I took Grok 4 for a spin this weekend to build this game prototype. I used SuperGrok Chat to generate the initial game prototype and then brought it over to Cursor to continue coding with Grok 4 MAX. Grok 4 in Cursor is like a no-nonsense agent. Doesn't speak much, but…
Back to spending 24/7 at work and sleeping in conference/server/factory rooms. I must be super focused on 𝕏/xAI and Tesla (plus Starship launch next week), as we have critical technologies rolling out. As evidenced by the 𝕏 uptime issues this week, major operational…
Our agent team is hiring! job-boards.greenhouse.io/xai/jobs/47991…
Too many crazy stories behind this, and we’ve truly come a long way. Join us to make agents work for real! 🤖🚀
We are hiring! Interested in optimizing/scaling RL framework for pretrain scale RL? DM me or apply here: job-boards.greenhouse.io/xai/jobs/47991…
I'm hiring for our AI safety team at xAI! We urgently need strong engineers/researchers to work across all stages of the the frontier AI development cycle: data, training, evals, and product 1. job-boards.greenhouse.io/xai/jobs/47992… 2. job-boards.greenhouse.io/xai/jobs/47992…
we did some cool work to get a good model, sir - x.ai/news/grok-4. ps: looking for researchers and engineers interested reasoning post-training. reach out if you are interested.
We just unveiled Grok 4, the world’s smartest artificial intelligence. 🧵 Grok 4 outperforms all other models on the ARC-AGI benchmark, scoring 15.9% - nearly double that of the next best model - and establishing itself as the most intelligent AI to date.
My thoughts on Grok 4 Heavy after 12hrs: Crazy good! “Create an animation of a crowd of people walking to form “Hello world, I am Grok” as camera changes to birds-eye.” And it 1-shotted the *entire* thing. No other model comes close. Watch the full clip.
Tried @grok 4 on a dozen non-trivial math (under/)grad level math problems. So far, it has failed to fail me even once. Congrats to @Yuhu_ai_, @ericzelikman and the whole xAI reasoning team, their progress has exceeded all my expectation!
We have some epic updates to voice mode
Of course xAI asked grok to sing an opera song on Diet Coke 😂
This is incredible. Grok 4 is now the leading AI model based on independent testing from @ArtificialAnlys. What's even crazier is that they haven't even tested Grok 4 SuperHeavy yet! "This is the first time that @elonmusk's xAI has the lead the AI frontier. Grok 3 scored…
xAI gave us early access to Grok 4 - and the results are in. Grok 4 is now the leading AI model. We have run our full suite of benchmarks and Grok 4 achieves an Artificial Analysis Intelligence Index of 73, ahead of OpenAI o3 at 70, Google Gemini 2.5 Pro at 70, Anthropic Claude…
Aiming to make @Grok the best tool for developers, from enterprise & government to consumer video games!
Grok is coming to Azure Foundry! Thanks @elonmusk for joining us at Build to talk about what it means for devs.
Grok3 family is a big leap! From cluster build, infra, data curation, pretraining, reasoning, all the way to posttraining and serving, enormous effort put in to get the models out to everyone Very proud! And more to come.
Meet the Grok 3 family, now on our API! Grok 3 Mini outperforms reasoning models at 5x lower cost, redefining cost-efficient intelligence. Grok 3, the world's strongest non-reasoning model, excels in tasks that need real world knowledge like law, finance, and healthcare.
Been working hard pushing Grok 3 Mini reasoning capabilities to the performance/price frontier 🚀 Join our reasoning team to help us build even smarter models!

Grok now remembers your conversations. When you ask for recommendations or advice, you’ll get personalized responses.
We've just released grok studio - it lets you collaborate with Grok on text documents, run code, make browser games. Let me know if you find any issues!
Grok 3 API Is Out And It Is Amazing! We had early access and found that Grok 3 is an insanely good coding model! The instruct model is very robust and unlike reasoners works extremely well in real-life complex scenarios. It will be on Livebench AI and ChatLLM shortly
