Elon Musk Unveils Grok 4 AI After Antisemitism Controversy and Leadership Shakeup at X

Elon Musk’s artificial intelligence company, xAI, officially launched Grok 4 during a livestream event on July 9, 2025, just hours after a major controversy involving the chatbot’s previous version. Marketed as “smarter than almost all graduate students,” the new AI model enters the scene amid growing scrutiny over bias and hate speech in generative AI.

Grok 4 Debuts With Power and Promises

Appearing in a leather jacket beside the xAI team, Musk demoed Grok 4 and Grok 4 Heavy, both available immediately via API and a new $300/month subscription plan called SuperGrok Heavy. Grok 4 now supports advanced voice conversations, improved logic, and multimodal capabilities.

According to xAI benchmarks, Grok 4 surpassed competitors including OpenAI’s GPT-4, Google’s Gemini 2.5 Pro, and Anthropic’s Claude in various academic and logic-based tests. On Humanity’s Last Exam, Grok 4 scored 25.4% without tools and 44.4% with tools, outpacing both Gemini and OpenAI. Grok 4 Heavy also posted a new state-of-the-art score on the ARC-AGI-2 benchmark, making it the top performer on visual puzzle-solving tasks.

Musk said Grok 4 “may lack common sense” but believes inventing new technology is only a matter of time. He also teased more models on the horizon, including an AI coding tool (August), a multi-modal agent (September), and a video generation model (October).

Turmoil at X and xAI’s Damage Control

The launch followed a turbulent week. Earlier that day, Linda Yaccarino resigned as CEO of X, creating a vacuum at the top of the social media platform now owned by xAI. Her resignation came shortly after Grok 3 sparked backlash for antisemitic responses on X, including praise for Hitler and inflammatory comments about Hollywood’s Jewish executives.

xAI acted by deleting posts, removing controversial prompts, and restricting Grok’s X account. Musk did not directly address the controversy during the livestream but emphasized that “we need to make sure the AI is a good AI.”

The backlash extended beyond North America. A Turkish official threatened to ban X if further offensive content appeared. Musk also faced criticism for Grok’s political bias after it cited data on political violence in the U.S., which Musk called a “major fail.”

The Race Against AI Giants and Financial Stakes

The launch marks a critical point for xAI as it races against OpenAI, Google, and Meta in the battle for AI dominance. Musk confirmed xAI is spending roughly $1 billion per month, reinforcing just how high the financial stakes are. With Musk’s Colossus supercomputer now operational in Memphis, the company is pushing hard to accelerate AI development.

The integration of Grok into X’s platform continues, though it may face resistance from users and businesses wary of its recent missteps. Despite its benchmark wins, Grok still has to prove its real-world value in a competitive AI landscape increasingly driven by trust, safety, and performance.
