GPT-5 has finally arrived. Along with the announcement of the highly anticipated AI model, OpenAI also previewed several updates coming to ChatGPT, ranging from visual changes to improvements to the chatbot’s performance.

Here’s a rundown of all of the changes you can expect to see in ChatGPT.

With the rollout of GPT-5, OpenAI is getting rid of the model picker and retiring many of its older models, including GPT-4o, GPT-4.1, and GPT-4.5. ChatGPT now runs on GPT-5 by default. It has a “single auto-switching system” that combines its new models into a “faster, smarter model,” theoretically eliminating the need to swap between models for different purposes.

However, ChatGPT Plus, Pro, and Team users can still use a model picker that allows them to switch between GPT-5 or GPT-5 Thinking. Pro and Team users will also get access to GPT-Thinking Pro.

One of the biggest updates coming to ChatGPT is the ability to select from four new “personalities” for text-based responses. Here’s how OpenAI describes each of them:

Cynic: Sarcastic and dry, delivers blunt help with wit. Often teases, but provides direct, practical answers when it matters.

Robot: Precise, efficient, and emotionless, delivering direct answers without extra words.

Listener: Warm and laid-back, reflecting your thoughts back with calm clarity and light wit.

Nerd: Playful and curious, explaining concepts clearly while celebrating knowledge and discovery.

These new personalities sound like they might be fun to play around with. But if you’re not a fan, you can always switch back to ChatGPT’s “default” style.

Vibe coding, or the process of having AI generate code based on natural language prompts, just got an upgrade on ChatGPT. OpenAI says GPT-5 is even better at processing complex and descriptive prompts when asking it to create an app or website. You can then see — and interact — with a preview of what the AI chatbot has built by opening Canvas.

OpenAI is rolling out new ways to customize ChatGPT’s interface. With this update, you can set an accent color that will change the appearance of your conversation bubbles, voice button, and highlighted text.

To do this on the web, click your profile icon, select Settings > General. From there, select an option from within the Accent color drop-down. You can do the same thing on mobile by tapping your profile picture, heading to Personalization, and tapping Color Scheme.

ChatGPT’s advanced voice mode, which allows for more natural-sounding spoken conversations, is getting an update for paid users that will make it better at understanding instructions, as well as allow subscribers to tweak its speaking style.

OpenAI also announced that it’s retiring standard voice mode, but it’s offering “near-unlimited” use of advanced voice mode for paid users, and bringing “hours” of extra usage to free users in exchange. Advanced voice mode now works with custom GPTs, too.

Lastly, OpenAI is making it easier to link your Gmail account and Google Calendar to ChatGPT. As explained in a demo, ChatGPT will now ask you to connect your Gmail or Calendar when you enter a prompt, such as “help me plan my schedule tomorrow.” Once you link your account, ChatGPT will draw from your schedule and your emails to plan out your day, notify you about missed emails, and more.

The ability to connect these accounts is coming to Pro users next week, “with other tiers coming next.”
