> **Key:** **The one-liner:** Musk says a big new Grok finished training — which is an announcement about an internal model, not something you can use.

**What happened.** On 25 May, Elon Musk said xAI's **V9-Medium** — reportedly ~1.5 trillion parameters, around three times the current production model — had finished training, with internal evals described as positive. A mid-June release was floated.

**The status.** Unverified. By mid-June there was no confirmed release date, model card or independent benchmarks, and the separately hyped Grok 5 remained in training (attribute, don't assert).

> **Note:** **Why caution.** xAI's release timelines have repeatedly slipped, and the shipping flagship was still Grok 4.3. Watch for an actual model card and third-party benchmarks before treating V9 as real.

## Key takeaways

- What: Musk said a ~1.5T-parameter model, V9-Medium, finished training (25 May 2026).
- Status: unverified; no firm release date or model card by mid-June.
- Context: 'Grok 5' still in training; shipping flagship was Grok 4.3.
- Caveat: xAI's timelines have slipped before — treat as intent, not a ship.

## FAQ

### Is Grok V9-Medium released?
No — as of mid-June 2026 it had only reportedly 'finished training' (per Musk, 25 May), with no confirmed release date, model card or independent benchmarks.

### How reliable is the claim?
Treat it as unverified intent. The figures are the company's own, and xAI's timelines have slipped before. The model people could actually use was Grok 4.3.
