OpenAI also claims that GPT-5.5 Instant is “more capable across everyday tasks,” like analyzing image uploads and knowing when to turn to the web for an answer. GPT-5.5 Instant has “tighter and more to-the-point” responses and will avoid using “gratuitous emojis.”

With GPT-5.5 Instant, ChatGPT is now “more effective” at pulling in context from things like previous chats and your Gmail to give you more personalized responses, too. (This is a feature that Google is investing heavily in for Gemini as well.) And for all ChatGPT models, a new “memory sources” feature will let the chatbot show what context was used to inform personalized responses, and you can delete or correct information if you need.

OpenAI will start rolling out GPT-5.5 Instant on Tuesday to “all ChatGPT users,” though GPT-5.3 Instant will be an option for three months until it’s “retired.” (In the past, users have mourned the loss of older models, so this gives people time to transition.)

The enhanced personalization will roll out first to Plus and Pro users on the web and is “coming soon” to the mobile apps. OpenAI has “plans” to bring it “soon” to Free, Go, Business, and Enterprise users. The memory sources feature is rolling out to ChatGPT consumer plans now on the web “and soon on mobile.”
