The Future of Language Generation: The 12 Best Large Language Models

The landscape of Large Language Models (LLMs) is rapidly evolving, with the latest models pushing the boundaries of what's possible in artificial intelligence. As these models continue to shape the way we interact with technology, the possibilities for generative AI applications are limitless. Thanks to fine-tuned models, developers, businesses, and entrepreneurs alike are presented with a powerful toolset to create innovative solutions, engaging user experiences, and address a wide range of tasks. In this article, we'll explore the best large language models.

‍

What are Large Language Models?

Large language models, such as OpenAI's GPT-3.5, are sophisticated artificial intelligence systems designed to understand and generate human-like text based on input provided to them. These models are characterized by their vast scale, with billions or even trillions of parameters that enable them to capture intricate patterns and nuances in language. 

‍

The mechanisms within these models involve neural networks, specifically transformer architectures, allowing them to process and generate contextually relevant and coherent text. Pre-trained on extensive datasets, these models have learned to predict the next word in a sentence or complete text passages, acquiring a broad understanding of language structure, grammar, and context. The applications of large language models are diverse, ranging from natural language processing tasks to creative content. 

‍

They can be employed to draft emails, generate code, answer questions, translate languages, and much more. Search engines also benefit from large language models by utilizing them to improve the relevance and context of search results. The pre-trained nature of these models allows for adaptation to specific domains or tasks with fine-tuning, making them versatile tools for various applications in the realm of artificial intelligence and natural language understanding.

What is the Difference Between Open Source and Closed Source LLM?

The terms "open source" and "closed source" refer to the accessibility of the underlying code of a language model, such as a Large Language Model (LLM). Here's a breakdown of the key differences:

‍

Open Source Language Models

• Transparency: An open-source large language model has its source code accessible to the public. Anyone can view, modify, and distribute the code.
• Community Collaboration: The open-source nature encourages collaboration from the broader developer and research community. This often results in diverse contributions and improvements.
• Customization: Users have the flexibility to modify the code to suit their specific needs or to address particular challenges. This adaptability can lead to a wide range of applications and use cases.
• Examples: BERT, GPT (Generative Pre-trained Transformer) models, and others have open-source implementations.

Closed Source (Proprietary) Language Models

• Restricted Access: The source code for closed source language models is not publicly available. It is owned and maintained by a specific entity or organization.
• Limited Modification: Users typically do not have the ability to modify or customize the underlying code. The model is used as a service or software without direct access to the internal workings.
• Controlled Distribution: The entity that owns the closed source model controls distribution and updates. Users may have to rely on official releases and updates provided by the owner.
• Examples: Some commercial language models or those developed by private companies might fall into the closed-source category.

Considerations

• Licensing: Open source models often come with specific licenses that dictate how the code can be used, modified, and distributed. Closed source models may have more restrictive usage terms.
• Community Support: Open source models benefit from community-driven support and improvements. Closed source models rely on the entity that owns them for support and updates.

‍

In the context of LLMs, models like GPT-3 from OpenAI have been commercially deployed, allowing users to access the model through an API, while the underlying model architecture remains proprietary. Understanding whether a language model is open source or closed source is crucial for developers and researchers, as it determines the level of accessibility, collaboration, and customization available for the model.
