LLaMA 2 vs GPT-4: What are the Differences?

3 min

Discover the key distinctions between LLaMA 2 and GPT-4, the leading giants of natural language processing. Uncover their strengths, weaknesses and how they shape the future of language technology.

When it comes to writing content, two factors are crucial, “perplexity” and “burstiness.” Perplexity measures the complexity of the text. Separately, burstiness compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or more complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In the world of natural language processing, two prominent players, LLaMA 2 and GPT-4, have captured the attention of researchers and enthusiasts alike. These large language models (LLMs) showcase their capabilities in diverse ways, each with unique features and functionalities.

While GPT-4 is out for a while by OpenAI, in a surprising collaboration with Microsoft, Meta has launched LLaMA 2, an improved version of its expansive language model, LLaMa.

Let’s delve into the key distinctions between the two models to understand what sets them apart.

LLaMA 2: Simple and usuable

LLaMA 2, an upgraded version of its predecessor LLaMa, has astounded the tech world with its simplicity and efficiency. Although it supports a narrower range of languages, encompassing 20 languages, its performance is nothing short of impressive and can compete with heavyweight models like GPT-4, Claude, or Bard. Surprisingly, despite having fewer parameters than GPT-3 models, LLaMA 2 can run effectively on a single GPU, making it a more accessible choice for various applications.

What truly sets LLaMA 2 apart is its exclusive training on openly accessible datasets, making it more available to researchers and developers. Even more remarkably, it achieves competitive results despite being trained on a relatively modest dataset of only 1,000 precise prompts.


In March 2023, OpenAI proudly introduced its latest creation, GPT-4, which took the world of language models by storm. The GPT-4 excels in a multitude of tasks, including professional medical and law exams, showcasing its versatility and proficiency.

One of the defining features of GPT-4 is its ability to expand on the maximum input length compared to its predecessors. This enhancement allows it to process even more extensive and complex language data, opening new avenues for natural language understanding and generation.

Furthermore, GPT-4 boasts extensive language support, accommodating 26 languages. This diverse linguistic capability broadens its global reach and applicability, making it a preferred choice for multilingual projects and applications.

Differences: LLaMA 2 vs GPT-4

As we compare LLaMA 2 and GPT-4, it becomes evident that both models have their unique strengths and weaknesses. LLaMA 2 stands out with its simplicity and efficiency, performing remarkably well despite its smaller dataset and limited language support. Its accessibility and competitive results make it a compelling option for certain applications.

On the other hand, GPT-4’s impressive performance across various tasks and vast language support make it a formidable choice for more complex and diverse projects. However, the lack of detailed information on its model architecture and training datasets leaves some questions unanswered.

Here are some of the benchmark scores of both models (alongside other popular ones):
