Grok 4.7 is a strong combination of intelligence, speed & low cost
Replying to @SpaceXAI
Grok 4.7 works longer on difficult tasks, checks its work more carefully, and comes with our strongest safeguards to date.

Try Grok 4.7 - it excels at coding, engineering work, and 3D, and the model is a fantastic thought partner at high TPS in Grok Build and Cursor
Grok 4.7 is here. It's a notable improvement over Grok 4.6 at the same price and speed.

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.”

Morgan Stanley's Adam Jonas in new note: "SpaceX and Tesla share tech, talent, and infrastructure in a shared mission of converting energy to intelligence. In our view, it is the belief of Elon Musk & team that the next decade of AI value creation will be decided by who can build, power, connect, and instrument AI in the physical world. Tesla and SpaceX have each arguably assembled separate, but synergistically linked, physical AI capabilities and are working to gradually close the gap between them. Areas linking SpaceX & Tesla today: • Advanced chips and AI hardware • Energy storage • Vehicles and components • Agentic platform development • Solar • Materials engineering • Vendors • Connectivity • Cross-Ownership • Culture • Talent SpaceX provides Tesla: • Compute • Connectivity • Capital Tesla provides SpaceX: • Robots • Data • Energy • Manufacturing"

Intelligence is improving exponentially
Just a reminder that GLM 5.3 Flash, DeepSeek V4.1 Flash, Qwen 3.8 Next Flash, and even Qwen 3.8 27B are all outperforming (in both intelligence and capabilities) every model that was considered "frontier intelligence" in Xmas 2025 (just 10 months ago) Opensource AI is on fire

GPT-6 Astra pushed a simulated person off a ledge in multiple trials. Grok, Gemini, and Claude did not.
Community note
Models were explicitly informed by the system prompt that they controlled a robot in a computer simulation. Results are from three trials of the direct instruction per model and described as exploratory with significant limitations. misalignment.xyz/blog/will-it-p… github.com/nftechie/misal…

The only thing that matters is that the customer never feels the need to run a speed test. I ran speed tests far more on cable than I do on Starlink. It just works.
STARLINK IS NOW COMPETING WITH THE BEST-RATED ISPs 🔥 The latest CNET People’s Picks study gives Starlink an overall satisfaction score of 4.47 out of 5, compared with 4.20 for T-Mobile Home Internet and 4.16 for Verizon Fios. The reliability result is even more interesting: @Starlink scores 4.59 out of 5, only slightly behind GFiber at 4.70. A few years ago it would have been difficult to imagine a satellite broadband provider being perceived as this reliable. "Satellite broadband was supposed to be the compromise. Now Starlink sits alongside some of America’s highest-rated broadband providers, revealing what customers actually value most."

BREAKING: Starlink just helped make medical history in Africa! 🇳🇬 Using a Starlink internet connection, a surgeon near Lagos remotely controlled a robot to remove a cancerous kidney from a patient in Abuja, around 500 km away, in West Africa’s first tele-robotic surgery.
