In this article, we are getting an overview of LLM and some of the best Large Language Models that exist today.
In 2023, Artificial Intelligence (AI) is a hot topic, captivating millions of people worldwide. AI’s remarkable language capabilities, driven by advancements in Natural Language Processing (NLP) and Large Language Models (LLMs) like ChatGPT from OpenAI, have contributed to its popularity.
LLM, like ChatGPT, LaMDA, PaLM, etc., are advanced computer programs trained on vast textual data. They excel in tasks like text generation, speech-to-text, and sentiment analysis, making them valuable tools in NLP. The model’s parameters enhance its ability to predict word sequences, improving accuracy and handling complex relationships.
Introducing large language models in NLP
Natural Language Processing (NLP) has seen a surge in popularity due to computers’ capacity to handle vast amounts of natural text data. NLP has been applied in technologies like speech recognition and chatbots. Combining NLP with advanced Machine Learning techniques led to the emergence of powerful Large Language Models (LLMs).
Trained on massive datasets of text, reaching millions or billions of data points, these models demand significant computing power. To put it simply, if regular language models are like gardens, Large Language Models are like dense forests.
How do large language models do their work?
LLMs, powered by the transformative architecture of Transformers, work wonders with textual data. These Neural Networks are adept at tasks like language translation, text generation, and answering questions. Transformers can efficiently scale and handle vast text corpora, even in the billions or trillions.
Unlike sequential RNNs, they can be trained in parallel, utilizing multiple resources simultaneously for faster learning. A standout feature of Transformers is their self-attention mechanism, enabling them to understand language meaningfully, grasping grammar, semantics, and context from extensive text data.
The invention of Transformers revolutionized AI and NLP, leading to the creation of numerous LLMs utilized in various applications like chat support, voice assistants, chatbots, and more. In this article, we’ll explore five of the most advanced LLMs in the world as of 2023.
