Excited 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!

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 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.
Grok 4.7 scores 46 on the Artificial Analysis Intelligence Index to bring SpaceXAI into the top 4 AI labs. Coding Agent Index performance has also improved, overtaking GPT-5.6 Sol
Grok 4.7 scores +2 points over Grok 4.6 on the Intelligence Index, with strong performance on agentic knowledge work tasks. We evaluated the new model at xhigh reasoning effort.
Congratulations to @SpaceXAI and @ElonMusk on the release!
Key takeaways:
➤ Grok 4.7 joins the frontier of agentic knowledge work: Grok 4.7 gains +111 Elo over Grok 4.6 (high) on AA-Briefcase, our private benchmark for long-horizon agentic knowledge work, scoring 1657 Elo and placing it alongside Claude Opus 5 and Claude Fable 5.1 at the frontier. On GDPval-AA, it scores 1695 Elo, +90 ahead of Grok 4.6 (high).
➤ A leap in coding agent performance: Grok 4.7 (xhigh) with Grok Build scores 56 on the Artificial Analysis Coding Agent Index, up +9 points from Grok 4.6 (xhigh). Among models in their native harnesses, Grok 4.7 + Grok Build now ranks 4th, behind only Claude Fable 5.1, GPT-6 Astra, and Claude Opus 5.
➤ Incremental performance changes elsewhere: Outside of agentic knowledge work, Grok 4.7 broadly matches Grok 4.6 (high) on the other Intelligence Index tasks. It improves on Terminal-Bench 4.0 (+4.5 percentage points) and GDP.pdf (+3.0 p.p.), with regressions on AA-LCR (-3.7 p.p.) and AutomationBench-AA (-1.1 p.p.).
➤ High token use across tasks: Grok 4.7's gains come with higher token usage. Grok 4.7 (xhigh) uses approximately 81k output tokens per Intelligence Index task, compared with 36k for Grok 4.6 (high) and 27k for GPT-6 Astra (max) - 125% and 196% more, respectively.
Other model details:
➤ Context window of 500k tokens, unchanged from Grok 4.6
➤ Pricing of $2/$6 per 1M input/output tokens with cache hits discounted to $0.50 per 1M tokens, matching Grok 4.6
➤ Configurable reasoning effort spans low to xhigh. Our evaluation uses xhigh.

Tom Cruise reveals he never reads scripts himself, he has the writers read them to him out loud
"What I do with directors and writers is I don't read the scripts, I have them read it to me.”
“Because I don't want my ideas to invade it yet. I want to understand what is their communication, they've been working on it, they have things that are just there. So they come to me and I just sit there and I'm like, I want you to read it to me"
"And then we get to a place where I start to understand, and I'm like, I know how to contribute to that now. It sparks ideas. I have certain ideas, certain things I'd like to play with, and then I don't necessarily talk about it, I just do it.”
