This is new content and will be recorded on June11th  2024.

LLMs - Vector database for RAG applications Day 2 Lab

academy/2/course/324/llm_day2_lab/llm_day2_lab.json

Learn the different roles you can play using the ChatGPT Python API, how to interact with GPT-4 using different API configurations, and how to make the most of LLMs to streamline data engineering tasks. In this live lab session, we put GPT-4 to the test and see how well it does at generating an Airflow DAG, writing SQL queries, and crafting dataset documentation.

LLM-Driven Data Engineering Day 1 Lab

academy/2/all-access/large-language-models/day1/lab/lab.json

In this bonus lecture, we dive into one of the hottest topics in tech right now: "Will data engineering be replaced by AI and large language models?" We explore where Large Language Models (LLMs) like GPT-4 are poised to have the most significant impact, identify areas ripe for disruption, and discern the domains where LLMs have a long way to go before they can replace human ingenuity. But most importantly, discover how you can use these insights to harness the power of LLMs and elevate your career as a data engineer.
