GPT-5 is OpenAI’s most advanced AI model, designed with significant upgrades in reasoning, coding, and overall user experience. It excels at handling complex tasks that demand step-by-step logic, precise instruction following, and reliable accuracy in critical use cases. The model introduces support for test-time routing and enhanced prompt interpretation, allowing it to adapt to user intent—for example, when asked to “think carefully” about a problem. Key improvements include fewer hallucinations, reduced bias toward agreement, and stronger performance across coding, writing, and health-related applications.
