OpenAI has quietly launched GPT-5.1 Pro, an upgrade from GPT-5, amid fierce competition from Google’s Gemini 3 and xAI’s Grok. This new model is designed to enhance writing help, data science, and business inquiries, with early testers highlighting improvements in clarity, relevance, and structure. GPT-5.1 Pro introduces eight customizable personalities, allowing users to tailor the chatbot’s tone—from sarcastic to caring—making it more engaging for complex tasks. Available exclusively to Pro users, the upgrade replaces GPT-5 Pro, which will remain accessible for 90 days before being retired.

OpenAI is committed to providing users with powerful tools to tackle intricate tasks in an ever-evolving AI landscape. Keep up with these developments for insights into AI advancements and tools.
