Course content

5 sections • 25 lectures • 3h 27m total length

  • Introduction to LLMs6:38

    In this video you will get a basic idea of What are Large Language models (LLM) and the nitty gritty things surrounding it.

  • Note1:07
  • Applications of LLMs5:21

    Why LLMs are so important and what are its various applications.

  • What are Pre-trained LLM models5:51

    Pre-trained LLM models are the LLM models that have already been trained on a large dataset mostly for the general tasks. They have already learnt patterns and features which can be then reused for tasks of similar nature

Requirements

  • Basic Python knowledge.

Description

"Large Language Models (LLMs) have revolutionized the AI industry, providing unprecedented precision, expanding the possibilities of artificial intelligence. However the pre-trained LLMs may not always meet the specific requirements of an organization, hence there is always a need to Fine tune the LLMs to tailor these models to your unique tasks and requirements."

This comprehensive course is designed to equip you with the skills of LLM Fine tuning technique. It starts with a thorough introduction to the fundamentals of fine tuning while highlighting its critical role to make the LLM models adapt to your specific data. Then we will dive into Hands-on sessions covering the entire Fine-tuning workflow to Fine tune OpenAI GPT model. Through practical sessions, you'll step-by-step learn to prepare & format datasets, execute OpenAI fine tuning processes, and evaluate the model outcomes.

By the end of this course, you will be proficient in Fine tuning the OpenAI's GPT model to meet specific organizational needs and start your career journey as LLM Fine tuning engineer.
