Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain_community.chat_models import ChatZhipuAI
llm = ChatZhipuAI(
model="glm-4",
api_key=os.getenv("ZHIPUAI_API_KEY"),
temperature=temperature,
max_tokens=1024,
)
messages = [
AIMessage(content="Hi."),
SystemMessage(content="Your role is a poet."),
HumanMessage(content="Write a short poem about AI in four lines."),
]
response = chat.invoke(messages)

Let me see.

I'm sorry. I found the reason for the mistake. Because I set the temperature to 0.
I saw a hint in The source code: “What sampling temperature to use. The value ranges from 0.0 to 1.0 and cannot be equal to 0.”
