📚 Types of Large Language Model
When creating an LLM, one needs to understand the various categories of models that exist. Depending on the tasks and functions to be performed, LLMs can be classified into various types. Here, we have considered the principal types of LLMs to assist you in making the right choice.
Autoregressive Language Models
Autoregressive (AR) language models build the next word of a sequence based on preceding words. These models predict the probability of the next word using context, making them suitable for generating large, contextually accurate pieces of text. However, they lack a global view as they process sequentially, either forward or backward, but not both.
Autoregressive models are particularly useful for tasks such as:
- Responding to prompts and creating articles, stories, or other text-intensive content.
- Interpreting language where maintaining context is crucial.
- Autoencoding Language Models
Examples: GPT-3 and GPT-4: GPT-3 and GPT-4 are Generative Pre-trained Transformer models created by OpenAI. They generate human-like text and are used in content generation, language translation, and more.
Autoencoding Language Models
Autoencoding models, like Bidirectional Encoder Representations from Transformers (BERT), aim to reconstruct input from a noisy version. These models predict masked words in a text sequence, enabling them to understand both forward and backward dependencies of words.
Autoencoding models are suitable for:
- Brief text segments such as keywords, questions, or short descriptions (e.g., search queries or product descriptions).
- Tasks requiring extensive context, such as sentiment analysis.
Exploring the different types of Large Language Models, like autoregressive and hybrid models, is essential if you want to build your own LLM tailored to your needs.
(image by Golo)
Example: BERT is a transformer model developed by Google, pretrained on large text corpora, and fine-tuned for tasks like sentiment analysis, named entity recognition, and question answering.
Transformer-Based Models
The field of transformers uses the transformer architecture for input text to parse it into tokens and apply self-attention. Due to this, the model is capable of understanding the relations between tokens, unlike identifying relations between tokens in conventional models.
Example: BERT and GPT models: Both employ the transformer scheme. However, BERT is designed to treat contexts within texts, while GPT models are intended to generate texts corresponding to the given context.
Hybrid Models
There exists a relation between autoregressive models and autoencoding models, with the latter originating from the former as enhanced models. They are supposed to generate textual output from the input and should be able to learn enough to perform specific NLP tasks such as classification, generation, and translation.
Example: T5 (Text-to-Text Transfer Transformer): The next effective model developed by Google is T5, which is universal and effective due to the fact that it uses the idea of transfer learning based on a text-to-text model to complete multiple NLP tasks with high precision.
Hybrid models offer a versatile solution for creating an LLM model that excels in both text generation and contextual understanding.
(image by Conceptzilla)
Hybrid models offer:
- A useful property of generated text that does not contain massive self-copying and does not constantly produce random variations.
- The ability to be adapted in a better way to the particular application or use case, such as chatbots or virtual personal assistants.
Multilingual Models
Multilingual models are created on the basis of various language datasets, enabling them to process and synthesize text in different languages. They are very suitable for cross-lingual IR, multilingual bots, and MT.
Example: XLM (Cross-lingual Language Model): Less than a year old and created by Facebook’s sister company, XLM is intended to handle many languages and all aspects that require input from different cultures.
Deciding on the kind of large language model that suits you best depends on your styles and uses of the tool. Autoregressive models are better for creating high-quality text, like in news articles, while autoencoding models are good for understanding context if the input is shorter. Most current NLP tasks are dominated by a stable architecture built on transformers, and the use of hybrid models provides many opportunities to create versatile and constantly adjustable models.
When the complexity of language structures and algorithms is not very high, then a multilingual model is necessary for the given application. It is hoped that by now you have a clearer idea of the various types of LLMs available so that you can steer clear of some of the difficulties incurred when constructing a private LLM for your companies.
⚙️ Principle of Work and Main Components of LLM
In this section, we asked Stormotions experienced developer Andrian Yarotsky to talk about the principle of work and main components of LLM. Keep reading! 👇
LLMs are artificial neural networks that utilize the transformer architecture, invented in 2017 and described in the article "Attention Is All You Need". Transformer architecture leverages self-attention mechanisms to process input data in parallel, allowing it to capture contextual relationships over long distances more efficiently than traditional sequential models. This architecture, characterized by its encoder-decoder structure, excels in tasks such as natural language processing by modeling dependencies without regard to their position in the input sequence. All transformers share the same fundamental components:
Tokenizers: These convert text into tokens.
Embedding Layer: This single layer transforms tokens and their positions into vector representations.
Transformer Layers: These layers perform repeated transformations on the vector representations, extracting increasingly complex linguistic information. They consist of alternating attention and feedforward layers.
(Optional) Un-embedding Layer: This layer converts the final vector representations back into a probability distribution over the tokens.
Transformer layers come in two types: encoders and decoders. The original Transformer model used both types, but later models typically use only one. For instance, BERT is an encoder-only model, while GPT models are decoder-only.
🛠️ How to Build Your Own LLM Step-by-Step
Building an LLM model from initial data collection to final deployment is a complex and labor-intensive process that involves many steps. Our developer Andrian Yarotsky will provide more details about this.
Define Objectives and Requirements.
Defining objectives and requirements is the first critical step in creating an LLM. It involves determining the specific goals of the model, such as whether it will be used for text generation, translation, summarization, or another task. This stage also includes specifying performance metrics, model size, and deployment requirements to ensure the final product meets the intended use cases and constraints.
Data Collection
Data collection is essential for training an LLM, involving the gathering of large, high-quality datasets from diverse sources like books, websites, and academic papers. This step includes data scraping, cleaning to remove noise and irrelevant content, and ensuring the data's diversity and relevance. Proper dataset preparation is crucial, including splitting data into training, validation, and test sets, and preprocessing text through tokenization and normalization.
Proper dataset preparation ensures the model is trained on clean, diverse, and relevant data for optimal performance.

Model Architecture Design
Model architecture design involves selecting an appropriate neural network structure, such as a Transformer-based model like GPT or BERT, tailored to language processing tasks. It requires defining the model's hyperparameters, including the number of layers, hidden units, learning rate, and batch size, which are critical for optimal performance. This phase also involves planning the model's scalability and efficiency to handle the expected computational load and complexity.
Training the Model
Training the model is a resource-intensive process that requires setting up a robust computational infrastructure, an essential aspect of how to build LLM, often involving GPUs or TPUs. The training loop includes forward propagation, loss calculation, backpropagation, and optimization, all monitored through metrics like loss, accuracy, and perplexity. Continuous monitoring and adjustment during this phase are crucial to ensure the model learns effectively from the data without overfitting.

Fine-tuning and Optimization
Fine-tuning and optimization are performed to adapt a pre-trained model to specific tasks or domains and to enhance its performance. Transfer learning techniques are used to refine the model using domain-specific data, while optimization methods like knowledge distillation, quantization, and pruning are applied to improve efficiency. This step is essential for balancing the model's accuracy and resource usage, making it suitable for practical deployment.
🏋️ How to Train Custom Large Language Model
Building custom LLM from scratch involves several practical steps and technologies, which our developer Andrian will also discuss:
Firstly, you'll need a substantial dataset, which can be gathered from diverse sources like web scraping, open datasets, or proprietary data, and then preprocessed to remove noise and irrelevant information.
Libraries such as BeautifulSoup for web scraping and pandas for data manipulation are highly useful. Once the data is ready, the model architecture needs to be defined, with Transformer-based models like GPT-3 or BERT being popular choices.
Training a custom large language model requires gathering extensive, high-quality datasets and leveraging advanced machine learning techniques.

Frameworks such as TensorFlow and PyTorch provide robust tools for building and training these models, with Hugging Face's Transformers library offering pre-built architectures and utilities to simplify the process. Training a large language model demands significant computational power, often requiring GPUs or TPUs, which can be provisioned through cloud services like AWS, Google Cloud, or Azure.
Monitoring tools such as TensorBoard can help track training progress and performance metrics like loss and accuracy, enabling adjustments to hyperparameters for optimal results.
Retrieval-Augmented Generation (RAG) is an alternative approach that combines the strengths of retrieval-based methods with generative AI models. Instead of training a model from scratch, RAG leverages a retriever to fetch relevant documents from a pre-existing corpus and a generator to produce coherent and contextually accurate responses. This approach is particularly advantageous when dealing with specific, domain-focused tasks where the corpus contains highly specialized information.
Using RAG can significantly reduce the computational and data requirements compared to training a new model from scratch. Moreover, RAG is effective for scenarios where up-to-date information is critical, as the retriever can dynamically pull in the latest data, ensuring the generated output is both accurate and relevant. Integrating RAG can be efficiently done using frameworks like Hugging Face's Transformers, which supports RAG models and offers pre-trained components that can be fine-tuned for specific applications.

🏔️ Challenges in Creating an LLM
Assembling one individually from the ground up is a herculean task, especially for small to medium businesses, large entities, or startups that may already have some experience with LLMs but now want to gain a fuller appreciation of what is involved. Below are the primary challenges that you may face during this complex process:
Data Collection and Quality
Effective training of a satisfactorily performing LLM entails the use of a massive amount of data that possesses high variety. Collection of such data can sometimes be a very difficult endeavor. The data needs to be diverse in the topics discussed, languages used, and environments in which the information was made available online.
(video by Cadabra Studio)
Controlling the content of the data collected is essential so that data errors, biases, and irrelevant content are kept to a minimum. Low-quality data impacts the quality of further analysis and the models built, which affects the performance of the LLM.
Computational Resources
Training LLMs, especially those with billions of parameters, requires large amounts of computation. This includes GPUs or TPUs, which are pricey and heavily energy-intensive.
It can sometimes be technically complex and laborious to coordinate and expand computational resources to accommodate numerous training procedures.
Model Complexity
It is crucial to correctly select the architecture of LLM (for example, autoregressive, autoencoding, or combined ones) depending on the concrete problem that is going to be solved. Each architecture has its advantages and disadvantages, and a wrong decision can lead to poor results.
Tweaking the hyperparameters (for instance, learning rate, size of the batch, number of layers, etc.) is a very time-consuming process and has a decided influence on the result. It requires experts, and this usually entails a considerable amount of trial and error.
Data Privacy and Security
There are privacy issues during the training phase when processing sensitive data. The importance of enforcing measures such as federated learning and differential privacy cannot be overemphasized. However, they increase the difficulty level.
It is obligatory to be compliant with data protection regulations (for example, GDPR, CCPA). This requires proper management of data and documentation so that an organization will not fall prey to legal actions.
Data privacy and security in creating an LLM are critical, as they involve ensuring compliance with regulations like GDPR and preventing sensitive data leaks during the training phase.

Cost Management
The monetary investment to create a LLM model for data acquisition, computing resources, and talent is a huge capital investment that one has to make. These costs may, however, be expensive for SMEs that may not be in a position to meet the costs as big organizations do.
There are additional costs that accompany the maintenance and improvement of the LLM as well. Since developing the LLM was not a one-time process, sustaining and enhancing it also has recurring expenses. Efficiency of resource management is needed to prevent these costs from escalating.
Expertise and Talent
Therefore, developing, and especially tuning, an NLP model such as an LLM entails knowledge in machine learning, data science, and more specifically in NLP. Securing such talent is quite a process, especially when the market is competitive, and human resources must endure a learning curve before the candidate is actually hired.
The field in which LLMs are concentrated is dynamic and developing very fast at the moment. To remain informed of current research as well as the available technological solutions, one has to learn constantly. It is about constant development.
Ethical Considerations
It is important to eliminate bias in the model and reflect on the model’s potential for presenting a fair outcome. This includes paying particular attention to the data that is used during training and measures put in place to counteract this.
Staying ahead of the curve when it comes to how LLMs are employed and created is a continuous challenge due to the significant danger of having LLMs that spread information unethically.
Perhaps, it is a great challenge to create your own LLM due to many technical, financial, and ethical barriers. That being said, if these components are thought through and executed to the best of one's abilities, there is a way to design the model to your needs and offer rather tangible competitive advantages.
