Elon Musk’s Grok AI Shocks the Tech World with New Upgrades, Bold Features & Big Controversies
xAI launched Grok 3 in February 2025, claiming it uses ten times more computing power than Grok 2 and outperforms OpenAI’s o3 on some benchmarks. Grok 4 is expected after July 4, 2025, with a coding module. Grok faced backlash in July 2025 for antisemitic outputs, leading to posting restrictions and model retraining. A rogue employee altered Grok’s system prompt in May 2025, prompting xAI to publish prompts and promise new safeguards.
