Announcing Grok for Government - a suite of products that make our frontier models available to United States Government customers

We are especially excited about two new partnerships for our US Government partners

1) a new contract from the US Department of Defense
2) our products being available to purchase via the General Services Administration (GSA) schedule. This allows every federal government department, agency, or office, to purchase xAI products

We're hiring mission driven engineers who want to join the cause x.com/i/jobs/1899898…

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. Humanity's Last Exam (HLE) is a rigorous intelligence benchmark featuring over 2500 problems crafted by experts in mathematics, natural sciences, engineering, and humanities. Most models score single-digit accuracy. Grok 4 and Grok 4 Heavy outperform all others.

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. Let’s start with Grok 3 Mini.

When we set out to build a fast, affordable mini model, we knew it would be good but even we didn’t expect it to be this good. Some highlights:

- Grok 3 Mini tops the leaderboards on graduate-level STEM, math, and coding, outcompeting flagship models that are 20x more expensive.

- 5x cheaper than any other reasoning model on the market, setting the gold standard for cost-effective intelligence.

- You get access to the full raw, unedited reasoning trace in every API response.

This is it: The world’s smartest AI, Grok 3, now available for free (until our servers melt).
