Artificial Intelligence models – what are they, how do they work, and what applications do they have in business?

When people hear the phrase “Artificial Intelligence models,” most think of ready-made solutions such as ChatGPT, Claude, and similar tools. In reality, however, models are mathematical structures that analyze data and, based on it, make decisions or generate content. AI models are the foundation of the entire Artificial Intelligence ecosystem.

So let’s explain what AI models are, how they are created, what types exist, and why manufacturing companies, banks, and retail chains are increasingly deciding to implement them. We will also take a closer look at the limitations and risks associated with Artificial Intelligence models.

What is an AI Model?

Let’s start with the basics, because terminology in this area can often be confusing.

An algorithm is essentially a recipe – a set of rules and instructions describing how to solve a specific problem. By itself, it does not “know” anything and does not “make decisions.” Only when an algorithm is applied to data and, as a result of this process, creates a mathematical representation of relationships, do we refer to it as an AI model.

A simple example: a linear regression algorithm is a method. A sales forecasting model built on historical data from a manufacturing company is already a model. It contains “learned” relationships, such as: sales increase on Fridays, decrease in August, and a promotion on a specific product generates a certain increase in volume.

An AI system is something broader – an application or platform that uses one or more models, integrates them with operational data, user interfaces, and other components in order to deliver business value.

In practice, a model is only one element of the pipeline – alongside data processing, feature engineering, and decision logic, which together form a complete AI system.

Types of AI Models

AI models differ in purpose, architecture, and the types of problems they solve. For the purposes of this article, we discuss two fundamental categories that are most important for business – omitting, among others, anomaly detection models or decision optimization models.

Predictive Models (Predictive AI)

Their role is to predict the future based on historical data. They forecast, classify risk, assign scores, or categorize data. Typical applications include:

• demand forecasting – predicting how many units of a given product will be sold in the coming week or month,
• Predictive Maintenance – estimating the probability of machine failure before it occurs,
• credit scoring – assessing a customer’s creditworthiness based on their financial history.

Predictive models are currently one of the most mature and proven areas of AI in business.

Generative Models (Generative AI)

This is the newest, but also the most high-profile category. Generative models do not only analyze data – they create new content: text, images, code, audio, or video. The most important subcategory is LLMs (Large Language Models) – large language models such as GPT-4 or Sonnet (used in Claude), which can conduct conversations, write reports, summarize documents, translate, and generate code.

How are Artificial Intelligence models created?

Regardless of whether we are talking about a predictive or generative model, the development process follows a similar pattern. The scale, infrastructure, and technical details may differ, but the overall logic remains the same. We can distinguish 4 key stages:

• Data collection – in predictive models, these are usually structured data sources: system logs, sensor readings, transaction history, or ERP and MES data. In the case of language models (LLMs), the source consists of enormous collections of text (articles, documents, etc.) counted in billions of words.
• Data preparation – cleaning, normalization, and removing errors and duplicates. This stage can consume up to 60–80% of the entire project time and is common to all model types. The quality of input data directly determines the quality of the model itself, following the principle: “garbage in, garbage out.”
• Model training – the algorithm learns relationships from the prepared data. In predictive models, this usually takes from a few minutes to several days and requires moderate computing power. In the case of large language models, the process can take weeks and involve thousands of GPU processors. That is why companies almost always use pre-trained models instead of building LLMs from scratch.
• Testing and validation – verification using data the model has not seen before. At this stage, we evaluate accuracy, resistance to noise, and the ability to generalize, meaning correct performance in new situations.

Each of these stages is discussed in more detail in our article on ML – read more about what Machine Learning is and why it determines the success of an AI project.

AI Models in business – examples of applications

Even at a theoretical level, it is clear how many business applications Artificial Intelligence models can have. Let’s look at selected examples of their use and the value they deliver across different industries.

Retail: demand forecasting and inventory optimization

Retail chains have struggled with the same problem for years: too little stock means lost sales, while too much stock leads to warehousing and spoilage costs. Predictive models analyze historical data, seasonality, promotions, and even weather forecasts to deliver more accurate demand predictions. The results we have achieved with our retail clients include a significant reduction in out-of-stock situations and lower excess inventory levels – while simultaneously improving product availability for end customers.

Banking: fraud detection and scoring

In the financial sector, AI models operate on two fronts. First – fraud detection in real time: the model quickly and efficiently analyzes transactions and flags those that deviate from a customer’s typical behavior patterns. Second – credit scoring, which takes into account far more variables than traditional methods, allowing for a more accurate assessment of actual risk.

Manufacturing: Predictive Maintenance

This is one of the areas where AI probably has the greatest direct impact on operational performance. Predictive models, powered by data from sensors and SCADA systems, can predict failures of specific machines days or even weeks in advance.

Instead of repairing equipment after a failure occurs (which generates costly downtime) or replacing components according to a fixed schedule (which often leads to waste), companies move toward maintenance based on the actual condition of machines. This represents a shift from reactive to proactive operations – and it is exactly in manufacturing environments where AI demonstrates its value most clearly.

Customer service: chatbots and voicebots

Language models now power chatbots and voicebots that handle the first line of customer interaction – answering standard questions, classifying requests, and forwarding more complex cases to consultants. In a well-designed system, such assistants can resolve a significant portion of inquiries without human involvement, shortening service times and reducing the workload on teams.

How do companies implement AI models in practice?

The technology itself is only part of the success. In practice, implementing an AI model is simultaneously an integration, infrastructure, and organizational challenge.

• System integration – often the most difficult element. The model must have access to real-time or near-real-time data – and in manufacturing companies, data may exist across dozens of systems and sources: ERP, MES, SCADA, WMS, spreadsheets, and more. Before an AI model can start working, companies must ensure that data is consistent, up to date, and available in one place. That is why more and more AI projects begin with building a data environment rather than the model itself.
• Infrastructure – another strategic decision. Companies usually choose between three approaches:
  • Cloud – quick deployment, scalability, and low entry barriers. Suitable for prototyping and applications where data can leave the organization.On-premises – full control over data, crucial where security or regulatory requirements prevent transferring data to external servers. Increasingly chosen by manufacturing companies and regulated industries.Hybrid – combines both approaches. Sensitive data remains local, while less critical computations can be moved to the cloud.
• Model management (MLOps) – an area often underestimated during planning. A deployed model does not operate independently forever. Data changes over time: sales patterns evolve, new product ranges appear, machinery changes. Models require monitoring, retraining, and updates. Without this, their effectiveness gradually declines – often imperceptibly at first, which makes the problem particularly dangerous.

Limitations and risks of AI models – what should not be ignored?

This discussion is essential, especially when talking about deployments in manufacturing, finance, or healthcare environments, where model errors can have real consequences.

Hallucinations in language models

Generative models, especially LLMs, tend to generate content that sounds convincing but is actually false. This phenomenon is known as hallucination. The model does not “lie” in the human sense – it simply generates statistically probable sequences of tokens without any native, built-in fact-verification mechanism.

In practice, this means that an LLM may:

• reference non-existent research studies or legal regulations,
• provide incorrect numerical data with high confidence,
• generate code that appears correct but contains subtle errors.

How can the risk be reduced? Do not deploy LLMs in processes where incorrect information may have serious consequences without human supervision. It is also worth using techniques such as RAG (Retrieval-Augmented Generation), which ground the model’s responses in verified internal company documents – significantly reducing the risk of hallucinations.

Errors in Predictive Models

Predictive and classification models also make mistakes, and this must be accepted as an inherent characteristic. No model achieves 100% accuracy. The key issue is understanding what level of error is acceptable in a given business process and how the model behaves in edge cases it did not encounter during training.

A particularly important risk is so-called data drift – a situation in which reality starts to differ from the data on which the model was trained. For example, a demand forecasting model trained on pre-pandemic data may simply fail to handle new purchasing patterns.

How can the risk be reduced? Regular monitoring of model metrics in production environments, alerts when quality decreases, and scheduled retraining.

Bias – model bias and fairness issues

Models learn from historical data. If this data contains bias – and it often does, because it reflects human decisions – the model absorbs and amplifies those biases. In a business context, this may result in credit scoring systems discriminating against certain customer groups, HR systems favoring specific candidate profiles, or quality models performing worse for products from new suppliers.

How can the risk be reduced? Auditing training data, consciously designing training datasets, testing models across different groups and scenarios, and – in regulated areas – implementing Explainable AI (XAI) principles that help explain why a model made a specific decision.

We discuss Explainable AI and how to transform the “black box” into a trustworthy tool in our article Artificial Intelligence with an Instruction Manual.

Awareness of AI model limitations is not a reason to avoid implementation. It is a prerequisite for responsible and effective adoption. Companies that understand these risks can manage them and gain real business value from AI instead of learning through costly mistakes.

AI models are the mathematical core of modern Artificial Intelligence systems. They are not magic. They are tools. Like any tool, they work well when properly matched to the task, built on solid data, and correctly implemented within the company’s operational environment.

Key takeaways

• AI models learn from data and, based on it, predict or generate outputs. The better the quality of the data and training process, the more effective the model.
• Different types of models address different needs: predictive models are used for forecasting and maintenance, while generative models are designed for language, knowledge, and content creation tasks.
• AI implementation is not a one-time project – it is a continuous process of monitoring, updating, and integrating with the company’s evolving IT environment.
• The limitations are real: hallucinations, drift, and bias – organizations must understand and actively mitigate them.
