Prompt Templates for GPT 3.5 and other LLMs - LangChain #2

Video Description

In the second part of our LangChain series, we'll explore PromptTemplates, FewShotPromptTemplates, and example selectors. These are key features in LangChain that support prompt engineering for LLMs like OpenAI's GPT 3, Cohere, and Hugging Face's OS alternatives. LangChain is a popular framework that allows users to quickly build apps and pipelines around Large Language Models. It integrates directly with OpenAI's GPT-3 and GPT-3.5 models and Hugging Face's open-source alternatives like Google's flan-t5 models. It can be used for chatbots, Generative Question-Answering (GQA), Retrieval Augmented Generation (RAG), summarization, and much more. The core idea of the library is that we can "chain" together different components to create more advanced use cases around LLMs. Chains may consist of multiple components from several modules. We'll explore all of this in these videos.
