TinyTroupe is an experimental Python library that leverages large language models (LLMs) such as GPT-4 to simulate characters with specific personalities, interests, and objectives. These artificial agents interact within a simulated environment, enabling us to explore a range of compelling interactions and consumer types, all with highly customizable roles. Unlike game-based LLM approaches, TinyTroupe aims to inspire productivity and commercial scenarios, contributing to the success of projects and products.
