Because langchain iterates very quickly, many APIs change at a very fast pace, and it seems that compatibility issues are not taken into consideration.

The main files involved are: https://github.com/zilliztech/GPTCache/blob/main/gptcache/adapter/langchain_models.py

Previously, we mainly connected to the relevant models of langchain by inheriting BaseChatModel. However, this method is not very good. It is recommended to directly set the cache module in langchain, which is also connected to gptcache
