On the menu: less<strong>hallucination<\/strong>better <strong>more answers<\/strong> reliable, and a model that adapts to the <strong>request<\/strong> to provide deeper reasoning when needed. <strong>GPT-5 is here<\/strong> - simple, jargon-free deciphering.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">GPT: what is it?
