Do you remember when ChatGPT by OpenAI debuted in November 2022? Within days, it stunned the world with its unprecedented capabilities, marking the dawn of the generative AI revolution. Everyone wondered, what comes next?
At the time, ChatGPT and other Generative AI tools powered by Large Language Models (LLMs) could accept text inputs and generate corresponding text outputs. These tools were simply known as unimodal AI tools.
But that was just the beginning—a mere glimpse of what LLMs could achieve. Since then, industry advancements have been so profound that the potential long-term implications of ChatGPT and generative AI seem limitless.
Today, if someone were to ask what lies ahead, the answer would likely involve multimodal learning. This trend is among the most promising in the ongoing AI revolution. Multimodal generative AI models can handle diverse types of inputs and produce various types of outputs.
In this blog post, we will explore multimodal AI: its definition, multimodal LLMs, underlying technologies, examples, and real-world applications. Are you ready to delve into multimodal AI? Let's get started!
What exactly is Multi Modal AI?
Initially, artificial intelligence (AI) algorithms capable of generating text, like ChatGPT, operated in a unimodal fashion. This means they were restricted to processing only one type of input and consistently produced outputs in the same format. Typically, these models were optimized to process textual prompts and generate corresponding text responses.
This emphasis on text is practical because text data is abundant and relatively easy to manage. Numerous sources on the internet provide ample training data for tools such as ChatGPT.
Multimodal learning within AI expands the capabilities of machines by training them not just on vast amounts of text, but also on other forms of sensory information like images, videos, or audio files. This approach allows models to discover new patterns and correlations between textual descriptions and associated visual or auditory content.
Multimodal generative AI represents a significant advancement in intelligent systems. For example, in training, multimodal AI models integrate diverse data types, enabling them to accept inputs from multiple modalities and generate outputs in various formats. For instance, the foundational version of ChatGPT – GPT-4 – can process both image and text inputs to generate textual responses. OpenAI's latest model – GPT-4o – can reason across audio, vision, and text in real time, showcasing the evolving capabilities of multimodal AI technologies.
What sets Multimodal AI apart from Multimodal LLMs?
Multi-modal LLMs, or large language models, have recently gained immense significance in revolutionizing our interactions with computers and the internet. With billions of parameters, these models can comprehend and generate text in a manner that closely resembles human language, making them invaluable for a wide range of applications.
Simultaneously, Multi-modal AI has seen rapid advancement, blending various AI modalities such as text, image, audio, and video to create more holistic and human-like AI systems. These systems can process and generate content across multiple modalities, facilitating applications like speech recognition and automated image captioning.
Large Language Models have been transformative in artificial intelligence by enabling human-like text generation and understanding. They are equally pivotal in multi-modal AI as they bridge the gap between textual content and other modalities such as images or videos, resulting in more adaptable and comprehensive AI systems.
The field of artificial intelligence has made significant strides recently, largely propelled by Large Language Models (LLMs) such as GPT-4 and Llama-3, which have garnered substantial attention and have been instrumental in diverse natural language processing (NLP) tasks. However, the integration of these LLMs with other modalities like images or videos has opened up new possibilities.
