The Best Large Language Models


We live in a world where Artificial Intelligence (AI) is taking over many aspects of our lives. From healthcare to retail, AI is being used to make decisions, automate processes, and drive efficiency. One of the core components of AI is the use of large language models, which allow machines to understand and process human language.

In this blog post, we’ll take a look at the current best, high-performance large language models, and how they can be used to improve your business. We’ll also explore how these models can help with market research, customer experience management, product research, SEO, business analysis, data science, and academic research.

What are Language Models?

A language model is a set of mathematical tools and algorithms used to analyze, process, and represent natural language (or human language). This includes English, Spanish, French, Chinese, and any other language spoken by humans. The goal of language models is to enable machines to understand, process, and generate texts in a human-like manner.

Language models can take various forms. Some models are shallow, meaning they are limited in their ability to understand and process language. Other models are deep, meaning they are able to understand and process complex language.

The most advanced language models are “large” language models. These models are “large” because they are trained on massive amounts of data (usually billions of words). They are also “high-performance” because they are able to accurately and quickly process and understand language.

The Current Best, High-Performance Large Language Models

There are several large language models currently being used in the world of AI. The most popular models are Google’s BERT, OpenAI’s GPT-3, and Microsoft’s Transformer.

Google’s BERT (Bidirectional Encoder Representations from Transformers)

Google's BERT is a deep learning algorithm that can be used to understand and process natural language. It was released in 2018, and it has become one of the most widely used language models in the world.

OpenAI’s GPT-3 (Generative Pre-trained Transformer 3)

GPT-3 is a large-scale language model that was released in 2020. It is able to generate natural language from input data, and it is being used in many AI applications. There are continual advancements here with the recent OpenAI release of ChatGPT.

OpenAI’s GPT-4 (Generative Pre-trained Transformer 4)

The landscape of artificial intelligence has witnessed a remarkable leap with the advent of Generative Pre-trained Transformer 4 (GPT-4), a cutting-edge language model developed by OpenAI. As the fourth iteration in the GPT series, GPT-4 was unveiled to the public on March 14, 2023, and has since garnered significant attention for its advanced capabilities. Access to GPT-4 is facilitated through ChatGPT Plus, a subscription-based service, while commercial users can join a waitlist to access the model's API.

Pre-training and Fine-tuning:

GPT-4's architecture is based on the transformer model, and its training process involves two key stages: pre-training and fine-tuning. During pre-training, GPT-4 learns to predict subsequent tokens in a sequence using a diverse dataset that includes publicly available content as well as data sourced from third-party providers. The fine-tuning phase employs reinforcement learning, incorporating feedback from both humans and AI to optimize the model's alignment with human values and adherence to ethical guidelines.

Enhancements Over Predecessors:

GPT-4's introduction to the ChatGPT platform has been met with positive feedback, as users have noted its enhanced performance compared to the earlier GPT-3.5 version. Despite these advancements, GPT-4 is not without its limitations, and some challenges from previous versions persist. A notable distinction of GPT-4 is its multimodal nature, which allows the model to process both textual and visual inputs. This capability enables GPT-4 to interpret images, summarize text within screenshots, and respond to queries that include diagrams.

Technical Specifications:

OpenAI has remained discreet about certain technical details of GPT-4, including the model's size. However, it is known that GPT-4 is available in two versions, each with different context window lengths: 8,192 and 32,768 tokens. This expansion in context window size represents a significant upgrade from GPT-3 and GPT-3.5, which were limited to 2,049 and 4,096 tokens, respectively.

Multimodal Capabilities:

GPT-4's ability to process both text and images sets it apart from its predecessors. This multimodal functionality allows GPT-4 to perform tasks such as identifying humor in unconventional images, summarizing text within visual content, and answering questions that incorporate diagrams.

System Message Feature:

OpenAI has introduced an innovative feature known as the "system message" to enhance user control over GPT-4's behavior. Through this feature, users can provide natural language directives to specify the model's tone and task. For instance, users can instruct GPT-4 to adopt the persona of a "Shakespearean pirate" or to format responses in JSON. GPT-4 is designed to adhere to the system message, even if subsequent user interactions request a deviation from the initial directive.

Microsoft’s Transformer

Microsft's Transformer is a deep neural network which is used to process natural language. It was released in 2017, and it is used in many of Microsoft’s products and services.


Cohere is building large language models that are showing promise. Like OpenAI, you can interact through APIs and a playground interface and select different models, sizes, and functions within those models.

Stable Diffusion

Stability Ai has built a large language model that is being used primarily for text-to-image and has taken the world by storm. This model continues to improve with constant updates, releases, improvements and configurations by other developers who love their open-source capacities. 

How Can Large Language Models Help Your Business?

Large language models can help businesses in a variety of ways. Here are just a few examples:
