GPT-3.5 is a series of advanced language models developed by OpenAI. It is designed to understand and generate human-like text and code. It represents an improvement over earlier GPT-3 models, with enhanced capabilities in natural language processing.

The fine-tuning process involves adapting a pre-trained language model, like GPT-3.5, to perform better on specific tasks or within particular domains. This is achieved by training the model further on a custom dataset that is relevant to the desired application. Essentially, it’s about customizing a general AI to excel in a specialized area.

A LangChain agent is a system that uses a language model to interact with external tools. It decides which tools to use based on user input, and then executes these tools. It is designed to create dynamic, adaptable AI systems that can perform complex tasks by orchestrating various tools and services.

This Generative AI course is designed for experienced AI practitioners and developers who want to push the boundaries of GPT-3.5 capabilities.

For this GenAI course, participants need to have basic knowledge of Python programming, familiarity with Large Language Models like GPT3.5/4, Claude, and Gemini, an understanding of the LangChain framework and agent-based LLM applications, and experience with OpenAI API & basic ML model fine-tuning.
