TL;DR
Thorsten Meyer’s ‘Inside AI II’ series unveils twelve detailed machines behind AI language models, explaining how they process, understand, and generate text. This article explores each machine’s role and significance.
Thorsten Meyer’s ‘Inside AI II’ series has introduced twelve detailed machines that reveal the inner workings of AI language models, making complex processes accessible and explorable directly in your browser.
This development offers a transparent look at how chatbots process language, why they behave as they do, and what makes modern AI systems powerful, all without requiring sign-up or data tracking.
The series breaks down the core components of AI language models into twelve distinct ‘machines’, each representing a fundamental process in how AI interprets and generates text. These include the tokenization process, the creation of word embeddings, the attention mechanism, and the handling of model parameters, among others.
Each machine is explained through practical, interactive examples that users can run themselves in their browsers. For instance, users can see how tokens are created from text, how words are mapped onto a conceptual space, and how the AI determines the meaning of ambiguous words like ‘it’ based on context.
Thorsten Meyer emphasizes that these machines operate at different stages—some handle raw data, others interpret meaning, and some optimize the model’s guesses—showing how they work together to produce coherent responses.
Notably, the series clarifies that real-world AI systems involve dozens or hundreds of such stages, often running billions of calculations simultaneously, which is far more complex than the simplified models often described publicly.
The tools are designed to be accessible, allowing users to observe the step-by-step process of AI inference, from chopping text into tokens to adjusting model parameters during training or inference, providing a hands-on understanding of AI’s operational core.
While these machines are explained in detail, the series also acknowledges what remains uncertain—such as the full complexity of large models and the nuances of how they generalize from training data to unseen inputs.

The Inner Workings of AI II: Twelve Machines in Detail
Thorsten Meyer’s “Inside AI II” series turns the hidden steps behind AI language models into a set of practical, explorable machines—from text tokenization to the calculations that shape a response.
01 / Why it matters
Make the black box easier to inspect
A guided view of common model mechanisms can support clearer conversations about capability, limits, and safety.
Language models can feel opaque: a prompt goes in, a fluent answer comes out, and the steps in between are easy to miss. “Inside AI II” breaks those steps into twelve distinct machines that visitors can run and observe in a browser.
Examples show how text becomes tokens, how words map into conceptual space, and how context helps resolve an ambiguous word such as “it.” The aim is to make ideas that are usually buried in technical descriptions tangible.
That practical view can help readers and developers reason about how chatbots behave, where biases or weaknesses might appear, and why transparency matters for responsible AI.
At a glance
From input to a likely next word
The machines represent different jobs in a model: handling raw text, building representations, using context, and adjusting or applying learned parameters. Together, these stages help produce a coherent response.
02 / The machine set
Twelve views into a shared process
The article names examples of core mechanisms; the cards below group the concepts it describes into a readable map.
Tokenization
Breaks text into smaller units a model can process, such as words, word pieces, or punctuation.
Word embeddings
Maps tokens into numerical vectors that place related language in a learned conceptual space.
Attention
Connects parts of a sequence so the model can weigh relevant context when interpreting a token.
Model parameters
Stores learned numerical settings that shape the model’s behavior and predictions.
Context resolution
Shows how surrounding words can change what an ambiguous term such as “it” refers to.
Next-token choice
Uses the current representation to estimate which token may sensibly come next.
Parameter updates
Illustrates how model settings can be adjusted during learning to improve predictions.
Forward computation
Applies learned settings to new input, carrying information through successive operations.
Parallel calculations
Highlights how many operations can run together across large models and sequences.
Text generation
Turns model predictions into a sequence of tokens that can be read as a response.
Layered processing
Emphasizes that distinct mechanisms contribute at different points in model behavior.
Generalization
Raises the open question of how learned patterns extend to inputs the model has not seen.
03 / A simplified journey
How a prompt becomes a response
A compact map of the ideas the series makes visible. Production systems include many more operations.
Split into tokens
Convert the prompt into units the model can handle.
Build vectors
Map tokens into numerical representations.
Use context
Attention connects relevant parts of the input.
Apply parameters
Learned values shape the model’s next prediction.
Choose output
Predicted tokens are assembled into a response.
04 / What the model leaves open
Useful simplifications, real unknowns
Interactive explanations offer a foothold. They do not reveal every detail of a large deployed system.
What the series helps show
Mechanisms you can inspect
Browser-based examples make tokenization, embeddings, attention, and parameters easier to explore step by step. Many modern language models share these broad ideas, though implementations differ.
What remains difficult
Scale, bias, and generalization
Large systems involve many interacting stages and vast numbers of calculations. How they generalize, handle bias, and behave on unfamiliar inputs remains an active area of research.
The visualizations intentionally simplify some processes for accessibility; commercial systems can include additional layers and edge cases beyond what a small interactive model can capture.
05 / Questions readers ask
Exploring the machines
A few practical takeaways for anyone beginning to study language models.
How can I explore them?
Visit Thorsten Meyer’s “Inside AI II” browser-based platform to run and observe the machines, without sign-up or tracking as described in the article.
Do the ideas apply to every chatbot?
Many modern language models use related core processes, including tokenization, embeddings, and attention. Their specific designs and implementations vary.
What is hardest to understand?
Researchers are still working to understand how large models generalize, represent bias, and respond to inputs outside their training experience.

Simplified Breakdown of Complex AI Machinery
Thorsten Meyer’s ‘Inside AI II’ builds on the first part of the series, which introduced foundational questions about AI, by offering detailed insights into the specific mechanisms that power language models. The series aligns with ongoing efforts in AI transparency and explainability, which aim to make AI systems more understandable and trustworthy.
Historically, AI models have been considered ‘black boxes,’ with their internal processes hidden from users. This series aims to change that by providing concrete, explorable examples of how tokens, embeddings, attention, and parameters work together.
It also responds to the growing public and technical interest in understanding AI’s inner workings, especially as models grow larger and more complex, with billions or trillions of parameters.
These developments come amid broader conversations about AI safety, bias, and regulation, making the series a timely educational resource.
“Our series aims to make the complex machinery of AI accessible and explorable, so everyone can see how chatbots really work.”

Limitations and Unanswered Questions in AI Mechanics
While the series offers detailed explanations of twelve core machines, it acknowledges that the full complexity of large-scale models—especially those with trillions of parameters—is still not fully understood. The exact ways in which these models generalize, handle bias, or adapt to new data remain areas of active research.
Additionally, the series simplifies some processes for accessibility, so some nuances and edge cases are not fully explored. The real operation of commercial, production-level AI systems involves additional layers of complexity that are not yet fully explained or visualized.
It is also not yet clear how these insights will influence future AI design or regulation, though the series aims to foster better understanding and discussion.
