xAI and Grok

Elon Musk announced xAI on Jul 12, 2023 and its chatbot Grok on Nov 3, 2023, and promised Grok 5 by the end of 2025, then early 2026. As of Nov 9, 2026 Grok 5 is not out, the newest model is Grok 4.7, and xAI is part of SpaceX, signing as SpaceX Super Intelligence.

32:03 As of Nov 9, 2026, Grok 5 has not been released. The newest model is Grok 4.7, out Sep 21, 2026, and on Sep 14 Musk placed Grok 5 after two more versions: "Grok 4.8 will be a noticeable improvement. Grok 4.9 is probably Astra/Fable class. Grok 5 maybe better than anything" (his post), with no date. He had said in Aug 2025 that Grok 5 would come before the end of that year (Teslarati), and at Baron Capital's investment conference in Nov 2025, in the clip, he said xAI had begun training it and that it would come "in Q1 sometime" of 2026 (Baron Capital). xAI itself is no longer a separate company: SpaceX acquired it on Feb 2, 2026, and its posts now sign as SpaceX Super Intelligence (SpaceXSI). Musk announced xAI on Jul 12, 2023, with the goal to "understand the true nature of the universe" (CNBC).

Status: Late. Last checked: Nov 9, 2026.

Grok itself is delivered and widely used; the status follows the promise this page tracks most, Grok 5, whose dates have passed while it is still officially coming.

What he announced

xAI launched with a team drawn from DeepMind, OpenAI, Google Research, Microsoft Research, Twitter and Tesla (CNBC). Its first product, Grok, came on Nov 3, 2023, described by xAI as "an AI modeled after the Hitchhiker's Guide to the Galaxy" with "a rebellious streak," at first for a limited number of US users.

The biggest claims came with Grok 5. On Sep 17, 2025 Musk wrote "Grok 5 starts training in a few weeks" (post), and on Oct 18, 2025: "My estimate of the probability of Grok 5 achieving AGI is now at 10% and rising" (post).

What happened since

Every Grok version. xAI's news page (read Nov 9, 2026) dates them: Grok-1's weights released openly on Mar 17, 2024; Grok-1.5 on Mar 28, 2024; Grok-2 beta on Aug 13, 2024; Grok 3 beta on Feb 19, 2025; Grok 4 on Jul 9, 2025; Grok 4.1 on Nov 17, 2025; Grok 4.5 on Jul 16, 2026; Grok 4.6 on Aug 12, 2026; and Grok 4.7 on Sep 21, 2026, at $2 per million input tokens and $6 per million output tokens. Musk's dates for 4.7 itself moved at least five times from late Jul 2026, from "four weeks out" to "10 days" on Sep 1 (Decrypt).

Colossus. The first cluster in Memphis came online over Labor Day weekend 2024 with 100,000 Nvidia H100s (Fortune). xAI said Colossus I and II ended 2025 with "over one million H100 GPU equivalents" when it raised a $20 billion Series E on Jan 6, 2026. On Oct 20, 2026 SpaceX said its AI unit expected to bring 200,000 Nvidia Grace Blackwell systems online every month for the rest of the year (CNBC).

The mergers. xAI acquired X on Mar 28, 2025, valuing xAI at $80 billion and X at $33 billion (CNBC); the Twitter Purchase and X page follows X. SpaceX acquired xAI on Feb 2, 2026 in a share exchange valuing the combined company at $1.25 trillion, xAI at $250 billion (CNBC). After Musk's May 6 post, the unit took the SpaceXAI name on Jul 6, 2026 (Teslarati); on Oct 4, 2026, after a White House order to say "Super Intelligence" for AI, Musk replied "Yes, we will make that change" to SpaceXSI (Teslarati).

The money. SpaceX's IPO filing showed xAI lost $6.4 billion from operations in 2025 on $3.2 billion of revenue, and counted 117 million monthly Grok users within 550 million across Grok and X as of Mar 2026 (TechCrunch). In the third quarter of 2026 the AI unit's revenue was $7.56 billion, up from $813 million a year earlier, with a $431 million profit, after the Cursor acquisition and new cloud deals (CNBC).

0:21 Grok Bot and the bundle. On Aug 11, 2026 the company launched Grok Bot, an agent that works in its own computer instance while you keep working, as early users say in its launch film. On Oct 12, 2026 it folded Grok, Cursor and X Premium into The X Subscription, from $8 to $200 a month. Over the Oct 31 weekend users found their weekly Grok Bot limits used up; Musk wrote that "the cost of serving Grok Bot was unsustainably high relative to revenue" (TechCrunch).

Regulators. On Jan 26, 2026 the European Commission opened a Digital Services Act investigation into X over sexually explicit images made with Grok; the company said it had limited Grok's image editing of real people and restricted image tools on X to paid subscribers (CNBC).

We think

We think the next frontier model the company releases is Grok 4.8, not Grok 5, and that Grok 5 is not out by Mar 2027. Musk's own Sep 14 order puts 4.8 and 4.9 first, and Grok 4.7 alone took about eight weeks from his first "four weeks out" (Decrypt).

Confidence: Likely. Check by: Mar 2027.

We think that when Grok 5 does ship, the company will not call it AGI in its own release post. The AGI claims so far are Musk's personal estimates on X, worded as a probability, while the company's release posts describe models by their benchmarks and prices, as the Grok 4.7 post does.

Confidence: Possible. Check by: Dec 2027.
