BRUSSELS — Elon Musk has denied that X’s artificial intelligence tool Grok generates illegal content in the wake of AI-generated undressed and sexualized images on the platform.

In a fresh post Wednesday, X’s powerful owner sought to argue that users — not the AI tool — are responsible and that the platform is fully compliant with all laws.

“I[‘m] not aware of any naked underage images generated by Grok,” he said. “Literally zero.”

“When asked to generate images, [Grok] will refuse to produce anything illegal, as the operating principle for Grok is to obey the laws of any given country or state,” he added.

“There may be times when adversarial hacking of Grok prompts does something unexpected. If that happens, we fix the bug immediately.”

Musk’s remarks follow heightened scrutiny by both the EU and the U.K., with Brussels describing the appearance of nonconsensual, sexually explicit deepfakes on X as “illegal,” “appalling” and “disgusting.”

The U.K.’s communications watchdog, Ofcom, said Monday that it had launched an investigation into X. On Wednesday, U.K. Prime Minister Keir Starmer said the platform is “acting to ensure full compliance” with the relevant law but said the government won’t “back down.”

The EU’s tech chief Henna Virkkunen warned Monday that X should quickly “fix” its AI tool, or the platform would face consequences under the bloc’s platform law, the Digital Services Act.

The Commission last week ordered X to retain all of Grok’s data and documents until the end of the year.

Just 11 days ago, Musk said that “anyone using Grok to make illegal content will suffer the same consequences as if they upload illegal content” in response to a post about the inappropriate images.

The company’s safety team posted a similar line, warning that it takes action against illegal activity, including child sexual abuse material.
