Checked other resources

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

Example Code

import getpass import os from langchain_core.pydantic_v1 import BaseModel, Field

Note that the docstrings here are crucial, as they will be passed along

to the model along with the class name.

class Multiply(BaseModel): """Multiply two integers together."""

a: int = Field(..., description="First integer")
b: int = Field(..., description="Second integer")

os.environ["GOOGLE_API_KEY"] = getpass.getpass() from langchain_google_genai import ChatGoogleGenerativeAI

llm = ChatGoogleGenerativeAI(model="gemini-pro") llm_with_tools = llm.bind_tools([Multiply]) llm_with_tools.invoke("what's 3 * 12")

Error Message and Stack Trace (if applicable)

langchaingemsample.py", line 20, in llm_with_tools = llm.bind_tools([Multiply]) ^^^^^^^^^^^^^^ AttributeError: 'ChatGoogleGenerativeAI' object has no attribute 'bind_tools'

bind_tools is not (yet) implemented for ChatGoogleGenerativeAI. Please see https://github.com/langchain-ai/langchain/discussions/19806

Does it realize this function? You need to check it.
