Books by Denis Ostapenko
I write about the tools I use and the work around them. The books look inside language models, follow an application from prototype to working product, and examine how an AI persona can retain its character and memory.
Character and continuity
Character, Memory, and Development
What has to persist for an AI persona’s character, memory and choices to hold together over time? I follow that question through current research and the systems we can build around a model.

Language models and their uses
Understanding Language Models and Putting Them to Work
How language models learn, why a convincing answer can still be wrong, and what it takes to use them in real work. Everyday examples connect the research to decisions you can make yourself.
