The Building Blocks of Generative AI: A Comprehensive Overview

Generative AI has been making waves in the tech industry, and for a good reason. It has the potential to revolutionize various sectors, from content creation to healthcare. In this article, we’ll delve deep into the building blocks of Generative AI, using insights from Jonathan Shriftman’s article on Medium.

1. Introduction to Generative AI

Generative AI is a subset of artificial intelligence that focuses on creating new content. This could be in the form of text, images, music, or any other form of data. The article emphasizes the rapid advancements in the foundational components of generative solutions. These advancements are not just in terms of technology but also in venture investment.

2. Large Language & Foundational Models

Large Language Models (LLMs) are computer programs trained using vast amounts of text and code. Their primary goal is to understand the meaning of words and phrases and generate new sentences. These models, also known as foundation models, form the basis for various applications. They use vast datasets to learn and, while they might make occasional errors, their efficiency is continually improving.

3. Semiconductors, Chips, and Cloud Hosting

Generative AI models require powerful computational resources. GPUs and TPUs, specialized chips, form the base of the Generative AI infrastructure stack. Cloud platforms like AWS, Microsoft Azure, and Google Cloud provide the necessary resources for training and deploying these models.

4. Orchestration Layer / Application Frameworks

Application frameworks help in the seamless integration of AI models with different data sources. They speed up the prototyping and use of Generative AI models. LangChain and Fixie AI are notable companies in this domain.

5. Vector Databases

Vector databases store data in a way that facilitates finding similar data. They represent each data piece as a vector, a list of numbers corresponding to the data’s features. Pinecone, Chroma, and Weaviate are some of the companies that have developed vector databases.

6. Fine-Tuning

Fine-tuning involves further training a model on a specific task or dataset to enhance its performance. It’s like refining an athlete’s skills for a particular sport. Weights and Bias is a notable company in this field.

7. Labeling

Data labeling is crucial for generative AI models. It involves providing labels to teach the machine learning model. Snorkel AI and Labelbox are leading companies in this domain.

8. Synthetic Data

Synthetic data is artificially created data that mimics real data. It’s used when real data is unavailable or cannot be used.


Generative AI holds immense potential. Its foundational components are rapidly evolving, and keeping up with these advancements is essential for anyone interested in the field. By understanding its building blocks, we can better appreciate its capabilities and the future it promises.

Writing Language Model (LLM)-based apps involve leveraging the power of AI to create applications that can understand, generate, and retrieve text-based content. Here’s a step-by-step guide on how to achieve this:

Use Case of Vector Database

A vector database is a specialized type of database designed to handle high-dimensional data, particularly in the form of vectors. These vectors are mathematical representations of data points in a multi-dimensional space. The primary advantage of a vector database is its ability to perform similarity searches, where the goal is to find vectors that are close to a given query vector in the multi-dimensional space.

Example Applications

The utility of vector databases can be best understood through practical applications. Here are two examples that demonstrate how to use sizing guidelines to choose the appropriate type, size, and number of pods for indexing:

Example 1: Semantic Search of News Articles

Example 2: Facial Recognition for Banking Security

Vector databases offer a powerful solution for applications that require similarity searches in high-dimensional spaces. By understanding the data’s size and dimensionality, one can make informed decisions about the type and number of pods required for optimal performance. Whether it’s searching for semantically similar news articles or ensuring secure facial recognition for banking, vector databases provide the necessary infrastructure for efficient and accurate results.

RAG (Retrieval-Augmented Generation)

RAG is an abbreviation for Retrieval-Augmented Generation, a method that combines the strengths of large-scale pre-trained language models with external retrieval or search mechanisms. The primary goal of RAG is to enhance the capabilities of generative models by allowing them to pull relevant information from vast external sources, such as databases or corpora, during the generation process.

Components of RAG:
