PDF Input Bytes

Send raw PDF bytes to a Vertex AI Claude agent and summarize the contents.

Pass raw PDF bytes with File(content=...).

Code

from pathlib import Path

from agno.agent import Agent
from agno.media import File
from agno.models.vertexai.claude import Claude
from agno.utils.media import download_file

pdf_path = Path(__file__).parent.joinpath("ThaiRecipes.pdf")

# Download the file using the download_file function
download_file(
    "https://agno-public.s3.amazonaws.com/recipes/ThaiRecipes.pdf", str(pdf_path)
)

agent = Agent(
    model=Claude(id="claude-sonnet-4-6"),
    markdown=True,
)

agent.print_response(
    "Summarize the contents of the attached file.",
    files=[
        File(
            content=pdf_path.read_bytes(),
        ),
    ],
)
