Elon Musk said Monday that the next version of his AI model, Grok 4.6, will be released in two weeks, with a follow-up version, Grok 4.7, arriving four weeks from now. The announcement, made on his social platform X, gives the first concrete timeline for the model's rollout and confirms that Grok 4.6 will contain two trillion parameters, according to reports.
Two-trillion-parameter milestone
The reported parameter count for Grok 4.6 — two trillion — would make it one of the largest publicly known language models. Parameter count is a rough measure of a model's complexity and capacity, though raw size doesn't always translate directly to performance. Musk's xAI has been racing to close the gap with models from OpenAI, Google, and Anthropic, and the jump to two trillion parameters signals a serious scaling push.
Rapid release cadence
The plan to ship Grok 4.7 just two weeks after 4.6 suggests xAI is iterating aggressively. Musk didn't detail what improvements 4.7 would bring, or whether the two releases would differ significantly in architecture or training. The fast turnaround could mean 4.7 is a refinement of 4.6 rather than a ground-up retrain, or it might indicate that xAI is treating the releases as overlapping development cycles.
Musk's announcement came without a technical paper or benchmark results, leaving researchers and users to speculate on exactly how the new models will perform. The company has not said whether Grok 4.6 or 4.7 will be available to the public through the X platform's premium tier, or if there will be API access for developers.
Both releases now have hard dates: Grok 4.6 in roughly two weeks, Grok 4.7 in roughly four. Whether either model lives up to its parameter count will be judged soon enough by the users who get their hands on it.
