# Musk says Grok V9 is trained. We've heard this tune.

> Musk said xAI's Grok V9-Medium finished training on 25 May 2026 — unverified, with no release.

*A finished-training tweet is not a shipped model — especially from xAI.*

> **Key:** **The take:** 'finished training' is the AI equivalent of 'the check's in the mail'. Could be true. Could be six weeks and a benchmark asterisk away. With xAI, assume the latter until a model card exists.

On 25 May, Musk said **V9-Medium** — reportedly ~1.5T parameters, ~3× the current production model — had finished training with 'positive' evals. A mid-June release got floated. By mid-June: no firm date, no model card, no independent numbers. Meanwhile the much-hyped *Grok 5* is still training and the betting markets don't believe a June ship.

## Why the skepticism is earned

This isn't generic cynicism — it's pattern-matching. xAI's timelines have slipped repeatedly, 'positive internal evals' is the least falsifiable phrase in AI, and parameter count (1.5 trillion!) is the vanity metric that says nothing about whether the thing is actually good. The shipping flagship is still Grok 4.3. Until V9 is something you can call, it's a press cycle.

> **Note:** **Fair, because credit's owed:** xAI does ship real models, fast, and a 1.5T model landing would be a genuine event. Musk over-promises *and* over-delivers on raw capability often enough that you can't fully dismiss him. The discount is on the timeline, not the ambition.

So: noted, not believed-yet. The grown-up move is to ignore the announcement and wait for the artefact — model card, third-party benchmarks, an API you can hit. When those exist, we'll cover the model. Right now we're covering a claim.

## FAQ

### Should I believe Grok V9 is ready?
Be cautious. Musk said it finished training on 25 May 2026, but there was no model card, release date or independent benchmarks by mid-June, and xAI's timelines have slipped before. It's a credible claim of intent, not proof of a shipped, verified model.

### What's the difference between V9-Medium and Grok 5?
V9-Medium is the ~1.5T-parameter model Musk said finished training; Grok 5 is a separately hyped, larger model still reportedly in training. Both are unverified, and the model xAI was actually shipping at the time was Grok 4.3.
