Semily's early work involved creating a game town populated with 25 NPCs using GPT-3.5, memory, planning, and reflection capabilities. A key experiment during Valentine's Day showed these agents self-organizing, planning parties, and decorating a cafe, demonstrating emergent complex behavior. This project was a foundational step in developing agents that remember interactions and exhibit personality.
“So what we ended up doing was, well, if we fast forward, years into doing this, what will be the most ambitious vision that we might have, and that was creating entire lived experience of a town.”
“So they would plan parties, they would decorate the cafe. We thought that was really interesting.”
“One was it was one of the earliest example of creating agents. So this particular set of agents were paired with back in the day, GPT3.5 text-end-G, so we didn't quite have ChatGPT back then. And then was paired with memory, planning, and reflection.”
