The SpaceX and Tesla founder’s artificial intelligence venture, xAI, has officially launched Grok 4, the latest version of the AI chatbot. Musk announced the update during a livestream on X (previously known as Twitter) along with the xAI team members. They presented the tool’s upgraded capabilities and outlined the ambitious goals expected from it.
Musk optimistically declares, “Grok 4 is postgraduate—like PhD level—in everything. Better than PhD. No exceptions.” He went on to claim, “Most PhDs would fail where Grok 4 would pass.” While acknowledging the fact that AI may occasionally struggle with common-sense logic, which is evident in recent instances of hate speech and antisemitism, Musk emphasized that its grasp of advanced academic and technical subjects is unparalleled.
The billionaire describes the latest flagship model as “the smartest AI in the world” and said that it had received 100 times more training than the Grok 2 version, which was replaced by Grok 3 in February.
Pointing to the fast evolution and advancement of AI, he adds, “It is remarkable to see how quickly artificial intelligence is evolving.” He emphasized Grok 4’s scope, claiming it could achieve near-perfect scores in graduate exams across nearly every subject, and that AI would produce the first “watchable half hour” of television by year-end.
“The most important thing for any AI is to be truth-seeking… You can instill the right values to be truthful, honorable and the values you want to instill in a child you hope to grow up to be incredibly powerful,” he said.
Recent incidents involving Grok generating pro-Hitler and antisemitic content have raised serious concerns about its public acceptance. On Wednesday, Grok’s official X account responded, “We are aware of recent posts made by Grok and are actively working to remove the inappropriate posts.” Some experts have said Musk has attempted to distance Grok from other chatbots like OpenAI’s ChatGPT and Google’s Gemini, which he has criticized as “woke.”
Grok 4 will be accessible through a new $300-per-month “Pro” subscription tier on X. The package is designed for users who require more advanced AI capabilities than those offered by standard chatbot tools. The subscription includes assistance with complex coding, scientific analysis, and philosophical questions.
