What is Multimodal AI?

Multimodal AI is artificial intelligence that can process multiple types of data or modalities (i.e., modes of communication like text, video, image, or audio). These machine learning models can analyze various types of data—in different forms—to create more comprehensive understanding and output.

Multimodal AI models can move between modalities with ease. For example, a model might generate an image based on text input or vice versa. Multimodal AI also enables models to make stronger informed decisions when analyzing data and generating outputs.

Multimodal AI vs Unimodal AI

The primary difference between unimodal and multimodal AI is their ability to process certain types of data. While multimodal AI can process and create output in several forms, unimodal AI only understands and generates content in one modality, such as video or text. 

This seemingly small difference makes a greater impact on an AI model’s output than you might imagine. With access to data in several modalities, multimodal AI can better understand requests and data, enabling richer outputs for a variety of user needs.

How Multimodal AI Works

Multimodal AI uses large language models (LLMs) and data fusion techniques to process multiple input modalities. A 2022 Cornell paper on multimodal machine learning breaks down the process into three main components:

• Heterogeneity: The many structures and qualities of different modalities
• Connections: Shared qualities between different modalities, such as semantic correspondence or statistical similarities
• Interactions: The ways modalities interact when integrated

Multimodal AI models also utilize natural language processing (NLP) and computer vision technologies. Other tools for quality multimodal AI include text analysis, and resources for storage and computation to enable data mining.

Multimodal AI Use Cases 

Multimodal AI models offer a range of services and tools, with many potential uses. Read on to learn about a few of the most common multimodal AI use cases.

Generative AI

Older AI models often focused on making predictions based on datasets, but generative AI can create new content. Generative AI uses deep learning models to analyze data, “learn” the data, and generate output based on what it sees as a statistically likely response to the input.

Multimodal generative AI models don’t just process multiple modalities of data and provide output based on user requests. These models also learn patterns and associations based on the data and generate feasible responses and content.

Tavus’ conversational video is one example of multimodal generative AI’s capabilities. With Tavus API, developers can integrate tools that allow end users to create digital twins that act as conversational agents. Tavus’ Conversational Video Interface (CVI) makes it possible for talking head agents to speak, see, and hear. The model uses advanced speech recognition, vision, and conversational awareness to enable instant and natural-sounding responses.

Autonomous Vehicles

Driverless cars, or autonomous vehicles, are revolutionizing transportation. Many proponents claim these cars will help make car travel safer, more efficient, and more accessible. 

For autonomous vehicles to work, they need several types of AI, including multimodal AI. Innovators are enhancing autonomous driving with multimodal AI to help these cars gain a more comprehensive understanding of their surroundings. The ability to process multiple modalities enables autonomous vehicles to use cameras, radar, and other forms of data input to improve depth perception and accuracy. Using a wide variety of data enables better awareness and decision-making so passengers can feel confident and safe with AI drivers.

Learning Tools

Multimodal AI has the potential to revolutionize online education with its ability to analyze different learning materials and student responses. Effective teachers interpret students’ facial expressions, tone, and class work to determine their grasp of materials and concepts. This allows teachers to adjust their approach and accommodate different learning styles. 

Online education can make this more difficult, especially since students work with material in various formats. Multimodal AI offers the potential for AI models to conduct analyses similar to how a teacher would—by using student expressions, tones, and text submissions to develop a comprehensive view of each student’s learning process and needs. Multimodal AI can personalize learning paths, provide intelligent tutoring, generate educational content, evaluate and give feedback on assignments, and enhance access to learning materials.

Virtual Assistants 

Multimodal AI has the power to make personal AI assistants more effective. AI virtual assistants use conversational AI models to create agents that can interact with human users in ways that feel natural. With multimodal AI, those conversations become seamless experiences thanks to the model’s ability to process input and generate output in a variety of forms, including voice, chat, and text.

Benefits of Multimodal AI

Multimodal AI offers wide-ranging benefits, from improved performance to increased contextual understanding. Read on to learn more about the ways multimodal approaches are pushing AI technology further.

Greater Accuracy & Performance

Access to data in various forms, including text, image, and video, allows multimodal models to understand input with greater accuracy—enabling better outputs. Multimodal AI can fill information gaps with data from multiple formats, improving its knowledge base and how effectively it interprets and responds to user input.

Tavus’ Phoenix model offers exceptionally realistic and accurate digital twins, making it easier than ever to generate lifelike replicas without sacrificing video quality or performance.

Natural Interactions

Multimodal AI utilizes its access to multiple types of data to generate a comprehensive understanding of user needs. These models don’t just use text or speech input; they can also process data such as facial expressions and gestures to interpret engagement and needs. 

Developers choose Tavus API for this very reason—with an incredibly realistic, interactive experience, Tavus’ conversational AI delivers authentic-sounding AI agents with less than a second of latency.

Challenges of Multimodal AI

AI models are constantly evolving as AI leaders work to improve their functionality and accuracy. Multimodal AI is no different, with innovators facing several challenges:

• Difficulty aligning data: Multimodal AI requires strong datasets, but building such datasets can be challenging. Each mode of data has its own features and requires different steps for cleaning, normalization, and prepping for integration with other modes. Possible solutions include using multimodal transformers to align data or autoencoders to map features of one modality onto another.
• Limited computational resources and infrastructure: Multimodal AI models need vast computational resources and specific infrastructure for training and implementation. Some AI leaders use hardware accelerators or specialized chips to optimize performance.
• Costly and time-consuming training processes: Multimodal AI models require a large amount of data for each AI architecture involved (including transformers, memory networks, and capsule networks). Possible solutions include using modular networks that are trained separately or using hierarchical multimodal networks that process data at multiple levels of abstraction.
• Ethical and privacy-related concerns: Multimodal AI’s need for vast data means models have to pull from several sources, including private data like healthcare records, social media, smartphones, and more. Possible solutions include differential privacy techniques or ethical AI frameworks and regulatory compliance.
