GPT-5.1: Subtle AI Changes, Big Disappointment?

OpenAI has released GPT-5.1, its newest iteration of ChatGPT, promising improved performance and more nuanced interaction. The update introduces subtle shifts in tone, aiming for responses that are perceived as warmer and more empathetic. This follows a previous adjustment that made GPT-4o less overtly friendly.

GPT-5.1 features new chatbot personalities, replacing Listener with Friendly and Robot with Efficient, while adding Candid, Professional, and Quirky options. Although custom instructions are reportedly handled with greater accuracy, the practical difference in conversations is often minimal. Performance enhancements in speed and intelligence are noted, though not dramatically noticeable in everyday use.

Ultimately, the impact of GPT-5.1's changes is subtle. While it might appeal to users disappointed by earlier versions, significant personality shifts or customization effects are generally reserved for prompts that naturally allow for them. For deeper AI companionship, dedicated companion apps may still offer superior customization.
