How to resuming a groupchat with chat history?

[zhangjy859]

Hi,

I am attempting to restore a terminated group chat. with the following information available:

1. Complete conversation logs stored in the database.
2. Identical team configuration, including the same agents and llm.

Questions:

Is it possible to restore the group chat? If so, what are the steps required?

There appears to be relevant documentation for version 0.2 (https://microsoft.github.io/autogen/0.2/docs/topics/groupchat/resuming_groupchat/), but the functionality seems unavailable or less feasible in newer versions.

Thanks for your suggestions

yeah this is doable in v0.4, it just looks different from the v0.2 approach.

save_state() and load_state() are the cleanest path:

# at the end of a session, save the team state
state = await team.save_state()
# `state` is a plain dict - serialize it to json or store in your db

# later, to resume:
team2 = RoundRobinGroupChat([...])  # same agents and config
await team2.load_state(state)
result = await team2.run(task="continue from where we left off")

save_state() captures the full message history plus agent and termination condition state. when you load_state() before the next run(), the agents see the prior conversation as context.

if you only have raw logs from a database (not a save_state() snapshot) it is more manual - you would need to reconstruct the messages and inject them via the team or agent context. there is no built-in "replay from raw db logs" api in v0.4 right now, so the practical advice is to add save_state() at the end of every session from the start - much easier than reconstructing state after the fact.

the v0.2 resume docs you linked covered a similar concept but the api changed significantly in 0.4, which is probably why you could not find the equivalent.
