Swiss finance minister Simon Keller-Sutter filed a criminal complaint against X, alleging Grok's AI generated defamatory content. Reuters reported Keller-Sutter specifically asked prosecutors to investigate if X owed a duty of care to prevent such outputs or if the platform knowingly made Grok available for criminal use. If successful, this could force Musk to alter Grok's safeguards in Switzerland.

The case highlights the unresolved legal question of whether chatbot outputs constitute defamation, a debate ongoing globally with little regulatory clarity. Switzerland isn't part of the EU, but Keller-Sutter's failure could prompt local law updates.
