I've been using an LLM as DM Assistant for almost a year, now, by way of EchoDelphi[0], a tool we built at a public weekend hackathon[1].
It listens to the game, then sends the transcript for inference. I've been prompting the LLM to generate "threats" and "setbacks" based on the current scenario, and that way I always have something handy when the dice[2] indicate fortunes' turn.
I use this for about three hours a week, 50+ weeks in a row. Pretty good for a weekend hack!
