+## Why Sotopia?
+Sotopia aims at pushing the boundary of artificial social intelligence through simulating realistic social interaction, supporting human-AI interaction, and evaluating the performance of social agents in a unified way.
+
+**Unlike** other multi-agent frameworks ([CrewAI](https://www.crewai.com/), [CAMEL-AI](https://www.camel-ai.org/), [AutoGen](https://microsoft.github.io/autogen/dev/index.html), and [swarm](https://github.com/openai/swarm)), Sotopia provides a wide range of social tasks and characters with different backgrounds and personalities, and creates a asynchronous and information-imperfect social interaction environment.
