What is multimodal AI? It’s a question we hear often these days, isn’t it? Whether during lunch breaks, in office chat groups, or while chatting with friends in the evening, it seems that everyone is abuzz with talk of GPT-4.

The recent release of GPT-4 has sparked a flurry of excitement and speculation within the AI community and beyond. As the latest addition to OpenAI’s impressive line of AI language models, GPT-4 boasts a range of advanced capabilities, particularly in the realm of multimodal AI.

With the ability to process and integrate inputs from multiple modalities, such as text, images, and sounds, GPT-4 represents a significant breakthrough in the field of AI and has generated considerable interest and attention from researchers, developers, and enthusiasts alike.

Since GPT-4’s release, everybody is discussing about the possibilities offered by multimodal AI. Let’s shed some light on this topic by going back to 6 months earlier first.

6 months earlier: Discussing multimodal AI

In a podcast interview titled “AI for the Next Era,” OpenAI’s CEO Sam Altman shared his insights on the upcoming advancements in AI technology. One of the highlights of the conversation was Altman’s revelation that a multimodal model is on the horizon.

The term “multimodal” refers to an AI’s ability to function in multiple modes, including text, images, and sounds.

OpenAI’s interactions with humans were restricted to text inputs, be it through Dall-E or ChatGPT. However, a multimodal AI would be capable of interacting through speech, enabling it to listen to commands, provide information, and even perform tasks. With the release of GPT-4, this might change for good.

I think we’ll get multimodal models in not that much longer, and that’ll open up new things. I think people are doing amazing work with agents that can use computers to do things for you, use programs and this idea of a language interface where you say a natural language – what you want in this kind of dialogue back and forth. You can iterate and refine it, and the computer just does it for you. You see some of this with DALL-E and CoPilot in very early ways.

-Altman

Although Altman did not explicitly confirm that GPT-4 would be multimodal in that time, he did suggest that such technology is on the horizon and will arrive in the near future. One intriguing aspect of his vision for multimodal AI is its potential to create new business models that are not currently feasible.

Altman drew a parallel to the mobile platform, which created countless opportunities for new ventures and jobs. In the same way, a multimodal AI platform could unlock a host of innovative possibilities and transform the way we live and work. It’s an exciting prospect that underscores the transformative power of AI and its capacity to reshape our world in ways we can only imagine.

…I think this is going to be a massive trend, and very large businesses will get built with this as the interface, and more generally [I think] that these very powerful models will be one of the genuine new technological platforms, which we haven’t really had since mobile. And there’s always an explosion of new companies right after, so that’ll be cool. I think we will get true multimodal models working. And so not just text and images but every modality you have in one model is able to easily fluidly move between things.

-Altman

A truly self-learning AI

One area that receives comparatively little attention in the realm of AI research is the quest to create a self-learning AI. While current models are capable of spontaneous understanding, or “emergence,” where new abilities arise from increased training data, a truly self-learning AI would represent a major leap forward.

OpenAI’s Altman spoke of an AI that can learn and upgrade its abilities on its own, rather than being dependent on the size of its training data. This kind of AI would transcend the traditional software version paradigm, where companies release incremental updates, instead growing and improving autonomously.

Although Altman did not suggest that GPT-4 will possess this capability, he did suggest that it is something that OpenAI is working towards and is entirely within the realm of possibility. The idea of a self-learning AI is an intriguing one that could have far-reaching implications for the future of AI and our world.

The release of GPT-4 and the ongoing competition among tech giants highlights the growing importance of AI and its potential to transform the way we interact with technology.

To better understand the topic, we invite you to delve into a deeper and more technical discussion of multimodal AI.

What is multimodal AI?

Multimodal AI is a type of artificial intelligence that has the ability to process and understand inputs from different modes or modalities, including text, speech, images, and videos. This means that it can recognize and interpret various forms of data, not just one type, which makes it more versatile and adaptable to different situations. In essence, multimodal AI can “see,” “hear,” and “understand” like a human, allowing it to interact with the world in a more natural and intuitive way.

Applications of multimodal AI

The abilities of multimodal AI are vast and wide-ranging. Here are some examples of what multimodal AI can do:

• Speech recognition: Multimodal AI can understand and transcribe spoken language, allowing it to interact with users through voice commands and natural language processing.
• Image and video recognition: Multimodal AI can analyze and interpret visual data, such as images and videos, to identify objects, people, and activities.
• Textual analysis: Multimodal AI can process and understand written text, including natural language processing, sentiment analysis, and language translation.
• Multimodal integration: Multimodal AI can combine inputs from different modalities to form a more complete understanding of a situation. For example, it can use both visual and audio cues to recognize a person’s emotions.

How does multimodal AI work?

Multimodal neural networks are typically composed of several unimodal neural networks, with an audiovisual model being an example of two such networks – one for visual data and one for audio data. These individual networks process their respective inputs separately, in a process known as encoding.

Once unimodal encoding is completed, the extracted information from each model needs to be combined. Various fusion techniques have been proposed for this purpose, ranging from basic concatenation to the use of attention mechanisms. Multimodal data fusion is a critical factor in achieving success in these models.

After fusion, the final stage involves a “decision” network that accepts the encoded and fused information and is trained on the specific task.

In essence, multimodal architectures consist of three essential components – unimodal encoders for each input modality, a fusion network that combines the features of the different modalities, and a classifier that makes predictions based on the fused data.

Comparison with current AI models

Compared to traditional AI models that can only handle one type of data at a time, multimodal AI has several advantages, including:

• Versatility: Multimodal AI can handle multiple types of data, making it more adaptable to different situations and use cases.
