OpenAI launches ChatGPT personalization controls: new tone, warmth, and formatting settings for user-tailored AI responses

OpenAI has rolled out a major update to ChatGPT, enabling users to customize the assistant’s tone, warmth, enthusiasm, emoji usage, and formatting style with persistent controls found directly in the app’s settings.

This move addresses long-standing requests for more consistent, user-directed AI behavior, especially for professionals and frequent users who need ChatGPT’s output to match specific communication styles.

Here we explain how these new personalization controls work, what aspects of ChatGPT responses are affected, how these settings interact with Custom Instructions and Memory, and why this release marks a turning point in making AI output truly user-centric.

····················

ChatGPT users now set tone, warmth, and emoji defaults across all chats.

With the latest update, ChatGPT introduces direct personalization options accessible through its settings menu.

Users can adjust the assistant’s overall tone from formal to friendly, control the level of enthusiasm in its replies, and choose how often emojis are used—from none at all to frequent inclusion.

Formatting preferences let users select between more concise, dense output or relaxed, expressive formatting.

Once set, these choices automatically apply to every new conversation, eliminating the need to restate preferences in each prompt or rely on Custom Instructions alone.

····················

New controls refine ChatGPT’s style without changing its knowledge base.

The tone, warmth, and enthusiasm settings adjust how ChatGPT presents itself—affecting things like sentence style, emotional expression, and use of encouragement or affirmation.

Emoji controls give users authority over whether and how often emojis appear.

Formatting options enable better alignment with professional, technical, or creative needs.

Importantly, these controls affect only the style of responses, not the factual content, reasoning, or safety guardrails built into the model.

Formatting and layout preferences support business and documentation use cases.

The new persistent formatting options are particularly relevant for business, technical, and content creation workflows.

Users can instruct ChatGPT to keep responses concise, consistently structured, or more readable for their audience.

This persistent control makes ChatGPT’s output far more predictable in professional scenarios, reducing time spent on manual formatting or post-editing.

Formatting preferences, along with tone and emoji settings, now stay active across all sessions for a seamless experience.

····················

Personalization settings complement Custom Instructions and Memory for deeper control.

ChatGPT now operates with three personalization layers:

• Custom Instructions for explicit guidance on behavior and output

• Memory for storing factual and contextual preferences over time

• Personalization controls for system-level defaults on style and tone

While Custom Instructions and Memory remain critical for complex or factual tasks, the new controls reduce reliance on repetitive prompt engineering.

These changes help ensure that the AI’s personality matches user needs without manual reminders.

····················

How to find and use the new ChatGPT personalization controls.

All new personalization options are accessed from ChatGPT’s main settings, not within individual chat windows.

After adjustment, the assistant immediately begins responding according to the chosen preferences in every new conversation.

These user-level settings are separate from API controls and are currently designed for use within the main ChatGPT app interface.

····················

OpenAI’s approach brings persistent, user-driven customization to AI assistants.

By moving tone and formatting preferences out of prompts and into persistent controls, OpenAI is shifting ChatGPT toward a model where users, not just engineers or product designers, define the default AI personality.

This release responds directly to demand from professional, educational, and creative users for more tailored, reliable AI-generated content.

It positions ChatGPT as a leader in user-centric AI communication, setting a new standard for personalized assistant behavior.
