LLMs are typically built using a transformer architecture. Transformers are a type of neural network that are well-suited for natural language processing tasks. They are able to learn long-range dependencies between words, which is essential for understanding the nuances of human language.

They are typically trained on clusters of computers or even on cloud computing platforms. The training process can take weeks or even months, depending on the size of the dataset and the complexity of the model.

20 essential terms for crafting LLM-powered applications

 

1. Large language model (LLM)

Large language models (LLMs) are AI models that can generate text, translate languages, write different kinds of creative content, and answer your questions in an informative way. The building blocks of an LLM are embeddings, transformers, attention, and loss functions. Embeddings are vectors that represent the meaning of words or phrases. Transformers are a type of neural network that are well-suited for NLP tasks.

13. Midjourney

Midjourney is a LLM developed by Midjourney. It is a text-to-image AI platform that uses a large language model (LLM) to generate images from natural language descriptions. The user provides a prompt to Midjourney, and the platform generates an image that matches the prompt. Midjourney is still under development, but it has the potential to be a powerful tool for creative expression and problem-solving.

14. Prompt Engineering

Prompt engineering is the process of crafting prompts that are used to generate text with LLMs. The prompt is a piece of text that provides the LLM with information about what kind of text to generate.

Prompt engineering is important because it can help to improve the performance of LLMs. By providing the LLM with a well-crafted prompt, you can help the model to generate more accurate and creative text. Prompt engineering can also be used to control the output of the LLM. For example, you can use prompt engineering to generate text that is similar to a particular style of writing, or to generate text that is relevant to a particular topic.

When crafting prompts for LLMs, it is important to be specific, use keywords, provide examples, and be patient. Being specific helps the LLM to generate the desired output, but being too specific can limit creativity.

Using keywords helps the LLM focus on the right topic, and providing examples helps the LLM learn what you are looking for. It may take some trial and error to find the right prompt, so don’t give up if you don’t get the desired output the first time.

15. Embeddings

Embeddings are a type of vector representation of words or phrases. They are used to represent the meaning of words in a way that can be understood by computers. LLMs use embeddings to learn the relationships between words. Embeddings are important because they can help LLMs to better understand the meaning of words and phrases, which can lead to more accurate and creative text generation. Embeddings can also be used to improve the performance of other NLP tasks, such as natural language understanding and machine translation.

16. Fine-tuning

Fine-tuning is the process of adjusting the parameters of a large language model (LLM) to improve its performance on a specific task. Fine-tuning is typically done by feeding the LLM a dataset of text that is relevant to the task.

For example, if you want to fine-tune an LLM to generate text about cats, you would feed the LLM a dataset of text that contains information about cats. The LLM will then learn to generate text that is more relevant to the task of generating text about cats.

Fine-tuning can be a very effective way to improve the performance of an LLM on a specific task. However, it can also be a time-consuming and computationally expensive process.

17. Vector databases

Vector databases are a type of database that is optimized for storing and querying vector data. Vector data is data that is represented as a vector of numbers. For example, an embedding is a vector that represents the meaning of a word or phrase.

Vector databases are often used to store embeddings because they can efficiently store and retrieve large amounts of vector data. This makes them well-suited for tasks such as natural language processing (NLP), where embeddings are often used to represent words and phrases.

Vector databases can be used to improve the performance of fine-tuning by providing a way to store and retrieve large datasets of text that are relevant to the task. This can help to speed up the fine-tuning process and improve the accuracy of the results.

18. Natural Language Processing (NLP)

Natural Language Processing (NLP) is a field of computer science that deals with the interaction between computers and human (natural) languages. NLP tasks include text analysis, machine translation, and question answering. LLMs are a powerful tool for NLP. NLP is a complex field that covers a wide range of tasks. Some of the most common NLP tasks include:

  • Text analysis: This involves extracting information from text, such as the sentiment of a piece of text or the entities that are mentioned in the text.
    • For example, an NLP model could be used to determine whether a piece of text is positive or negative, or to identify the people, places, and things that are mentioned in the text.
  • Machine translation: This involves translating text from one language to another.
    • For example, an NLP model could be used to translate a news article from English to Spanish.
  • Question answering: This involves answering questions about text.
    • For example, an NLP model could be used to answer questions about the plot of a movie or the meaning of a word.
  • Speech recognition: This involves converting speech into text.
    • For example, an NLP model could be used to transcribe a voicemail message.
  • Text generation: This involves generating text, such as news articles or poems.
    • For example, an NLP model could be used to generate a creative poem or a news article about a current event.

19. Tokenization

Tokenization is the process of breaking down a piece of text into smaller units, such as words or subwords. Tokenization is a necessary step before LLMs can be used to process text. When text is tokenized, each word or subword is assigned a unique identifier. This allows the LLM to track the relationships between words and phrases.

There are many different ways to tokenize text. The most common way is to use word boundaries. This means that each word is a token. However, some LLMs can also handle subwords, which are smaller units of text that can be combined to form words.

For example, the word “cat” could be tokenized as two subwords: “c” and “at”. This would allow the LLM to better understand the relationships between words, such as the fact that “cat” is related to “dog” and “mouse”.

20. Transformer models

Transformer models are a type of neural network that are well-suited for NLP tasks. They are able to learn long-range dependencies between words, which is essential for understanding the nuances of human language. Transformer models work by first creating a representation of each word in the text. This representation is then used to calculate the relationship between each word and the other words in the text.

The Transformer model is a powerful tool for NLP because it can learn the complex relationships between words and phrases. This allows it to perform NLP tasks with a high degree of accuracy. For example, a Transformer model could be used to translate a sentence from English to Spanish while preserving the meaning of the sentence.
