ChatGPT appeared like an explosion on all my social media timelines in early December 2022. While I keep up with machine learning as an industry, I wasn't focused so much on this particular corner, and all the screenshots seemed like they came out of nowhere. What was this model? How did the chat prompting work? What was the context of OpenAI doing this work and collecting my prompts for training data?
I decided to do a quick investigation. Here's all the information I've found so far. I'm aggregating and synthesizing it as I go, so it's currently changing pretty frequently.

Сегодня попался рельсовый код, в котором используются монады, сервисы и прочее. Решил сделать обзор с объяснением того, что в коде не нравится и что можно исправить.
Данный разбор основан только на личном опыте и избегает попытку написать самый идеальный код на свете. К сожалению пошарить ссылку на код не могу, потому что автор попросил опубликовать анонимно.
Главная операция, которая вызывается из контроллера выглядит следующим образом:
