Description

Overview
This workflow helps you compare Claude 3.5 Sonnet and Gemini 2.0 Flash when extracting data from a PDF
This workflow extracts and processes the data within a PDF in one single step, instead of calling an OCR and then an LLM”

How it works
The initial 2 steps download the PDF and convert it to base64.
This base64 string is then sent to both Claude 3.5 Sonnet and Gemini 2.0 Flash to extract information.
This workflow is made to let you compare results, latency, and cost (in their dedicated dashboard).

How to use it
Set up your Google Drive if not already done
Select a document on your Google Drive
Modify the prompt in "Define Prompt" to extract the information you need and transform it as wanted.
Get a Claude API key and/or Gemini API key
Note that you can deactivate one of the 2 API calls if you don't want to try both
