Artificial intelligence (AI) technology has created opportunities to progress on real-world problems concerning health, education, and the environment. In some cases, artificial intelligence can do things more efficiently or methodically than human intelligence.聽

鈥淪mart鈥� buildings, vehicles, and other technologies can decrease carbon emissions and support people with disabilities. Machine learning, a subset of AI, has enabled engineers to build robots and self-driving cars, recognize speech and images, and forecast market trends.聽

Read on to learn more about the four main types of AI鈥攔eactive machines, limited memory machines, theory of mind, and self-awareness鈥攁nd their functions in everyday life.

4 main types of artificial intelligence

Learning in AI can fall under the types 鈥渘arrow intelligence,鈥� 鈥渁rtificial general intelligence,鈥� and 鈥渟uper AI.鈥� These categories demonstrate AI鈥檚 capabilities as it evolves鈥攑erforming narrowly defined sets of tasks, simulating thought processes in the human mind, and performing beyond human capability.

Watch this video from IBM's Introduction to Artificial Intelligence (AI) course to learn more about these categories:

There are four main types of AI as defined by Arend Hintze, researcher and professor of integrative biology at Michigan State University []. They are as follows:

1. Reactive machines

Reactive machines are AI systems that have no memory and are task-specific, meaning that an input always delivers the same output. Machine learning models tend to be reactive machines because they take customer data, such as purchase or search history, and use it to deliver recommendations to the same customers. 聽

This type of AI is reactive. It performs 鈥渟uper鈥� AI because the average human would not be able to process huge amounts of data, such as a customer鈥檚 entire Netflix history and feedback customized recommendations. Reactive AI, for the most part, is reliable and works well in inventions like self-driving cars. It doesn鈥檛 have the ability to predict future outcomes unless it has been fed the appropriate information.

Compare this to our human lives, where most of our actions are not reactive because we don鈥檛 have all the information we need to react upon, but we have the capability to remember and learn. Based on those successes or failures, we may act differently in the future if faced with a similar situation.

Examples of reactive machines

Beat at chess by IBM鈥檚 supercomputer: One of the best examples of reactive AI is when Deep Blue, IBM鈥檚 chess-playing AI system, beat Garry Kasparov in the late 1990s. Deep Blue could identify its own and its opponent鈥檚 pieces on the chessboard to make predictions, but it does not have the memory capacity to use past mistakes to inform future decisions. It only makes predictions based on what moves could be next for both players and selects the best move.聽

Netflix recommendations: Netflix鈥檚 recommendation engine is powered by machine learning models that process the data collected from a customer鈥檚 viewing history to determine specific movies and TV shows that they will enjoy. Humans are creatures of habit鈥攊f someone tends to watch a lot of Korean dramas, Netflix will show a preview of new releases on the home page.

2. Limited memory machines

The next type of AI in its evolution is limited memory. This algorithm imitates the way our brains鈥� neurons work together, meaning that it gets smarter as it receives more data to train on. Deep learning algorithms improve natural language processing (NLP), image recognition, and other types of reinforcement learning.

Limited memory AI, unlike reactive machines, can look into the past and monitor specific objects or situations over time. Then, these observations are programmed into the AI so that its actions can be performed based on both past and present moment data. But in limited memory, this data isn鈥檛 saved into the AI鈥檚 memory as experience to learn from, the way humans might derive meaning from their successes and failures. The AI improves over time as it鈥檚 trained on more data.

Example of limited memory artificial intelligence

Self-driving cars: A good example of limited memory AI is the way self-driving cars observe other cars on the road for their speed, direction, and proximity. This information is programmed as the car鈥檚 representation of the world, such as knowing traffic lights, signs, curves, and bumps in the road. The data helps the car decide when to change lanes so that it does not get hit or cut off by another driver.聽

3. Theory of mind

The first two types of AI, reactive machines and limited memory, are types that currently exist. Theory of mind and self-aware AI are theoretical types that could be built in the future. As such, there aren鈥檛 any real-world examples yet.

If it is developed, theory of mind AI could have the potential to understand the world and how other entities have thoughts and emotions. In turn, this affects how they behave in relation to those around them.

Human cognitive abilities are capable of processing how our own thoughts and emotions affect others and how others鈥� affect us鈥攖his is the basis of our society鈥檚 human relationships. In the future, theory of mind AI machines could be able to understand intentions and predict behavior, as if to simulate human relationships.

What type of AI is ChatGPT?

ChatGPT is an example of generative AI, a kind of artificial intelligence powered by large language models (LLMs) that are created by training algorithms on massive amounts of data. Generative AI is capable of creating original outputs in response to user inputs or "prompts." ChatGPT's ability to produce responses resembling human language has made it a common type of AI used for chatbots and virtual assistants.

That said, while tools like ChatGPT, Google Gemini, or Microsoft Copilot may produce responses that give the impression of a self-aware AI, they aren't really. Instead, their responses are actually just the result of the algorithm identifying the statistically most likely output based on its training data and the user's prompt.

4. Self-awareness

The grand finale for the evolution of AI would be to design systems that have a sense of self, a conscious understanding of their existence. This type of AI does not exist yet.

This goes a step beyond theory of mind AI and understanding emotions to being aware of themselves, their state of being, and being able to sense or predict others鈥� feelings. For example, 鈥淚鈥檓 hungry鈥� becomes 鈥淚 know I am hungry鈥� or 鈥淚 want to eat lasagna because it鈥檚 my favorite food.鈥澛�

Artificial intelligence and machine learning algorithms are a long way from self-awareness because there is still so much to uncover about the human brain鈥檚 intelligence and how memory, learning, and decision-making work.
