IGroupChat is a fundamental feature in AutoGen. It provides a way to organize multiple agents under the same context and work together to resolve a given task.

In AutoGen, there are two types of group chat:

• RoundRobinGroupChat : This group chat runs agents in a round-robin sequence. The chat history plus the most recent reply from the previous agent will be passed to the next agent.
• GroupChat : This group chat provides a more dynamic yet controlable way to determine the next speaker agent. You can either use a llm agent as group admin, or use a Graph, which is introduced by this PR, or both to determine the next speaker agent.

Note

In GroupChat, when only the group admin is used to determine the next speaker agent, it's recommented to use a more powerful llm model, such as gpt-4 to ensure the best experience.
