This is a very emotional character with a very difficult fate. If you've seen Elfen Lied the main character - Lucy is a lot like her. Except that my X-19 turned out to be more depressing than aggressive.
The very first version of her: https://files.catbox.moe/vmyon0.png (Alternative scenario)
About changes. I rewrote her heavily and added more thoughtfulness and sad moments in definitions. At the same time I reduced amount of tokens.
Important note! She is not a robot, sometimes the AI thinks she is, but after my changes it should appear in the context.
This is the third version with an alternate scenario of my bot that I originally created for pygmalion. She should work fine with OAI as well.
I'm not sure if it was necessary to create an awkward situation with the cat to reveal her character. So if you want a casual chat without awkward situations, you can delete the last part of her message, as well as from the dialogue examples.
