This workflow is designed to achieve automatic extraction and intelligent parsing of content from PDF documents. Users can directly upload PDF files without the need for OCR recognition, simplifying the process. It simultaneously utilizes two AI models, Claude 3.5 Sonnet and Gemini 2.0 Flash, allowing for a comparison of their performance in data extraction effectiveness, response speed, and cost. It supports customizable extraction instructions, and the output can be adjusted to JSON format, making it suitable for extracting key information from documents such as financial invoices and contracts, thereby enhancing data processing efficiency and automation levels.
Workflow Name
Data Extraction from PDFs and Comparative Analysis of Claude 3.5 Sonnet vs. Gemini 2.0 Flash Capabilities
Key Features and Highlights
- Enables automatic extraction and intelligent parsing of PDF document content by directly processing PDF files without the need for prior OCR, thereby simplifying the workflow.
- Simultaneously invokes two leading AI large model APIs (Anthropic Claude 3.5 Sonnet and Google Gemini 2.0 Flash) for data extraction, allowing users to compare parsing accuracy, response speed, and cost-effectiveness.
- Supports customizable extraction prompts, providing flexibility to define the types of information to be extracted and processed.
- Outputs can be adjusted to JSON structured format as needed, facilitating subsequent data utilization and integration.
Core Problems Addressed
Traditional PDF content extraction typically requires OCR recognition followed by language model analysis, involving multiple cumbersome steps and low efficiency. This workflow converts PDF files directly into Base64 encoding and calls AI large model APIs with native PDF understanding capabilities to complete data extraction in a single step, significantly enhancing automation and operational efficiency.
Application Scenarios
- Automated extraction of key information from PDF documents such as financial invoices and contracts (e.g., VAT numbers, amounts, dates).
- Comparative testing of multiple AI service capabilities to assist enterprises or developers in selecting the most suitable intelligent PDF parsing solution.
- Rapid integration of AI parsing capabilities into automated office workflows, data processing, and document management systems.
Main Process Steps
- Manually trigger the workflow start.
- Define extraction requirements via prompt text, e.g., “Extract VAT numbers from various countries.”
- Download the specified PDF file from Google Drive.
- Convert the downloaded PDF file into Base64 encoded format.
- Simultaneously call the Claude 3.5 Sonnet and Gemini 2.0 Flash APIs, sending the Base64 PDF and prompt to the AI models for content extraction.
- Collect and compare the results returned by both models; users can decide on subsequent processing based on the comparison.
