Feature request

Yesterday openai released new type of message called "developer" message which replaces system message for newest models.

Langchain does not have a current solution for dynamically adding new message types, we should add new message type "developer" and make it possible to add dynamic types for future.

Motivation

Feature request for new technologies

Proposal (If applicable)

No response

I agree your request. We need developer message on langchain.

if you want to use markdown output ,we can use system role and content is Formatting re-enabled now.
But I recognize I should use developer role.

prompt = ChatPromptTemplate.from_messages([("system","Formatting re-enabled"), ("human","XXXXXX") ])
