The latest ChatGPT update powered by GPT-5 brings some of the most significant upgrades since the AI’s launch, transforming how users interact with the chatbot. From a streamlined interface to customizable response styles, these changes aim to make conversations more personal, intuitive, and efficient. If you’ve been wondering what’s new in ChatGPT 2025, here’s a breakdown of the most exciting updates you’ll notice right away.

Goodbye to the Model Picker

One of the most notable changes is the removal of the model picker for most users. ChatGPT now runs on GPT-5 by default, using an auto-switching system that combines advanced models into a single, faster, and smarter version. This means you no longer have to manually switch between different models like GPT-4o or GPT-4.5 for various tasks—ChatGPT will automatically optimize performance for you. For power users on ChatGPT Plus, Pro, and Team plans, the option to switch between GPT-5 and GPT-5 Thinking is still available, with Pro and Team users getting access to GPT-Thinking Pro for more complex workloads.

Customizable ChatGPT Personalities

ChatGPT is also introducing “personalities” to make conversations more engaging and tailored to your style. You can choose from four unique text-based personalities that adjust tone and delivery to better fit your preferences. Whether you want your AI to be witty and sarcastic, warm and friendly, direct and concise, or deeply analytical, this update makes the chatbot feel more like a personalized assistant. These personality settings are easy to switch, giving you full control over how ChatGPT communicates with you.

A More Streamlined and Modern Interface

The ChatGPT interface is receiving a visual overhaul designed for smoother navigation and better usability. Cleaner menus, faster loading, and improved layout make it easier to focus on your conversation without distraction. This update not only enhances aesthetics but also supports productivity by ensuring that essential tools and settings are quicker to find. Combined with GPT-5’s performance boost, the new interface aims to deliver a faster, more enjoyable user experience for both casual users and professionals.

Faster, Smarter AI Performance

Beyond visual and customization updates, GPT-5 significantly improves ChatGPT’s speed, reasoning, and accuracy. Thanks to advanced model integration, responses feel more natural and context-aware, making the AI better at handling multi-step instructions, generating detailed answers, and maintaining conversation flow. Whether you’re using ChatGPT for creative writing, coding, research, or day-to-day tasks, you can expect quicker, more precise results that adapt seamlessly to your needs.
