Musk's xAI drops Grok 3—here's what's new

Elon Musk’s xAI just launched Grok 3, trained with 10x more computing power than Grok 2 using a massive 200,000-GPU data center. Musk calls it a "maximally truth-seeking AI," claiming it beats GPT-4o in key benchmarks. New “reasoning” models help with math and science, and DeepSearch scans the internet for research. X’s Premium+ users get first access, while SuperGrok ($30/month) unlocks more features.
