For many, one of the most confusing aspects of generative AI and its expansion into the mainstream is the terminology.

After all, given how new the technology is to most of us, terms like ‘natural language processing,’ ‘machine learning,’ and‘ search generative intelligence,’ may not be very familiar.

But perhaps the most common phrase AI enthusiasts will hear is large language models (LLMs)

Platforms often reference using them as part of their service, but very few dive into detail about what they actually are.

In this article, we will break down large language models, so you can keep learning more about artificial intelligence.

Short on Time? Here Are the Key Takeaways

  • Large language models gather and process vast amounts of data and then call upon it to answer consumer queries.
  • ChatGPT is one of the most popular and frequently used large language models.
  • Originality.ai’s AI Content Detector is a best-in-class AI detector that helps to maintain transparency in web publishing.

What Are Large Language Models (LLMs)?

Let’s dive straight in and answer your top question. What are large language models (LLMs)?

According to Amazon Web Services, large language models also referred to as LLMs for short, are essentially extensive deep-learning models.

  • These models have been pre-trained on considerable amounts of data. 
  • They use an encoder and decoder to extract meanings from a string of text and establish the relationships between words and phrases.

Now, that might sound like quite a complex answer, so here’s an example.

Let’s say, someone is searching for a new bass. This could refer to either bass the instrument or bass the fish.

Both words are spelt exactly the same, which is why it’s crucial that LLMs have the necessary training and enough data to ensure the tools can ‘read between the lines’ if you will and understand the context of what you are asking.

So, using that example, if a user asks ChatGPT, “give me the top 10 places to find a bass,” the tool will make a decision on whether or not they are likely to be looking for fishing spots or music stores. In the same way, an LLM-powered PDF annotation tool could analyze text and highlight relevant mentions of "bass" based on the context of the document.

Here’s the result:

Of course, this is a rather extreme example, and others are much more nuanced, but it gives you an idea of the process that takes place.

The large language model reads the request, scours its vast dataset, and makes decisions on which question the user is asking.

Is ChatGPT a large language model?

This brings us to another common question about LLMs. Is ChatGPT a large language model?

The answer is yes; ChatGPT is one of the most popular examples of a large language model (read more about foundational LLM models). 

As demonstrated in the example above, ChatGPT uses its vast data and training to answer consumer queries to the best of its ability. 

ChatGPT and knowledge cutoffs

It’s also important to note that ChatGPT is subject to a knowledge cutoff date. This is the reason why ChatGPT isn’t always as good at answering questions on the most up-to-date topics, as it has yet to consume the most recent data required to provide a good answer.

When ChatGPT was first launched in the mainstream, the gap between knowledge and current events was dated to September 2021 as noted by the Poynter Institute.  

As of the publication of this article, the knowledge cutoff date is now October 2023 for GPT-4o, confirmed by OpenAI.

AI Content Detection for Text Generated by LLMs

Another common question is: How can you maintain transparency with text generated by LLMs?

Although humans might have confidence that they can identify AI, several studies have found that humans struggle to identify AI text. This is where AI detection comes in. 

Originality.ai offers a best-in-class and industry-leading AI Detector. Using an AI detector as part of the editorial process helps to establish and maintain transparency around the content published, whether you’re a content marketer, web publisher, or editor. 

When you run an AI detection scan with text generated by a popular LLM such as GPT-4o, Gemini Pro, or Llama 3.1 you’ll receive an AI detection score indicating the confidence that the text is Likely AI or Likely Original.

Frequently Asked Questions About LLMs

Are large language models accurate?

Large language model accuracy depends on the task in question, the quality of the prompt, and the depth of its training data. 

One of the top issues with generative AI is that it can produce AI hallucinations. AI hallucinations occur when a generative AI model generates an inaccurate statement that it presents as a fact. So, it’s important to fact-check and review content carefully.

Are large language models biased?

Large language models are trained on extensive datasets and if the data contains bias it could replicate this in its generations. This has made AI governance and responsible AI an increasingly important focus in AI development.

What are the benefits of using LLMs?

There are pros and cons to generative AI. That said, when used effectively they can be incredibly useful tools for making certain tasks more efficient. For instance, AI can be beneficial from a content marketing perspective for ideating topics or conducting initial research

Just keep in mind, that the best practice when incorporating LLMs into your workflow is to maintain transparency. For instance, when writing content, review AI guidelines and policies right from the beginning of a writing contract before submitting work, so that everyone is on the same page.

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?
