Gemini flash 2.0 exp native tools use

[Layvier]

Hi,

I'm trying to use the new native search tool in gemini flash 2.0, but I'm not sure how to do so. Is it already supported?

Cheers

I spent the day trying to solve the same question.

For context, along with the new Gemini 2.0 Flash release, Google also released a new, experimental, Python SDK.
The "native search tool" is a tool available in the new SDK.
It is how you use it in the new SDK:

from google import genai
from google.genai.types import Tool, GenerateContentConfig, GoogleSearch

client = genai.Client()
model_id = "gemini-2.0-flash-exp"

google_search_tool = Tool(
    google_search = GoogleSearch()
)

response = client.models.generate_content(
    model=model_id,
    contents="When is the next total solar eclipse in the United States?",
    config=GenerateContentConfig(
        tools=[google_search_tool],
        response_modalities=["TEXT"],
    )
)

for each in response.candidates[0].content.parts:
    print(each.text)
# Example response:
# The next total solar eclipse visible in the contiguous United States will be on ...

# To get grounding metadata as web content.
print(response.candidates[0].grounding_metadata.search_entry_point.rendered_content)

However, this project (langchain-google) relies on the previous SDK.

Now the problem is that the search feature is not available in the previous SDK.

So either:

1. Google makes the search tool available in the previous SDK
2. Langchain-google migrates to the new SDK (still experimental)

I see, indeed I found this issue on the google-cloud-aiplatform sdk repo. Thanks for the clarification 👍
