What is generative AI?

What exactly is generative AI? We will explain in detail the definition, mechanism, differences from conventional AI, and types of generative AI.

Meaning and mechanism of generative AI

Generative AI is a type of artificial intelligence and refers to an AI system that has the ability to generate new information and content from data. Generative AI can automatically generate data such as text, images, audio, and video, and many of the products are as creative as if they were created by a human.

How it works is by using machine learning and deep learning approaches to learn patterns and rules from large amounts of data, and then generate new content based on that.

What is traditional AI?

In contrast to generative AI, which is currently becoming mainstream, the conventional main type of AI is identification AI. Generative AI focuses on generating new data, learning from existing data and generating new data.

Identification AI, on the other hand, focuses on the task of classifying given data and associating it with specific labels or categories. For example, it is good at tasks such as determining whether an image is a dog or a cat.

The two take different algorithmic approaches, with generative AI being better suited for creative tasks, while discriminative AI is better at classification and prediction tasks.

Five types of generative AI

Generative AI can generate information and content in various media formats. We will introduce the main ways to use the following five methods.

  1. Sentence generation
  2. Image generation
  3. Video generation
  4. Data completion
  5. 3D model generation

・Sentence generation

You can summarize and translate texts, change the style of texts, write novels, generate poems, generate news articles, and more.

・Image generation

You can automatically generate illustrations, compose landscapes, repair photos, change facial expressions, convert styles, etc.

・Video generation

Automatically generate animations, add special effects to your movies, repair frames, change the style of your footage, and more.

・Data completion

It can complement missing data or missing information, such as missing data prediction, image restoration, and audio denoising.

・3D model generation

You can generate objects, buildings, characters, 3D printing models, etc.

Benefits of generative AI

Companies can benefit from a variety of benefits by using generative AI. For example, in marketing and content creation, generative AI can be used to quickly generate high-quality content. In today’s business environment, where it is necessary to create and disseminate a variety of content on a daily basis, such as advertisements, blog articles, and SNS posts, making good use of generative AI can greatly save time and effort, making work more efficient. You can.

Generative AI also has the ability to suggest new ideas and designs. This will encourage the development of new products and services, encourage innovation within the industry and, in turn, stimulate more creativity among employees.

Furthermore, by utilizing generative AI to provide customized content and suggestions, it may be possible to provide information and services that match customers’ needs and preferences. This will also improve the customer experience.

Procedures for using generative AI

Although detailed usage methods differ depending on the tools and products used, we will introduce the basic flow of using generative AI.

1. Decide what you want to generate.

First, decide what kind of content you want to generate, such as text, images, videos, and audio.

2. Choose a tool

Choose the appropriate tool depending on what you want to generate. For example, there is “ChatGPT” for text generation, and “Stable Diffusion” for image generation. Please refer to the following chapters, which introduce recommended tools for each type of product.

3. Input data and generate

Generate content and information by entering data such as instructions called prompts. It is not always possible to create an ideal result by entering data once. In that case, experiment with the data input to get the desired product. By doing so, the AI ​​will be trained to produce better results.

Free and paid tools that can use generation AI

From here, we will introduce tools that can actually use generative AI. We have selected recommended tools that can generate highly versatile texts, images/illustrations, videos, and audio in various business and other situations. Most of them are free to use, so please try them out and use them for your business.
