PDF as tool output

[alexHeu]

Hi, is it possible to have tool that directly return pdf files from tools?
In the responses API there is the option to add files as base64 strings:
{ "type": "input_file", "filename": "PDF-FILE-NAME.pdf", "file_data": f"data:application/pdf;base64,{base64_string}", },

.NET or Python?

I'm not sure of the answer for Python, but for .NET yes, have your AIFunction return a DataContent for the pdf.
