+It can be seen that the individual API call history contains redundant information of the conversation. For a long conversation the degree of redundancy is high.
 The compact history is more efficient and the individual API call history contains more details.

 - a [`test`](../reference/autogen/oai/completion#test) function to conveniently evaluate the configuration over test data.
