TL;DR
This article explores the 12 core machines that make AI language models function, detailing how each contributes to processing and generating text. It highlights confirmed technical processes and ongoing complexities, offering insights into AI’s inner workings.
Recent disclosures from Thorsten Meyer AI reveal the existence of twelve key machines that form the core of AI language models, such as chatbots. These machines work in concert to process input, interpret meaning, and generate responses, offering a clearer understanding of AI’s internal architecture. This development matters because it breaks down the complex process of AI inference into tangible components, making the technology more accessible and transparent for developers and users alike.
According to Meyer, the AI core engine comprises twelve distinct machines, each responsible for specific stages in the text processing pipeline. These include the tokenization machine, which breaks down input into manageable pieces called tokens; the embedding machine, which maps words onto a high-dimensional space; and the attention machine, which determines the focus on relevant parts of the input. The model also includes multiple layers for pattern recognition, parameter adjustment, and response generation. These machines operate within a framework that allows the AI to handle billions of parameters, enabling nuanced understanding and context retention.
Notably, Meyer emphasizes that these machines run on user devices—such as phones, tablets, or computers—without requiring sign-up, cookies, or tracking. This suggests that the core processing can be decentralized, relying on inference rather than cloud-based training. The process involves sequentially passing data through each machine, with each stage refining the understanding and output based on learned patterns. While the architecture is complex, Meyer’s breakdown offers a practical view of how AI models function at a fundamental level.

AI’s Core Engine: Inside The Twelve Machines That Make It Work
A language model is not one mysterious box. It is a sequence of learned computations that turns tokens into a next-token prediction—and, step by step, a response.
01 / Component map
Twelve roles, one text pipeline
The article frames AI inference as specialized stages working together. It names tokenization, embeddings, and attention, then describes other roles by function. The remaining labels below are functional groupings, not a claim that every model uses twelve separate modules with these exact names.
Tokenization
Splits text into tokens—the units the model can process.
Embeddings
Maps token identities into vectors that encode learned relationships.
Attention
Lets the model weigh relationships among tokens in context.
Pattern recognition
Transformer layers combine signals to build contextual representations.
Parameters
Learned weights shape how information is transformed during inference.
Repeated layers
Multiple blocks refine representations through successive computations.
Sequence position
Position information helps the model account for token order.
Feed-forward processing
Within each layer, learned transformations further process token features.
Residual pathways
Skip connections help information and gradients move through deep networks.
Normalization
Normalization operations help stabilize computations across layers.
Output scoring
Final scores represent candidate next tokens before selection.
Response generation
A decoding strategy selects tokens in sequence to produce text.
02 / How inference unfolds
From prompt to generated text
At a high level, input is represented, repeatedly transformed using learned patterns, then converted into a sequence of output tokens. Each new token can become context for the next prediction.
03 / Why the breakdown matters
A clearer map for builders and users
More useful transparency
Seeing distinct operations can help developers reason about model behavior, diagnose errors, and improve particular parts of a system. It also gives users a more concrete mental model than the “black box” metaphor alone.
Privacy possibilities
Inference can run locally when a device has a compatible model and enough memory and compute. This can reduce dependence on remote servers for some tasks; it is not a guarantee that every chatbot runs entirely on a user’s device.
Accuracy and bias work
Understanding where representations and predictions are formed can support research into reliability and bias. The components interact, so no single stage offers a complete fix.
Not one universal blueprint
Models share broad functions, while their architecture and implementation vary. “Twelve machines” is a helpful explanatory framing, not a standardized inventory used by every AI model.
04 / Open research
What is still being worked out?
A component map makes the process easier to discuss, while important questions remain about interactions, scale, and control.
How does context evolve?
Long, multi-turn conversations raise questions about how information is represented, retained in the context window, and prioritized at each step.
How does the system scale?
Larger models increase demands on compute and memory. Efficient algorithms and hardware remain active areas of development.
How can behavior be controlled?
Researchers continue to study interpretability, safety, and bias mitigation across interacting components and training processes.
05 / Quick answers
Key questions
What are the twelve machines?
They are a way to describe the functions involved in processing text and generating output, including tokenization, embeddings, attention, layered transformations, and response generation.
How does this help AI development?
A clearer functional map can help developers analyze behavior, troubleshoot problems, and communicate how language models work.
Are they identical in every model?
No. Broad functions recur, but implementations and architectures vary by model.
Can inference run on personal devices?
Yes, some models can run locally on phones, tablets, or computers when device resources and software support it.
What remains uncertain?
Dynamic behavior in complex conversations, scaling, interpretability, and safety remain active research topics.
What does “inference” mean?
Inference is the process of using a trained model to make predictions, such as generating the next token in a response.
Implications for AI Transparency and Development
Understanding these twelve core machines enhances transparency in AI development, allowing developers to optimize models and troubleshoot issues more effectively. It also demystifies AI behavior for users, fostering greater trust and informed use. As AI becomes more embedded in daily life, clarity about its inner workings is crucial for ethical deployment and innovation. Additionally, knowing that these machines operate efficiently on user devices opens possibilities for more privacy-conscious AI applications, reducing dependence on centralized servers and data collection.

Technical Foundations of Modern AI Models
The detailed architecture of AI models has evolved rapidly, from simple neural networks to complex systems with billions of parameters. Historically, much of this complexity was opaque, with only high-level descriptions available. Meyer’s series, especially the focus on these twelve machines, provides a granular view of the process, aligning with recent advances in explainable AI. The breakdown reflects a synthesis of current research and practical implementation, emphasizing that modern chatbots are not monolithic but composed of specialized, interacting components.
Prior to this, many experts viewed AI as a ‘black box.’ Now, with clearer mappings of core processes—like tokenization, embeddings, and attention mechanisms—developers can better design, improve, and regulate AI systems. This knowledge also supports efforts to reduce biases and improve response accuracy, as each machine can be fine-tuned independently.
“The twelve machines form the backbone of AI inference, each playing a specific role in transforming input into meaningful output.”
