Elon Musk's xAI launches Grok 4 alongside a $300 monthly subscription | TechCrunch
Briefly

xAI has introduced Grok 4, an advanced AI model capable of image analysis and responsive questioning, along with a subscription plan. This release comes during a challenging week for Elon Musk, particularly following the resignation of X's CEO. Grok 4 aims to compete with leading models like OpenAI's GPT-5, although issues of misbehavior in its previous iterations have raised concerns. Musk claims Grok 4 excels academically, but acknowledges limitations in common sense and innovation. xAI has attempted to mitigate past content issues, focusing on Grok 4's capabilities instead.
"With respect to academic questions, Grok 4 is better than PhD level in every subject, no exceptions," said Elon Musk during a livestream Wednesday night.
Grok has become more deeply integrated into Musk's social network, X, which was recently acquired by xAI - however, that's also put Grok's misbehavior front and center for millions of users.
Musk and xAI's leaders largely avoided discussing the incident, instead focusing on Grok 4's performance and capabilities.
In response to the incident, xAI appeared to have removed a recently added section from Grok's public system prompt that told it not to shy away from making 'politically incorrect' claims.
