HASH

HASH is a free, open-source platform created by the founders of Kaggle, Stack Overflow, Trello and Glitch. It allows users to create simulations quickly and easily, without spending days or weeks trying to figure it out.

Recently, HASH announced that it has integrated with OpenAI's GPT-3 natural language model. This integration allows users to enter their desired initial state conditions in natural language, and GPT-3 will generate a custom init.json file containing agents and their associated properties.
