Elon Musk’s artificial intelligence startup xAI is rolling out Grok 4 just months after releasing its previous iteration, underscoring the frenetic pace of AI development.

Elon Musk says his AI startup xAI is working on a new application focused on child-safe content, to be called ‘Baby Grok’. The Tesla CEO made the announcement via a post on X but offered no further details on a release date or features.

Grok 4 is xAI’s most advanced model yet, but early praise is clashing with old scandals and fresh tests of its limits.

The latest Grok controversy is revealing not for the extremist outputs, but for how it exposes a fundamental dishonesty in AI development.

The tech billionaire’s artificial intelligence offshoot xAI debuted the new features, allow users to interact with animated characters, on Monday
