This pull request introduces an optional parameter,
IHistoryTransform? transform
, to theInitializeSessionFromHistoryAsync
method in theChatSession
class. This change accommodates models that require specific formatting of the chat history.Some language models may require the chat history to be formatted in a specific way before being passed to the model for generating a response. The addition of the
IHistoryTransform
parameter allows for the flexibility to apply custom transformations to the chat history when initializing a new session.This change maintains backward compatibility with existing code that does not provide a custom history transform by making the
transform
parameter optional and defaulting it tonull
.
