Transformers in AI, Black Box Models, AGI, and Empirical AI Experience

Introduction

Artificial intelligence is developing at an extremely fast pace. Modern AI systems can write text, generate code, analyze documents, create images, process data, support sales teams, automate customer service, and assist with business operations. But as AI becomes more powerful, more people ask important questions: How does AI work? What is a transformer? Why is AI often called a black box? Is AGI possible? Can artificial intelligence gain new empirical experience instead of only relying on its training data?

To understand the future of artificial intelligence, it is not enough to know popular terms such as ChatGPT, LLM, neural network, machine learning, generative AI, RAG, AI agents, and deep learning. It is also important to understand the core concepts behind modern AI systems.

The main idea is simple: modern language models are already powerful cognitive tools, but a more complete form of artificial intelligence will require more than pretraining on large datasets. It will need memory, tools, feedback, interaction with the world, and the ability to learn from consequences.

What Is a Transformer in Artificial Intelligence?

A transformer is a neural network architecture that powers most modern large language models. Transformers are used in AI systems for text generation, code generation, translation, document analysis, semantic search, multimodal AI, and intelligent assistants.

The transformer architecture changed the direction of artificial intelligence because it made it possible to process sequences of data more effectively. These sequences can be text, code, audio, images, video, or structured data.

In simple terms, a transformer is a system that can look at the entire context and decide which parts of the input are important to each other.

For example, in the sentence:

> The bank raised interest rates.

the word “bank” refers to a financial institution. But in another sentence:

> We sat near the bank of the river.

the meaning is different. To understand the correct meaning, the model must analyze context. Transformers do this through a mechanism called attention.

Attention Mechanism: The Core Idea Behind Transformers

The most important part of the transformer architecture is self-attention. Self-attention allows each token to look at other tokens and decide which ones are relevant.

Tokens are the units of text that a model processes. They can be words, parts of words, symbols, or pieces of code. For example, the phrase “artificial intelligence” may be split into several tokens depending on the tokenizer.

A transformer does not read text like a human reading line by line. It converts tokens into numerical vectors and analyzes relationships between them. Inside the attention mechanism, three key representations are used:

• Query — what the current token is looking for;
• Key — what other tokens contain;
• Value — what information can be taken from other tokens.

This is why a modern language model can understand references, follow instructions, detect important context, analyze code dependencies, and generate coherent responses.

Why Transformers Became a Breakthrough

Before transformers, many natural language processing systems used RNNs and LSTMs. These models processed text sequentially, one word at a time. Their main weakness was long-range dependency. The longer the text, the harder it became to preserve important information from earlier parts of the sequence.

Transformers improved this significantly. They can:

• process long context more effectively;
• detect relationships between distant parts of text;
• train efficiently on GPUs;
• scale to very large models;
• work with text, code, images, audio, and video;
• support powerful generative AI systems.

This is why modern large language models, AI assistants, coding tools, search systems, and autonomous AI agents are usually based on transformer-like architectures.

How GPT and Large Language Models Generate Answers

A large language model does not store answers like a traditional database. It works differently.

A simplified process looks like this:

1. The user enters a prompt.
2. The text is split into tokens.
3. Tokens are converted into numerical vectors.
4. The transformer analyzes relationships between tokens using attention.
5. The model estimates the probability of the next token.
6. It generates the next token.
7. The process repeats until the full answer is complete.

This means that an LLM generates text one token at a time. But it is not a simple autocomplete system. Inside the model, there are massive statistical, linguistic, technical, cultural, and logical patterns learned from training data.

That is why AI can write code, explain complex concepts, analyze contracts, create SEO articles, help with software architecture, and hold conversations.

What Is the Black Box Concept in AI?

The black box problem in AI means that we can see the input and the output, but we cannot always fully explain why the model produced a specific answer.

For example:

Input: “Why is the customer not buying?” Output: “The issue may be weak value communication and the absence of a clear next step.”

The answer may be useful and correct. But if we ask why the model chose that specific explanation, we may not be able to reconstruct the exact internal reasoning process.

This is the black box problem: the model works through billions of parameters, vectors, attention layers, probabilities, and complex matrix operations. We understand the general architecture, but we cannot always translate a specific output into a simple human-readable rule.

Why Nobody Fully Knows Why AI Gives a Specific Answer

A traditional program works with explicit rules:

> if the price is higher than 1000, offer a discount; > if the customer says “too expensive,” explain the value.

In that kind of system, it is easy to understand why the output happened. The rule is visible.

A neural network works differently. It does not contain a simple internal rule like:

> if the user asks about AGI, answer this exact way.

Knowledge in a neural network is distributed across billions of parameters. A single fact, skill, or pattern can be spread across many weights. This makes it difficult to open the model and find a clean human-readable explanation.

When an AI system explains its answer, it often generates a post-hoc explanation. That explanation may be logical and useful, but it is not always the true internal cause of the response.

In other words, a model can say:

> I answered this way because the prompt contained certain signals.

But technically, the model is not exposing the full internal computation path. It is generating a plausible explanation after the fact.

A Black Box Does Not Mean AI Is Completely Unknowable

It is important to be precise. Artificial intelligence is not completely mysterious. Researchers understand many important aspects of AI systems:

• transformer architecture;
• attention mechanisms;
• token prediction;
• loss functions;
• embeddings;
• fine-tuning;
• RAG systems;
• AI agents;
• training pipelines;
• evaluation methods.

But there is a difference between understanding the general system and fully explaining every single answer.

Researchers use many methods to study neural networks:

• attention analysis;
• probing;
• activation patching;
• mechanistic interpretability;
• model evaluation;
• prompt variation tests;
• input-output auditing;
• logging AI agent actions.

These techniques help us understand model behavior, but they do not yet provide perfect transparency for every decision.

Why the Black Box Problem Matters

In a casual chat, the black box problem is not always critical. If a user asks for an explanation, a summary, or an article, the output can be checked for quality, usefulness, and factual accuracy.

But in high-stakes areas, AI opacity becomes a serious issue:

• medicine;
• law;
• finance;
• credit scoring;
• hiring;
• government decisions;
• cybersecurity;
• autonomous AI agents;
• business processes with financial consequences.

If AI rejects a loan application, evaluates a medical risk, selects a job candidate, or changes a sales strategy, people need to know: what was the decision based on?

This is why business AI systems need sources, constraints, logs, tests, and human oversight.

How the Black Box Problem Is Reduced in Practice

The black box problem is not fully solved, but it can be reduced through system design.

RAG

RAG, or Retrieval-Augmented Generation, allows a model to answer using specific external documents rather than relying only on internal training data.

For example, an AI support assistant can answer based on a company knowledge base, documentation, policies, FAQs, and customer history.

Citations and Sources

When the model must cite specific documents, it becomes easier to verify where the information came from.

Structured Output

The model can be required to return information in a strict format: JSON, tables, classification labels, CRM fields, or checklists.

Logging

A reliable AI system should log prompts, answers, documents, model versions, timestamps, users, actions, and outcomes.

Human-in-the-Loop

Important decisions should be reviewed by a human. AI can suggest actions, but it should not always execute them automatically.

Rules Above the Model

Business systems often add explicit rules on top of the AI model:

• do not offer a discount above 10%;
• do not change contract terms;
• do not give legal advice without review;
• do not delete data without confirmation;
• do not answer without a source.

This is how more reliable AI systems are built.

Is AGI Theoretically Possible?

AGI, or Artificial General Intelligence, usually means an AI system that can perform a wide range of intellectual tasks at the level of a human or beyond.

In theory, AGI is possible. There is no known physical law that prevents the creation of artificial systems with human-level intelligence.

The argument is straightforward: human intelligence already exists as a physical process. The brain works through biology, chemistry, electrical signals, memory, learning, and interaction with the world. If nature created intelligence from matter, then it is reasonable to believe that artificial systems could reproduce or exceed many intellectual functions.

However, theoretical possibility does not mean we already know exactly how to build AGI.

Why Modern LLMs Are Not Full AGI Yet

Modern large language models can already do many impressive things:

• write text;
• generate code;
• analyze data;
• translate languages;
• help with SEO;
• build business logic;
• analyze documents;
• assist with software development;
• use tools;
• support sales and customer service.

But they are still not full AGI in the strict sense.

Current language models have limitations:

• no stable built-in long-term memory without an external system;
• no autonomous life in the real world;
• no continuous learning from every experience;
• no human body or sensory experience;
• risk of hallucinations;
• dependence on context;
• weak causal grounding compared to humans;
• no stable autonomous motivation;
• no guaranteed understanding of action consequences.

An LLM is a powerful cognitive and language component. But a static transformer by itself is not yet a complete artificial general intelligence.

What a More Complete AI System Would Need

A realistic path to AGI is probably not one giant model alone. It is more likely to be a complex AI system made of several components.

1. A Multimodal Foundation Model

The system should understand text, code, images, audio, video, documents, interfaces, and structured data.

2. Long-Term Memory

AI should remember important events, decisions, mistakes, goals, preferences, outcomes, and learned experience.

3. Tools

A capable AI agent should use browsers, APIs, calendars, email, CRM systems, databases, terminals, file systems, robots, or other external tools.

4. Planning

AI should be able to define a goal, break it into steps, monitor progress, and change strategy.

5. Feedback

The system must know whether an action worked or failed. For example:

• a customer bought or rejected an offer;
• code passed tests or failed;
• an ad campaign generated leads or wasted budget;
• an email received a reply or was ignored;
• a hypothesis was confirmed or disproven.

6. Learning from Experience

Without new experience, AI remains limited. A more complete intelligence must not only use old data but also adjust behavior based on new observations.

How Can AI Gain New Empirical Experience?

Empirical experience is not just information from a book or a database. It is a cycle:

> action → result → observation → conclusion → behavior change.

Humans learn this way. We act, make mistakes, observe consequences, remember outcomes, and change strategy.

AI can gain a similar type of experience if it has access to actions and feedback.

For example, an AI sales agent:

1. Receives a lead from a CRM system.
2. Sends a message to the customer.
3. Checks whether the customer responded.
4. Analyzes which script worked.
5. Stores successful patterns.
6. Changes the next message strategy.
7. Tests a new hypothesis with future customers.
8. Sends uncertain cases to a human manager.

This is more than text generation. It is a learning cycle based on interaction with reality.

Context, Memory, RAG, and Learning: What Is the Difference?

It is important to separate several levels.

Context

Context is the information the model sees right now. For example, the user provides a document, a conversation history, or an instruction.

Context is temporary. If it is not saved, the model may lose that information after the session ends.

Long-Term Memory

Memory allows the system to store important facts and use them later. For example:

> This customer already asked about price. > The user prefers a business style. > This message type works better in sales. > This coding error appeared before.

This is closer to experience, but it does not necessarily change the model weights.

RAG

RAG gives the model access to external knowledge: documentation, policies, databases, CRM data, articles, contracts, and instructions.

RAG is not full learning. It is more like an intelligent library that the model can search before answering.

Fine-Tuning

Fine-tuning trains a model on specialized data. It can embed new skills, behavior, domain knowledge, or writing style more deeply into the model.

Continual Learning

Continual learning means ongoing training on new data. This is closer to living learning, but it is technically difficult. The model can forget older skills, absorb bad data, or become harder to control.

Reinforcement Learning

Reinforcement learning is learning through rewards. The system takes an action and receives a signal: good or bad.

For example:

• code passes tests — positive reward;
• customer buys — positive reward;
• answer is wrong — negative reward;
• action violates a rule — negative reward.

This is an important path toward more autonomous AI systems.

Why Training Data Alone Is Not Enough

If AI is trained once and then only generates answers, it is not a complete intelligence in the strong sense. It is a powerful model of language, knowledge, and patterns.

A more complete intelligence requires:

• interaction with the world;
• new data;
• memory;
• consequence analysis;
• error correction;
• feedback-based learning;
• strategy changes;
• hypothesis testing.

This is why the future of AI is not only about larger language models. It is also about AI agents, RAG systems, autonomous tools, robotics, simulations, multimodal models, and continuous learning systems.

Can AI Have Experience Without a Body?

Humans gain experience through the body: vision, hearing, movement, pain, fatigue, social response, emotions, and consequences.

AI does not necessarily need a human body to gain experience. But it does need a channel for interaction with the world.

That channel can be:

• a browser;
• a CRM system;
• APIs;
• a terminal;
• sensors;
• a robot;
• a simulator;
• a game environment;
• a business system;
• a database;
• customer conversations;
• automated tests;
• financial metrics.

For example, an AI developer gains experience through tests, compiler errors, pull requests, and application behavior. An AI sales agent gains experience through customer responses, conversion rates, objections, and closed deals. An AI analyst gains experience through forecasts, real-world data, and model correction.

So empirical experience in AI does not always require a physical body. It requires action, feedback, memory, and adaptation.

LLMs, AI Agents, and the Path Toward AGI

A simple way to summarize it:

An LLM alone is not AGI. But an LLM combined with memory, tools, planning, RAG, feedback, and learning can become the foundation of an AGI-like system.

The formula looks like this:

> LLM + memory + tools + actions + feedback + learning + planning = a path toward more complete AI.

This does not guarantee AGI, but it makes the system much closer to intelligent behavior.

How Full AI Differs from a Regular Neural Network

A regular neural network:

• receives a prompt;
• analyzes context;
• generates an answer;
• stops.

A more complete AI system:

• understands the task;
• builds a plan;
• uses tools;
• acts in the external world;
• observes the result;
• analyzes consequences;
• stores experience;
• changes strategy;
• checks itself;
• improves future decisions.

This distinction is central to understanding AGI and the future of artificial intelligence.

Practical Business Applications

Even without full AGI, companies can already build powerful AI systems.

AI Sales Agent

AI processes leads, manages conversations, qualifies customers, uses CRM data, remembers history, analyzes conversion, and escalates complex cases to human managers.

AI Customer Support

AI answers customers based on a knowledge base, documentation, FAQs, policies, and conversation history.

AI Developer

AI analyzes code, writes functions, fixes bugs, runs tests, reads documentation, and suggests architecture improvements.

AI Analyst

AI collects data, creates reports, analyzes metrics, detects anomalies, and suggests business hypotheses.

AI Assistant for Companies

AI works with email, calendar, tasks, documents, CRM systems, and internal knowledge bases.

In all these systems, RAG, logs, constraints, sources, human review, and controlled tool use are essential.

Main Risks of More Autonomous AI

The more autonomous AI becomes, the more important control becomes.

Key risks include:

• hallucinations;
• incorrect conclusions;
• confident mistakes;
• hidden bias;
• lack of transparency;
• poorly defined goals;
• bad feedback loops;
• polluted memory;
• uncontrolled behavior changes;
• actions without human confirmation.

This is why AI development should not focus only on making models larger. It should also focus on better architecture, interpretability, governance, data quality, memory design, and safety controls.

Conclusion

Transformers made modern generative AI possible. The attention mechanism allowed models to understand context, detect relationships between words, generate code, analyze documents, and produce complex answers.

But modern neural networks remain partially black box systems. We understand their architecture, but we cannot always fully explain why a model produced a specific answer.

AGI is theoretically possible because human intelligence already exists as a physical process. However, current LLMs are not full AGI. They are powerful foundations, but a more complete AI system requires memory, tools, planning, feedback, empirical experience, and interaction with the world.

The key conclusion is this: the future of artificial intelligence is not just a larger model trained once on more data. It is an agentic system that can act, observe results, remember consequences, learn from feedback, and improve its behavior over time.
