xAI launches new Grok-3 AI model with DeepSearch reasoning

Elon Musk's xAI is betting that reasoning—not just raw power—will define the next generation of artificial intelligence, unveiling Grok-3 with a feature called DeepSearch that mimics how humans methodically work through complex problems. The move represents a quiet but significant shift in how AI companies are competing: rather than simply scaling up models, they're now racing to make them think more deeply, a capability that could reshape everything from scientific discovery to legal research. If the technology works as advertised, it could challenge the dominance of OpenAI and Google in a market where incremental improvements have already begun to plateau.
