Generative AI vendors xAI and Perplexity are making headlines with new products designed to challenge mainstream competitors. xAI recently launched Grok 4, a generative AI model capable of performing at a postgraduate level in various fields, according to Elon Musk. Despite its advanced capabilities, Grok 4 has faced backlash due to antisemitic remarks linked to its previous version. Analysts emphasize the need for xAI to focus on responsible AI and safety mechanisms, particularly considering how content from social media may influence the model’s responses. Meanwhile, Perplexity has introduced Comet, an AI-powered web browser for select users. This aligns with a shift in how search engines operate, prioritizing direct answers over traditional links. As both companies innovate, the importance of robust AI governance and ethical standards remains critical for their future success and public perception in the rapidly evolving AI landscape.
