File Upload App for ChatGPT

ChatGPT doesn't provide a file upload option out of the box. I explained the app I built with Streamlit to handle file upload and allow ChatGPT to fetch file content through the plugin and unique key. 

 

Building Your Own ChatGPT Plugin

I explain how to get started with ChatGPT plugin development. It is essential to understand how to define OpenAPI specification to match endpoints. In this example, you will see a working use case with endpoints providing info on uploading a file and then fetching file data into ChatGPT. 

 

PaddleOCR as a Service with FastAPI

PaddleOCR is a great tool to extract text data from docs, and it can group related words into a sentence. Such functionality can simplify extracted data analysis. In this video, I explain how to run it as a service with FastAPI in Python. 

 

ChatGPT/GPT-4 for Receipt OCR Data Analysis

I show how ChatGPT works with array data generated from OCR engine by extracting text from the receipt document. ChatGPT can parse and understand the data. What is great about it - GPT-4 model automatically maps key/value pairs without any additional metadata. For example, it matches the receipt item and item price. I'm using PaddleOCR to construct OCR input for ChatGPT. 

 

Document AI: How To Convert Colab ML Notebook Into FastAPI App

I explain how I converted Donut ML model fine-tuning code implemented as Colab notebook into API running as FastAPI app. I share several hints how to simplify code refactoring efforts. 

 

Speeding Up FastAPI App with Background Tasks

FastAPI runs background tasks in a parallel thread, which prevents blocking app endpoints when a long task executes. I explain it in this video and show the benefit of running time-consuming operations in background tasks.

 

Optimizing FastAPI for Concurrent Users when Running Hugging Face ML Models

To serve multiple concurrent users accessing FastAPI endpoint running Hugging Face API, you must start the FastAPI app with several workers. It will ensure current user requests will not be blocked if another request is already running. I show and describe it in this video.
