OpenAI Releases GPT-5.1, Along With Renamed and New Personalities

Robot was the personality that changed how I felt about ChatGPT. Before, I found ChatGPT useful but frequently annoying; after, I’ve found it purely useful.

I have not changed these settings in the past, which is to say, I keep it at default. After reading this, I’ve set it as efficient, just to see if I like it better.
