Serializing LangChain objects using these methods confer some advantages: Secrets, such as API keys, are separated from other parameters and can be loaded back to the object on de-serialization; De-serialization is kept compatible across package versions, so objects that were serialized with one version of LangChain can be properly de-serialized with another. py file in the libs/core/langchain_core/load After debugging, the conversion of the ChatPromptTemplate to an actual string prompt results in a serialization of the entire ChatPromptValue object which breaks the contract with the base LLM classes. 237 python version: 3.
