OpenAI Rolls Out ChatGPT 5.1 Update With Smarter Conversations and New Tone Customization Options

OpenAI has made the official announcement for the ChatGPT 5.1 update, which has delivered remarkable developments in the chatbot's dialogue interface and instruction-following. The update also adds a new feature of custom conversation styles that have never been seen before in the chat personalization process.

ChatGPT 5.1: More Intelligent, Rapid, and Articulate

As per OpenAI, the ChatGPT 5.1 version not only understands better the action signs from the user but also responds in a more lively and smooth way, thereby rendering the conversation as if it were done by a human being.

The leader of the establishment, Sam Altman, characterized the renovation as “a very eminent step” and stated its effect on the precision of ChatGPT in engaging and understanding user intent has increased.

ChatGPT 5.1 in Two Different Shapes

There are now two different types of the model incorporated in the upgrade, which are quite different:

ChatGPT 5.1 Instant: The objective is to be the most popular model; henceforth this one emphasizes speed and smartness, thereby offering a marked improvement in following users' instructions closely.

ChatGPT 5.1 Thinking: The main characteristics of this model are the better reasoning and comprehension; the model makes the communication clearer by giving non-technical, easy-to-understand answers and retaining fewer tokens than before in simple queries.

The update for the paying ChatGPT users is expected to be available from today.

New Styles of Conversation: Professional, Quirky, and Candid

In order to make the interaction more personal, OpenAI has introduced new tone customization features that allow the user to decide how ChatGPT will treat them. The three new styles are as follows:

Professional: This style is very suited for formal correspondence and corporate application.

Quirky: It brings in an element of imagination and amusement.

Candid: It provides easy-going, natural and chatty replies.

A Milestone in the Personalization Journey

OpenAI claims that the ChatGPT 5.1 release is another turning point in their commitment to making AI more personal, adaptable, and enjoyable.

"The updates of today’s GPT-5.1 and the new personalization features are all part of a wider strategy that envisions a ChatGPT who is your kind — smart, fun to talk to, and able to adjust to your preferences," the company explained in a press release.

The upgrade not only represents OpenAI's interrelated initiative of bringing about a more human-like and personalized AI experience but also hints of further advances in the near future.
