But as these terms became more famous, so did the confusion. Confusion about whether both of these are the same, similar, or different. “How does Generative AI compare to LLM?” is a question that many still cannot answer.
We consulted ChatGPT to clear the air for us, before we dive deep, and here’s the response from the model itself.
“Generative AI focuses on creating new content, such as text, images, or music, based on input prompts. It uses algorithms trained to generate original outputs by understanding patterns in existing data.
LLMs (Large Language Models) are a subset of AI models specifically designed for natural language understanding and generation.“
Did it make sense? If not, we’ll dive deep into definitions of both technologies and discover how they differ based on their unique capabilities, limitations, and real-world use cases across industries. In this post, we aim to cover differences, the common points, and what it really means for the future of AI.
What is Generative AI, or Gen AI?
Generative AI, also known as Gen AI, is a sub-technology of artificial intelligence that generates new content. This includes unique and creative textual content, images, videos, audio, and more. It differs from traditional AI models that are focused on defined rule-structure, and works on the model of if-else.
Once fed with data, Gen AI uses probabilistic capabilities to create new and unique outputs for the user, depending on the input.
What are LLMs or Large Language Models?
LLMs, also called Large Language Models, are a subset of Generative AI that are specifically built for creating new content. LLMs (Large Language Models) are primarily designed for text-based tasks such as understanding, generating, and transforming natural language.
While they excel in handling language-related challenges, they are not inherently designed for multimedia content creation like images, audio, or video.
For multimedia content, multi-modal AI models or other specialized generative AI systems are more suitable, as they are explicitly trained to process and generate non-textual data.
However, LLMs can complement these systems by generating descriptive text, prompts, or delivering context that multi-modal models use to produce multimedia outputs.
