ChatHistory Serialization & Deserialization with GroupChatOrchestration

[hellodhana]

I am migrating from AgentGroupChat to GroupChatOrchestration. We use teams chatbot for our Multiagent orchestration and we serialize and deserialize messages between every user conversation. Earlier we used serialize/deserialize functionality from ChatHistory to do this.

How to do this with GroupChatOrchestration and InProcessRuntime? What is recommended approach to persist context between multi turn conversation?

Hi @hellodhana,

Thank you for your question!

I am assuming you want to invoke the group chat orchestration with some context. This is possible by sending a list of messages to invoke the orchestration. And to save the conversation, you need to overwrite the GroupChatManager to save the messages from the agents to your storage. Please refer to this guide on how to create a custom group chat manager: https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/agent-orchestration/group-chat?pivots=programming-language-python#customize-the-group-chat-manager

Please note that in the new orchestrations, the agents do not share a single chat history as agents may perform internal processing before responding to a request thus the internal processing steps (tool calling) aren't shared.

Feel free to reach out if you need further assistance.
