Day 13: Building Your First LLM-Based Application

Welcome to Day 13 of "Building LLM-Powered Apps," our free course. In this session, our Machine Learning Engineer, Darek Kleczek, demonstrates how to develop a foundational Large Language Model (LLM) application, navigate its complexities, and tackle typical issues.

Chapter Highlights

  • Transitioning to Application Development: Move from basic API usage to the intricate process of creating a fully operational LLM-based app.
  • Addressing API Constraints: Grasp the limitations inherent in using LLM APIs for generating responses and the occurrence of hallucinations in the model's output.
  • Examining Real-world Examples: Explore practical examples from our synthetic dataset to highlight discrepancies in LLM-generated responses.
  • Understanding Knowledge Limits and Hallucinations: Investigate the challenges of knowledge cutoffs in LLMs and the occurrence of hallucinations in the responses they generate.
  • Insights into App Architecture: Begin the process of constructing an LLM application's architecture, addressing various challenges and identifying possible solutions.

Key Course Information

  • No deep machine learning knowledge is needed, just some familiarity with Python programming.
  • Strategies for continual enhancement of your LLM applications.
  • Unique perspectives on the LLM tools used by Weights & Biases.
