AI Personas

Character, Memory, and Development

By Denis Ostapenko

An AI persona can speak in a recognizable voice and still lose the thread of its own history. I wanted to understand what has to persist for its character, memory and choices to hold together over time.

The book is in English. The PDF preserves the page layout; the EPUB adapts to your screen.

What has to stay, and what can change?

I follow that question through character design, memory, learning, human interaction and the control of a system that changes over time. Current research supplies methods and results; the engineering argument asks what each one can support, where it fails, and what a useful comparison would have to test.

The book separates the character described in a prompt, the behavior observed in a system and the continuity experienced by a person. Those questions sometimes meet, but they need different evidence.
