Haystack Tutorials
Haystack is an open-source framework created by the AI company, deepset. It is designed to facilitate the development of production-ready large language model (LLM) applications, retrieval-augmented generative pipelines, and advanced search systems. This framework is tailored to work efficiently with large document collections, enabling users to experiment with cutting-edge natural language processing (NLP) models quickly and with ease.
Project Overview
Haystack Tutorials is the repository that hosts a series of instructional guides intended to help users of all levels. These tutorials are also available on the Haystack website. The goal of these tutorials is to help users explore and leverage the features of the Haystack framework to build robust and intelligent NLP applications.
If you wish to contribute to the Haystack tutorials, you can review the Contributing Guidelines on their GitHub repository to find out more.
Additionally, automated workflows are in place to run these tutorials nightly and publish updates on the Haystack website. These processes are indicated by the badges available in the repository, reinforcing the commitment to maintaining up-to-date resources.
Tutorial Structure
The tutorials are categorized by versions of Haystack, offering different levels of complexity and covering various aspects of using the framework:
-
Haystack 1.x: Tutorials in this category are designed to guide users through building basic question-answering systems to more advanced setups such as scalable systems and FAQ-style question answering.
-
Haystack 2.0: These tutorials delve into the more sophisticated features offered in the latest version of the framework. Users can learn to create retrieval-augmented generative pipelines, structured output generation, and classification systems. It even covers building chat applications and embedding metadata for enhanced retrieval.
Each tutorial is presented with corresponding links to both the code and a Google Colab notebook. This allows users to easily access and run the tutorials in an interactive environment, making it easier to follow along and implement themselves.
