docs/how_to/merge_message_runs/

Certain models do not support passing in consecutive messages of the same type (a.k.a. "runs" of the same message type).

Some provider(e.g., Ollama and Qwen) returns error(invalid message format) for merged HumanMessage demonstrated in this article. I mean the below merged message.

HumanMessage(content=[{'type': 'text', 'text': "i wonder why it's called langchain"}, 'and who is harrison chasing anyways'], additional_kwargs={}, response_metadata={})

However, GoogleGenerativeAI works well with that.
