ChatGPT Release Notes

GPT-5.3 Instant mini in ChatGPT

Today, we’re releasing GPT-5.3 Instant Mini in ChatGPT. It replaces GPT-5 Instant Mini as the fallback model users reach after hitting their rate limits for GPT-5.3 Instant. Because it serves as a fallback, it won’t appear in the model picker.

Compared with GPT-5 Instant Mini, GPT-5.3 Instant Mini feels more natural in conversation, with stronger writing and contextual awareness throughout chats. It outperforms GPT-5 Instant Mini across a range of use cases.

New Pro plan options

We’re introducing a new $100/month Pro plan and updating how Codex usage works across Plus and Pro.

• Pro ($100/month): Built for longer, high-intensity Codex sessions. It includes unlimited access to GPT-5.4, access to GPT-5.4 Pro, and, for a limited time, up to 10x more Codex usage than Plus (up from 5X standard usage allowance).
• Pro ($200/month): Our highest-usage option remains available and continues on its current Codex promotion through May 31.
• Plus ($20/month): Plus remains best for steady, day-to-day use. As the temporary Codex promotion on Plus ends, we’re rebalancing Plus usage to support more sessions across the week, rather than longer, high-intensity sessions on a single day.

You can upgrade, switch, or cancel your plan from Settings > My Plan or from the Pricing page.

Outlook shared mailboxes and calendars in ChatGPT

The Outlook Email and Calendar apps for ChatGPT can now help with delegated or shared Outlook resources, when you have access. You can ask ChatGPT to read messages from a shared mailbox, browse its folders, mark mail read or unread, move messages, or send plain-text email from or on behalf of that mailbox. For shared Outlook calendars, ChatGPT can help create, update, RSVP to, cancel, delete, or add small attachments to events.

To use this, connect the Outlook Email or Outlook Calendar app and provide the exact shared mailbox address or target calendar when asking ChatGPT. Availability may depend on your Microsoft permissions and workspace app settings.

A simplified sidebar on mobile

To give you more space to view your most critical chats and projects, the sidebar menu is now simplified on iOS and Android. ChatGPT experiences available to you based on your plan and usage—like Images, Codex, Pulse, and Apps—now appear in a horizontal bar above your chats and projects.

Location Sharing

Users can now choose to share their device location so ChatGPT can provide more relevant information, such as local recommendations, news, and weather. Sharing your device location is completely optional and off until you choose to enable it. You can update device location sharing in Settings > Data Controls at any time.

Enabling location sharing will also enable precise location. Precise location means ChatGPT can use your device’s specific location, such as an exact address, to provide more tailored results. For example, if you ask “what are the best coffee shops near me?”, ChatGPT can use your precise location to provide more relevant nearby results. On mobile devices, you can choose to toggle off precise location separately while keeping approximate device location sharing on for additional control.

ChatGPT deletes precise location data after it’s used to provide a more relevant response. If ChatGPT’s response includes information related to your specific location, such as the names of nearby restaurants or maps, that information becomes part of your conversation like any other response and will remain in your chat history unless you delete the conversation.

Parents who have set up parental controls can choose to disable device location sharing for their teen.

Rolling out to all ChatGPT consumers plans on iOS and web today. Android is coming soon.

Large pastes are now handled as attachments

Starting today for ChatGPT Plus, Pro, and Business users, long pastes are handled differently in ChatGPT.

If you paste more than 5k characters into the composer, ChatGPT will automatically convert the content into an attachment instead of inserting it directly into the text field. This keeps the composer cleaner and helps prevent large pastes from consuming your entire context window.

You can still move the content back into the message at any time by clicking on Show in text field to convert the attachment back to a direct paste.

Google Drive app unification

Google’s file connectors in ChatGPT are now unified under Google Drive, providing a single app experience for interacting with your Google Docs, Sheets and Slides on Google Drive.

If you’re a new user, you can connect to the Google Drive app in ChatGPT to use Google Drive, Docs, Sheets, and Slides actions, removing the need to install and authenticate separate Google file apps. If you’ve already connected to the separate apps in the past, they will continue to work as normal. You can also reconnect the Google Drive app to get the new actions - ChatGPT will switch over once you’ve done the reconnection.

For Pro users, Google Drive sync behavior is unchanged.

We’ve improved shopping in ChatGPT to make it easier to discover, compare, and decide on products.

Product results are now more visually rich, with improved detail and relevance. You can browse products in chat, refine results through conversation, and upload images to find similar items. Products can also be compared side by side with key details such as price, reviews, and features, making it easier to compare without opening multiple tabs.

We’ve also improved product data coverage, freshness, and speed so results are more up to date and useful. These improvements are rolling out to all ChatGPT users this week.

These updates improve how ChatGPT retrieves and presents product information from merchants and other providers using the Agentic Commerce Protocol (ACP).

Now, it’s easier to find, reuse, and build on your files over time. When you upload or create a file—whether it’s a PDF, spreadsheet, image, or more—it’s automatically saved to your Library. Generated images will continue to appear in the Images tab.

You can quickly reference files in a chat using recent files in the composer, or browse everything you’ve uploaded in the Library tab in the sidebar. You can also ask ChatGPT about files you’ve saved (“What should I know about the document I uploaded yesterday?”)

Library is available on web only. ‘Recent files’ in the composer and file search in ChatGPT are supported on iOS and Android.

Files remain in your Library until you delete them. Files uploaded in Temporary Chat are not saved to your Library.

Availability

Rolling out globally for Plus, Pro, and Business users, coming soon to users in the European Economic Area, Switzerland, and the United Kingdom.

Codex for Students is now available for verified university students in the United States and Canada.

Eligible students can claim $100 in ChatGPT credits, or 2,500 credits, to extend Codex usage beyond the limits included in ChatGPT Free, Go, Plus, and Pro.

To get started, students sign in at chatgpt.com/codex/students and complete student verification through SheerID with their university email. Credits are applied automatically to the student's personal workspace, can be used in Codex, are not API credits, and expire 12 months after the grant date.

GPT-5.4 mini rollout in ChatGPT

We’re rolling out GPT-5.4 mini in ChatGPT. GPT-5.4 mini is available to Free and Go users via the “Thinking” feature in the + menu. For all other users, GPT-5.4 mini is available as a rate limit fallback for GPT-5.4 Thinking.

For Plus, Pro, and other paid users, GPT-5.4 mini will be used as a fallback for GPT-5.4 Thinking when rate limits are reached, helping with continued access to reasoning capabilities during high usage. Enterprise customers will retain the option to default Auto routing to GPT-5.4 mini, if preferred.

GPT-5.4 mini will not appear as a selectable model in the model picker, and GPT-5 Thinking mini will be retired as a selectable option in 30 days. Learn more in our blog post.

Updates to the model picker in ChatGPT

We’ve simplified the model picker to make it easier to choose the right level of reasoning.

Users on Plus, Pro, Business, Enterprise, and Edu accounts will see a set of model options depending on their plan, including:

• Instant – fast responses for everyday questions

• Thinking – deeper reasoning for more complex tasks

• Pro – the most advanced reasoning models

The Auto functionality can be accessed by clicking Configure in the model picker menu and choosing "Auto-switch to Thinking.” This setting will automatically be on if your last chat was set to Auto.

Configure more advanced settings

If you want more control, click Configure to:

• Turn automatic switching between Instant and Thinking on or off

• Access legacy models

• Set thinking effort when Thinking or Pro is selected

We’ve also simplified the retry menu, making it easier to regenerate responses with Thinking or Pro models by clicking on the three dots underneath the response.

Sunsetting the “Nerdy” base style

We’re sunsetting the preset Nerdy base style to simplify options and improve response quality. Users who selected it will be moved to the default personality. You can manage personality settings anytime in ChatGPT under Settings → Personalization.
