OpenAI Walks a Tricky Tightrope with GPT-5.1’s Eight New Personalities

OpenAI's GPT-5.1 introduces two new models and enhanced personalization features to improve conversation warmth and instruction-following for paid subscribers first.

  • On Wednesday, OpenAI upgraded ChatGPT's GPT-5 series by adding GPT-5.1 Instant and GPT-5.1 Thinking, with Enterprise and Edu plans receiving a seven-day early-access toggle on Thursday.
  • After GPT-5's auto-selection change, users pushed back over lost personalization, and OpenAI faced strong backlash three months ago, prompting restored choice for more than 800 million people using ChatGPT.
  • The update adds new personality presets including Professional, Candid, and Quirky, while OpenAI says GPT-5.1 is warmer and better at following instructions, using adaptive reasoning for complex prompts.
  • Over the next few days, the rollout will be phased to preserve stability, prioritizing paid subscribers who can use the legacy models dropdown to compare GPT-5 for three months while personalization settings let users tune tone and ChatGPT offers proactive updates.
  • Both GPT-5.1 Instant and Thinking will appear in the API later this week, and OpenAI plans to update GPT-5 Pro soon, impacting more than 800 million ChatGPT users.
