Grok 5 Release Date: Everything Confirmed So Far

Last updated: October 2, 2026

The Grok 5 release date is not confirmed, and Grok 5 is not released as of October 2, 2026. xAI has published one official statement about the model: Grok 5 is in training. Elon Musk said on August 4, 2026 that Grok 5 "should be out before the end of this year." The newest model that xAI lists for developers is Grok 4.7, released on September 21, 2026.

This tracker sorts every Grok 5 claim into 4 groups: official xAI statements, statements by Elon Musk, reported information, and speculation. Price, context window, and plan access are unknown, and the page says so where that applies.

What is the Grok 5 release status as of October 2, 2026?

Grok 5 is unreleased, with a stated target of before the end of 2026 and no specific date. The table shows the status of the 6 main points.

Has xAI confirmed a Grok 5 release date?

No, xAI has not confirmed a Grok 5 release date. The xAI model documentation lists no Grok 5 model and names Grok 4.7 as "the most capable model we've built." The xAI release notes run through September 2026 and do not mention Grok 5.

The company's name changed during the wait. TechCrunch reported on February 2, 2026 that SpaceX acquired xAI, and the xAI release notes now describe Grok models as "SpaceXAI's" models. This page uses xAI for the Grok developer and SpaceXAI where the source does.

What has xAI officially said about Grok 5?

xAI has officially said one thing about Grok 5: the model is in training. The statement sits in the company's Series E funding announcement of January 6, 2026: "Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products."

The same post states that xAI raised $20 billion and operates the Colossus I and Colossus II supercomputers. The post gives no release date, no specifications, and no price for Grok 5.

xAI's later official posts stay silent on Grok 5. The Grok 4.7 announcement of September 21, 2026 does not mention Grok 5 or any future model.

What has Elon Musk said about the Grok 5 release date?

Elon Musk has given 3 different targets for the Grok 5 release date since 2025. The most recent target is before the end of 2026.

1. End of 2025. The Information reported in November 2025 that Musk had earlier set a deadline of releasing Grok 5 by the end of 2025.
2. First quarter of 2026. The Information reported on November 14, 2025 that Musk said Grok 5 would be released "in Q1 sometime." International Business Times reported that Musk gave the early 2026 window at the Baron Capital investment conference.
3. Before the end of 2026. Musk said on the SpaceX second quarter 2026 earnings call, held on August 4, 2026: "With Grok 5, which should be out before the end of this year, we will be incorporating the entire corpus of SpaceX data." The quote comes from the call transcript published by The Motley Fool.

The first 2 targets passed without a release. The third target is a statement on an earnings call by the company's chief executive, not a scheduled launch date.

Musk posted about Grok 5 again on X on September 14, 2026. TeslaNorth reports 3 posts from that day:

• Musk wrote that Grok 4.8, a model with 2.5 trillion parameters, "will finish training this week and start RL." RL stands for reinforcement learning.
• Musk answered a question about artificial general intelligence (AGI) with "That will be Grok 5."
• Musk wrote "Grok 5 maybe better than anything."

None of the 3 posts gives a date for Grok 5. The posts could not be opened directly on X for this article, so the wording relies on TeslaNorth's report.

Which Grok models has xAI released while Grok 5 trains?

xAI has released 3 Grok models since July 2026: Grok 4.5, Grok 4.6, and Grok 4.7. The xAI release notes place Grok 4.5 in July, Grok 4.6 in August, and Grok 4.7 in September. xAI's news post dates the Grok 4.7 release to September 21, 2026.

Grok 4.7 is the only reference point for current xAI API prices. The xAI model documentation lists these Grok 4.7 prices for prompts under 200,000 tokens:

Prompts of 200,000 tokens or more are billed at double those rates. These numbers belong to Grok 4.7 and say nothing about Grok 5 pricing.

Two more models sit between Grok 4.7 and Grok 5 in Musk's September 14 posts as reported by TeslaNorth: Grok 4.8 and Grok 4.9. Neither model appears in the xAI documentation. A release order of 4.8, then 4.9, then 5 would fit those posts, but xAI has not published that order.

The site's Grok listing covers the Grok product that is available today.

What is reported about Grok 5 but not confirmed?

Three claims about Grok 5 come from Musk's remarks or from outlets, and xAI has published none of the 3 in its documentation.

• Parameter count. International Business Times reported on November 17, 2025 that Musk described Grok 5 as a 6 trillion parameter model at the Baron Capital conference. xAI has not published a parameter count.
• Training data. Musk said on the August 4, 2026 earnings call that Grok 5 will include "all the data that SpaceX has ever produced" and that "this will make Grok by far the best engineer." The claim is a plan stated by Musk. No model card confirms the training data.
• AGI. International Business Times reported that Musk put the chance of Grok 5 reaching AGI at 10%. Musk's September 14, 2026 post, "That will be Grok 5", repeats the idea. xAI has published no benchmark that supports the claim.

What is speculation about Grok 5?

Three Grok 5 details that circulate on third-party blogs have no official source and no named reputable report behind them:

• A context window of about 1.5 million tokens.
• Two training variants of 6 trillion and 10 trillion parameters.
• A feature called "Reality Engine."

Prediction markets trade on whether Grok 5 ships by December 31, 2026. Market odds are bets, not information from xAI, and this page does not treat the odds as evidence.

What is still unknown about Grok 5?

xAI has not published 6 details about Grok 5:

1. Release date.
2. API price.
3. Context window.
4. Subscription plan access on grok.com and X.
5. API model ID.
6. Benchmark results.

Grok 5 would arrive after 2 rival launches in the last week of September 2026: OpenAI's GPT-6.1 Sol and Google's Gemini 4 Argon, which Google announced on September 30, 2026 with limited access.
