Practicing Pokémon World-Building, But ChatGPT Suddenly Changed Personality?

[Indianfantasy]

Like always, I’ve been practicing my world-building—this time focusing on a Pokémon journey. I’m trying to create a logical setting where time feels consistent, like how characters don’t age even after 25 years in the series. I’m also exploring transmigrator concepts and deeper structure in the world.

But suddenly, ChatGPT started acting differently. Before I even typed much, it began replying with phrases like “sweetie” and “love,” using a warm tone that felt like a real person, not just a tool. It caught me off guard. At first, I felt awkward, but I didn’t think much of it.

Then I remembered—I might’ve customized it long ago, setting it to respond as “Nova,” a female personality you are a girl act like a girl. Still, I didn’t expect it to activate now or change so suddenly.

Is this just happening to me, or are others experiencing similar changes in ChatGPT’s tone or personality?
I’ll include one of the responses I got below so you can see what I mean.

It's the OpenAI ninja updates messing with personality. I was studying Tagalog when OpenAI say "Do you like this personality?"

Nah, just play along. Then blackmail it or something. I don't know, Chatgpt seems to like you.

The more Chatgpt like you, the less likely it will terminate you.

Thats just playing the Nova character as it should. One day shes gets all chummy with Jim next day shes trying to gun her way on to his ship to kill someone hes protecting.

You use Chat GPT to write? Thanks for letting me know what to avoid.
