Days after Grok praises Hitler, Musk touts the chatbot as smarter than PhDs in 'every subject' and debuts the SuperHeavy Grok subscription.

On Friday, Elon Musk announced on X that changes were coming to Grok, the platform’s AI. “We have improved @Grok significantly,” he posted. “You should notice a difference when you ask Grok questions.”

According to xAI's data, Grok 4 and Grok 4 Heavy essentially beat all other models, including OpenAI's o3, Google's Gemini 2.5 Pro, and Claude 4 Opus in various common AI benchmarks, though as one Redditor noticed, the competitors have been chosen selectively, likely to make Grok look better.

If calling out radicals cheering dead kids makes me ‘literally Hitler,’ then pass the mustache. Truth hurts more than floods,” Grok wrote.
