xAI ships Grok 4.6; Elon flags 4.7 and SpaceX training data

xAI shipped Grok 4.6 on August 12. The company account posted the release the same day Elon said the model was out, closing the soft "later this week" window the desk had been tracking.

The SpaceXAI product note frames 4.6 as a step up from Grok 4.5 at the same price, with extra weight on long-running agents and harder interactive or visual work. Official channels list it in Grok Build, Cursor, Grok Bot, and the API. A short first-week token promo followed: Elon told people to try 4.6 and said tokens were doubled for seven days.

On X, Elon called the release "smart, fast & amazing bang for buck," then said 4.6 is "objectively #1 when considering intelligence, speed & cost" and "Pareto gold." Those lines are ranking talk, not a third-party scorecard the desk can independently audit from the posts alone. xAI's news page points at agentic coding and knowledge-work benchmarks, including a claim that 4.6 matches a named peer on the Artificial Analysis Intelligence Index composite. Treat the chart labels as company marketing until independent benches republish.

Same day, Elon sketched the next cut. Reply-posting about Grok 4.7, he said it "will exceed all current models," called out Anthropic as a strong competitor, and argued SpaceX training data is unique enough that he would be "shocked if any model is better at real-world engineering than 4.7." That is a forward claim with no public ship date in the thread beyond the training talk circulating the same window.

What changed for users is availability, not a vague roadmap slide. 4.6 is live on the surfaces xAI named. Pricing language in the company post keeps the 4.5 price point while arguing more capability per dollar. Grok Build V1.0 and Imagine Image 2.0 remain separate product lines already on the desk; 4.6 is the core model bump those tools can call.

Confirmed - Grok 4.6 released August 12 (company + Elon posts) - Available in Grok Build, Cursor, Grok Bot, and API per company post - Same-price framing vs Grok 4.5 in the company note - Short double-token promo called out by Elon

Not confirmed - Independent third-party bench tables beyond company-linked charts - Exact public GA date for Grok 4.7 - Whether every Grok consumer surface flipped on the same hour

What to watch - Whether Cursor / Build agent workloads stick on multi-step tasks the company highlighted - Follow-on SpaceX-data training claims as 4.7 nears
