What are Large Language Models?

Large language models or LLMs are a cutting-edge form of artificial intelligence that have gained significant attention in recent years. These models are designed to understand and generate human language, making them incredibly powerful tools for a wide range of applications.

At their core, large language models like GPT 4 are trained on vast amounts of text data, such as books, articles, and websites. This training allows the model to learn the rules and patterns of language, enabling it to generate coherent and contextually appropriate responses.

What are parameters in AI?

Before we take a look at some of the best LLMs, there is a term that you may come across frequently called ”parameters”. So, what are they? 

Parameters simply refer to variables that are modified during the training phase in order to determine how input data is converted into the desired output. These individual parameters correspond to values that are obtained and adjusted by an AI algorithm throughout the training process.

This enables it to make informed decisions and predictions. The values of these parameters have a significant impact on the performance of a model and influence factors such as accuracy, speed, and generalization capabilities.

What are the 10 best Large Language Models?

LLMs have revolutionized the field of natural language processing (NLP) and artificial intelligence (AI). With how competitive this field is, there have already been quite a lot of LLMs. But there are a handful that stand out.


This is the forefront of AI large language models in 2023. Developed by OpenAI and unveiled in March, this remarkable model showcases a range of astonishing capabilities. It has a profound understanding of complex reasoning, advanced coding abilities, exceptional performance in various academic evaluations, and numerous other competencies that mirror human-level proficiency. 

GPT-4 also incorporates multimodal capability. This enables it to process both text and image inputs. While ChatGPT has yet to inherit this feature, fortunate users have experienced it through Bing Chat, which harnesses the power of the GPT-4 model.


GPT-3.5 is a versatile LLM. it excels in speed, providing complete responses within seconds. Whether it's crafting essays using ChatGPT or developing business plans, GPT-3.5 performs admirably. 

Additionally, OpenAI has expanded the context length to a generous 16K for the GPT-3.5-turbo model, further enhancing its appeal. This model can also be used freely without any hourly or daily limitations.

PaLM 2 (Bison-001) 

This large language model  by Google has emerged as a standout among the leading large language models of 2023. What sets this model apart is its strong focus on vital areas such as commonsense reasoning, formal logic, mathematics, and advanced coding across over 20 languages. 

The most comprehensive version of PaLM 2 has been trained with an astounding 540 billion parameters and boasts an impressive maximum context length of 4096 tokens. PaLM 2 comprises four different models within its framework: Gecko, Otter, Bison, and Unicorn. 

Currently only Bison is accessible to users. In terms of performance evaluation based on the MT-Bench test, Bison achieved a score of 6.40 and falls slightly behind GPT-4's remarkable score of 8.99 points.

Claude v1

In 2023, Anthropic, a company founded by former employees of OpenAI and backed by Google, launched Claude v1, an impressive competitor in the realm of large language models. Anthropic's primary goal is to develop AI assistants endowed with qualities such as helpfulness, honesty, and harmlessness. 

The remarkable performance of both the Claude v1 and Claude Instant models has been evident in various benchmark tests, surpassing PaLM 2 in both the MMLU and MT-Bench evaluations. It achieves a score of 7.90 in the MT-Bench test, while GPT-4 attains 8.99. In the MMLU benchmark, Claude v1 secured 75.6 points, slightly trailing behind GPT-4's score of 86.4.

These scores provide insights into model performance and help drive advancements in natural language processing.

WizardLM is an open-source large language model that has been developed by AI researchers using the Evol-instruct technique. Its primary objective is to effectively comprehend complex instructions. 

One notable feature of WizardLM is its capability to rephrase initial instructions into more complex ones. The resulting instruction data is then utilized to fine-tune the LLaMA model, thereby enhancing its performance.

Gopher – Deepmind

Deepmind's creation, the Gopher, is an awe-inspiring model encompassing 280 billion parameters. It showcases remarkable proficiency in understanding and generating language, while demonstrating exceptional aptitude across diverse domains such as mathematics, science, technology, humanities, and medicine.

Moreover, it also possesses the unique capability to simplify complex subjects during interactive conversations. With its expertise in reading, fact checking and identification of harmful language, Gopher undoubtedly proves to be an invaluable asset.
