The next frontier in AI: Understanding multimodal AI systems

Generative AI is poised to be a $1.3 trillion market by 2032.  

GenAI has become essential due to its ability to automate creativity, enhance personalization, and drive efficiency. By generating realistic text, images, and videos, it is revolutionizing industries like media, healthcare, and retail. Its capability to analyze vast datasets and create tailored outputs enables businesses to deliver hyper-personalized experiences. Automation also helps reduce costs and time. This transformative potential makes generative AI a cornerstone of innovation in the modern digital landscape.

ChatGPT has showcased the potential of GenAI in transforming business processes and delivering intelligent solutions. It is widely being used in customer support, content creation, and education. ChatGPT provides human-like text responses to queries and aids in writing, summarizing, or brainstorming ideas. 

Multimodal AI takes GenAI up a notch. It can solve problems that require information from various sources. For instance, in autonomous vehicles, it processes sensor data, images, and maps simultaneously. In media, it integrates text, visuals, and videos to create immersive content. This capability makes it more versatile for real-world, complex scenarios than single-modal GenAI systems.

In this blog, we will understand multimodal AI systems a little better, gaining a more comprehensive overview of how it works, its many applications, and how multimodal systems work. 

 

Multimodals that multitask: AI can see, hear, and create all at once 

OpenAI’s ChatGPT, launched in November 2022, marked a significant milestone in generative AI by offering human-like conversational capabilities through natural language processing (NLP). While ChatGPT was primarily unimodal—processing and responding to text inputs—it paved the way for more advanced systems capable of handling multiple modalities.

Multimodal AI takes this innovation a step further by integrating and interpreting diverse data types, such as text, images, audio, and video. This multisensory capability enables it to generate text, create visuals, synthesize speech, and even produce video content, all informed by a unified understanding of the input data.

The integration of various modalities makes multimodal AI more robust and adaptable. By capturing deeper context and reducing ambiguities, it delivers more accurate and reliable outputs. For instance, DALL·E was OpenAI’s early example of multimodal AI, designed to create images from text prompts. More recently, GPT-4 introduced multimodal capabilities to ChatGPT, allowing it to process and respond to both text and image inputs seamlessly.

This multisensory approach offers significant practical advantages. If one type of input is unavailable or unreliable, multimodal AI can rely on other modalities to maintain performance, ensuring resilience in real-world applications. This adaptability and versatility position multimodal AI as a critical tool for businesses seeking to harness the full potential of their data.

 

How does the multimodal model work?

The process begins with the individual unimodal neural networks which are trained on their respective input data, and are either convolutional neural networks for images or recurrent neural networks for text. These networks output is a set of features that capture the salient characteristics of the input. To achieve this, they are composed of three main components, starting with the unimodal encoders. Encoders separately process all the input data from each modality. In other words, an image encoder should encode an image, and a text encoder should encode text. 

 

Real-world use cases of multimodal AI systems

Multimodal AI has an array of applications. In healthcare, multimodal AI is analyzing a combination of patient data – clinical notes and radiology images to lab results and even genetic information. The technology is transforming healthcare with more accurate diagnosis and personalized treatment plans.

The high-tech systems are a game-changer in the retail industry too. They help retailers enhance customer experience through hyper-personalised recommendations and improve inventory management. By predicting demands from consumers, these systems optimize the performance of inventory by reducing waste and improving productivity. Multimodal AI is transforming media and communication by integrating various data types like text, images and videos to enhance content creation.

Google’s Gemini – A remarkably flexible multimodal AI

In December 2023, Google unveiled Gemini 1.0, an advanced multimodal AI model designed to deliver significant benefits across industries and use cases. Positioned as one of the most capable and versatile AI models to date, Gemini excels in combining diverse data types, including text, images, code, audio, and video, to provide a unified and comprehensive understanding of complex inputs.

What sets Gemini apart is its flexibility and scalability. The model is designed to operate seamlessly across various platforms, from high-performance data centers to mobile devices, enabling businesses to leverage its capabilities regardless of infrastructure constraints.

Gemini’s capabilities are underpinned by rigorous testing against industry benchmarks, such as HumanEval, a standard for evaluating coding performance, and Natural2Code, Google’s proprietary dataset for advanced coding tasks. This ensures the model’s precision and effectiveness in handling sophisticated challenges, particularly in domains like software development, content generation, and cross-platform applications.

By integrating multiple sensory inputs into a cohesive system, Gemini enhances decision-making, reduces ambiguities, and offers actionable insights, making it an invaluable tool for businesses aiming to stay ahead in an increasingly data-driven world.

Meta’s SeamlessM4T – The perfect tool enhancing communication

In August 2023, Meta launched SeamlessM4T, which is the first all-in-one multimodal and multilingual AI translation model. Using SeamlessM4T people can communicate seamlessly by speech and text across any language. SeamlessM4T supports almost 100 languages and it translates 100 input and output languages through speech-to-text. Meta has also launched an open multimodal translation dataset including 270,000 hours of mined speech and text alignments which SeamlessM4T integrates. Such integration results in increased efficiency and quality of the translation process.

A guide to make your multimodal AI journey seamless

To implement multimodal AI successfully within your processes, a robust strategy is key. Here are some key pointers that can make your journey hassle-free. 

1. Identify your data needs and goals – Begin by evaluating your company’s current data infrastructure to ensure that your current systems can handle the immense storage, processing, and integration requirements of diverse types of data. This will vary for text and audio compared with images and videos. This will help define your multimodal AI objectives further enabling your implementation strategy.
2. Have a diverse data repository – For your multimodal AI model to work, you need to be able to source various types of data. This includes customer feedback, product images, training videos, transactional data – the list goes on. It is essential to ensure that this data is high quality. This data also needs to be labelled and compliant with privacy regulations before allowing an AI system to process it.
3. Gather your tech and frameworks – A solid multimodal AI system requires well-configured technology infrastructure, including powerful computers and cloud resources that can merge data from various sources and modalities into a unified system.
