Generative AI vs. Predictive AI: Differences and Applications

Artificial intelligence (AI) is significantly impacting various industries. For example, in health care, AI helps to diagnose disease and speed up drug research. In marketing, professionals use AI to produce content quickly, while business managers leverage it to analyze market trends and make informed decisions.

The two main types of AI driving these changes are generative AI and predictive AI.

Generative AI is designed to respond to natural-language queries with novel, context-specific outputs. This makes the AI tools especially useful for creative tasks or when trying to develop new solutions. In contrast, predictive AI focuses on analyzing historical data. By examining previous data and patterns, AI can make forecasts about future events or trends. This is especially valuable for industries or roles that rely on data-driven predictions.

In this article, we’ll explore the differences between generative AI and predictive AI. We’ll explain how each type of AI works and the common situations where they’re used.

What is generative AI?

Generative AI systems use machine learning algorithms to sift through large datasets to identify patterns. Those patterns enable the AI to produce new content based on the user’s request.

One technique for this is the generative adversarial network (GAN), which is primarily used for image generation. In this framework, two neural networks come into play:

• The generator is responsible for crafting images
• The discriminator assesses their authenticity

They engage in a feedback loop, refining the generated content until the discriminator struggles to differentiate between authentic and AI-generated material.

While GANs historically led advances in image generation, diffusion models—such as those used by DALL-E 3 and Midjourney v6—have become the dominant architecture for generating realistic, high-quality images.

Rooted in deep learning, another technique using a transformer model excels in natural language processing (NLP) tasks due to its attention mechanism. This allows the AI to scrutinize all segments of an input simultaneously, enabling swift text analysis and prioritizing relevant sections during output generation.

These advancements have paved the way for a variety of applications. For instance, transformers have led to the emergence of large language models (LLMs) like OpenAI’s ChatGPT, which streamline projects like writing by processing user input to generate coherent text.

Generative AI isn’t just about text and pictures—it can also help in formats like audio and video, and can even help research and content edit by filling in gaps where data is missing, a process called data augmentation. This has huge significance, especially when there’s not enough data to work with.

Generative AI has proven to have use in many industries, from health care where it helps discover new medicines and diagnose patients, to e-commerce where its chatbots interact with customers and write product descriptions.

Generative AI use cases

In this section, we look at some functions of generative AI and explain how generative AI is beneficial.

• Content creation. Generative AI aids creatives and marketers in producing content like blog posts, ad creatives, videos, images, and audio. For example, Writesonic offers text generation abilities, while DALL-E 3 specializes in image generation.
• Customer support. Companies use generative AI models to train chatbots on product details. For example, AI applications like Zendesk’s AI Agents can connect to businesses’ internal data to respond to customer queries.
• Drug discovery. Generative AI accelerates the creation of molecules for drug research, enabling faster discovery of potential drug candidates. For example, Pharma.AI focuses on disease target identification, the generation of novel molecules, and predicting clinical trial outcomes.
• Product design. Generative AI tools help designers transform ideas into functional prototypes to speed up the development process. Vizcom is one platform that transforms product sketches into full renders using AI.
• Synthetic data generation. Instead of using genuine customer data, generative AI creates synthetic data, ensuring privacy during testing and other processes. J.P. Morgan employs this technique to simulate financial scenarios, testing situations like fraud and market events.
