This blog post will provide you with insights and best practices for developing generative AI solutions. By the end of this guide, you’ll have a clear understanding of what generative AI entails, how it works, use cases, benefits, required tech stacks, and what you should know as a developer overall. Let’s dive in.
What is Generative AI?
Generative AI is a type of artificial intelligence that creates content like pictures, text, or music. You’ve probably used or heard of systems like ChatGPT, Bing, Bard, YouChat, DALL-E, or Jasper, which use generative AI. Generative AI learns from data and generates original content that looks or sounds similar. These days, we use it for entertainment, healthcare, and even finance. However, as impressive as generative AI has become, it’s crucial that we use it responsibly so that we don’t create content that deceives users (we’ll touch on that more later).
How Does Generative AI Work?
Generative AI works by using algorithms to analyze the patterns and relationships within existing data. This data can be anything from text to images to audio. Once the model has learned these patterns, it can use them to generate new data similar to what it was trained on.
There are two ways that generative AI models can generate new data:
Generative Adversarial Networks (GANs): GANs are a type of neural network that consists of two competing neural networks: a generator and a discriminator. The generator tries to generate new data similar to the data it was trained on, while the discriminator tries to distinguish between real and generated data. This competition forces the generator to improve its ability to generate realistic data.
Variational Autoencoders (VAEs): VAEs are neural networks used in generative AI. They encode input data into a compressed representation called the latent space and then decode it to generate similar data.
In summary, generative AI models learn from existing data to create new data through GANs’ competitive process or VAEs’ encoding and decoding.
What Developers Need to Know About Generative AI
Generative AI, also known as generative adversarial networks (GANs), is an area of artificial intelligence that focuses on generating new and original content. As a developer, there are several key things you should know about generative AI:
Understanding the Basics
