Which is the best LLM on the market?

Nov 20, 2023

Misc

AI technologies are evolving rapidly but, let's be honest, there are not many companies developing LLM models in the market, except for three different strong competitors: OpenAI, Meta, and Google.

With its recent investments in AI technologies and wearable technology, such as Meta Smart Glasses, Meta has made an ambitious entry into the sector with the LLama-2 model. The successful company, which has managed to improve its LLM a lot in the past few months, has managed to write its name among the most powerful artificial intelligence model developers.

Welcome to our LLama-2 vs GPT-3.5 and PaLM 2 writing, where we will take a look at Meta's current position in the AI race.

LLama-2 vs GPT-3.5

Let's start with the LLama-2 vs GPT-3.5 comparison. As mentioned before, Llama 2 and GPT-3.5 are both large language models (LLMs) developed by Google AI and Meta.

They are both capable of generating text, translating languages, writing different kinds of creative content, and answering your questions in an informative way. However, there are some key differences between the two models.

LLama-2 vs GPT-3.5: Parameter size

One of the main differences between Llama 2 and GPT-3.5 is their parameter size. Parameter size is a measure of the complexity of an LLM, and it is generally considered to be a good indicator of its performance.

Llama 2 has a parameter size of 70 billion, while GPT-3.5 has a parameter size of 175 billion. This means that GPT-3.5 is theoretically capable of more complex tasks than Llama 2.

LLama-2 vs GPT-3.5: Accuracy

However, parameter size is not the only factor that determines the performance of an LLM. Accuracy is also important, and it is a measure of how often an LLM generates correct output.

In terms of accuracy, Llama 2 and GPT-3.5 are very similar. Both models are capable of generating text that is factually accurate and grammatically correct.

LLama-2 vs GPT-3.5: Efficiency

Another important factor to consider is efficiency. Efficiency is a measure of how much computational power an LLM requires to generate output. Llama 2 is much more efficient than GPT-3.5.

This is because Llama 2 is trained on a dataset that is specifically designed to be efficient. This means that Llama 2 can generate output much faster than GPT-3.5, and it also requires less computational power.

LLama-2 vs GPT-3.5: Cost

Finally, it is also important to consider the cost of using each model. Llama 2 is much less expensive to use than GPT-3.5.

This is because Llama 2 is open-source, while GPT-3.5 is a proprietary model. This means that anyone can use Llama 2 for free, while GPT-3.5 requires a paid subscription unless you are using it through OpenAI's ChatGPT.

Interpretation: Llama 2 is smaller, more efficient, and less expensive than GPT-3.5 but has a smaller parameter size.

LLama-2 vs PaLM 2

Let's continue by comparing Meta and Google's LLMs.

LLama-2 vs PaLM 2: Parameter size

PaLM 2 has a much larger parameter size than Llama 2. This means that PaLM 2 has a more complex architecture and is able to process more information. This can give PaLM 2 an advantage in tasks that require a deep understanding of language, such as natural language understanding and natural language generation.

However, it also means that PaLM 2 is more computationally expensive to run than Llama 2.

LLama-2 vs PaLM 2: Accuracy

Both Llama 2 and PaLM 2 are highly accurate models. They are able to generate text that is factually accurate and grammatically correct. However, PaLM 2 is generally considered to be more accurate than Llama 2.

This is because PaLM 2 has a larger parameter size and is able to process more information.

LLama-2 vs PaLM 2: Efficiency

Llama 2 is a very efficient model. It is able to generate text quickly and requires less computational power than PaLM 2.

This makes Llama 2 a good choice for applications that require a lot of processing power, such as real-time chatbots and virtual assistants.

LLama-2 vs PaLM 2: Cost

Llama 2 is an open-source model, which means that it is available for free. PaLM 2 is a proprietary model, which means that it requires a paid subscription to use unless you are using it through Google Bard.

This makes Llama 2 a more affordable option for businesses and organizations.

Interpretation: PaLM 2 is theoretically capable of more complex tasks than Llama 2, and it is also more efficient and more expensive to use.

A final clash

What do the differences between the three LLMs mean and which is better? Let's ask all three LLMs the question that philosophers have been trying to answer for centuries: What is the meaning of life?

And of course, we will provide a table afterward where we compare LLama-2 vs GPT-3.5 vs PaLM-2.

Our prompt: What is the meaning of life? Explain as short as you can.

LLama-2's answer

The meaning of life is to find purpose, happiness, and fulfillment through personal growth, relationships, and contributions to society.

ChatGPT's (GPT-3.5) answer

The meaning of life is subjective and varies for each individual. It often involves finding purpose, happiness, and personal fulfillment.

Bard's (PaLM-2) answer

The meaning of life is a complex and multifaceted question that has been pondered by philosophers and theologians for centuries. There is no single answer that will satisfy everyone, but some possible answers include:

To find happiness and fulfillment

To make a difference in the world

To learn and grow as a person

To connect with others and build relationships

To experience the beauty of the world

To leave a legacy behind

Ultimately, the meaning of life is up to each individual to decide. What matters most is that you find something that gives your life meaning and makes it worth living.

Interpretation: While Google Bard, the PaLM-2 model, gave a much more comprehensive answer than other LLMs, it ignored the "Explain as short as you can" part of our prompt. LLama-2's answer and GPT-3.5's answer, on the other hand, are quite similar.

Now that we have put all three LLMs to the test with this complex question, let us also provide a table to summarize our LLama-2 vs GPT-3.5 vs PaLM-2 comparison.

Feature	Meta Llama 2	OpenAI GPT-3.5	Google PaLM-2
Parameter size	70 billion	175 billion	540 billion
Accuracy	High	High	Very high
Efficiency	Highest	Moderate	Lowest
Cost	Free	High	Very high
Source	Open-source	Proprietary	Proprietary

Now you: Which LLM is the winner of the LLama-2 vs GPT-3.5 vs PaLM-2 comparison?
