Just two months after GPT-5, OpenAI has launched two new conversational AI models: GPT 5.1 Instant and GPT 5.1 Thinking. While these models boast technical improvements, the spotlight is on the introduction of eight new personalities available for user interaction.
New Personalities for Enhanced User Experience
OpenAI has diversified GPT-5 by integrating eight distinct personality modes: professional, friendly, sincere, quirky, efficient, cynical, nerdy, and the default setting, reminiscent of the classic ChatGPT. These personalities alter the tone without affecting the accuracy of the information provided, addressing past criticisms of GPT-5 being overly warm or flattering.
Models Tailored for Diverse Needs
- GPT 5.1 Instant is designed for speed, ideal for users who need quick responses.
- GPT 5.1 Thinking offers more detailed answers, suitable for tasks that require deeper analysis.
Initially, these models are rolling out to paid subscribers and will gradually become available to free users.
