X said it had removed the posts and that the problem was not related to the chatbot’s underlying large language model.

Still, the Commission has called the company in for a “technical meeting” on Grok, spokesperson Thomas Regnier said.

X is designated as a very large online platform under the EU’s Digital Services Act, meaning it has to follow strict transparency requirements.

The Commission has not responded to POLITICO’s inquiry as to whether the platform submitted a risk assessment for the integration of Grok into X. Meta submitted such a document for the integration of AI features on its platform, Regnier previously told POLITICO.

X is also under investigation for breaches of the DSA on several fronts, including the dissemination of illegal content.
