mistralai: update tool calling (#19451)
```python from langchain.agents import tool from langchain_mistralai import ChatMistralAI llm = ChatMistralAI(model="mistral-large-latest", temperature=0) @tool def get_word_length(word: str) -> int: """Returns the length of a word.""" return len(word) tools = [get_word_length] llm_with_tools = llm.bind_tools(tools) llm_with_tools.invoke("how long is the word chrysanthemum") ``` currently raises ``` AttributeError: 'dict' object has no attribute 'model_dump' ``` Same with `.with_structured_output` ```python from langchain_mistralai import ChatMistralAI from langchain_core.pydantic_v1 import BaseModel class AnswerWithJustification(BaseModel): """An answer to the user question along with justification for the answer.""" answer: str justification: str llm = ChatMistralAI(model="mistral-large-latest", temperature=0) structured_llm = llm.with_structured_output(AnswerWithJustification) structured_llm.invoke("What weighs more a pound of bricks or a pound of feathers") ``` This appears to fix.
