What’s the news?

• Leading AI companies are entering a new race to embrace multimodal capabilities.

Central idea

• AI’s next frontier is undoubtedly headed toward multimodal systems, enabling users to interact with AI through various sensory channels. People gain insights and context by interpreting images, sounds, videos, and text, making multimodal AI a natural evolution for comprehensive cognition.

A New Race to Embrace Multimodal Capabilities

• OpenAI, known for ChatGPT, recently announced that GPT-3.5 and GPT-4 models can now understand images and describe them in words.
• Additionally, their mobile apps are equipped with speech synthesis, enabling dynamic conversations with AI.
• OpenAI initially promised multimodality with GPT-4’s release but expedited its implementation following reports of Google’s Gemini, a forthcoming multimodal language model.

Google’s Advantage and OpenAI’s Response

• Google enjoys an advantage in the multimodal realm because of its vast image and video repository through its search engine and YouTube.
• Nevertheless, OpenAI is rapidly advancing in this space. They are actively recruiting multimodal experts, offering competitive salaries of up to $3,70,000 per year.
• OpenAI is also working on a project called Gobi, which aims to build a multimodal AI system from the ground up, distinguishing it from their GPT models.

What is multimodal artificial intelligence?

• Multimodal AI is an innovative approach in the field of AI that aims to revolutionize the way AI systems process and interpret information by seamlessly integrating various sensory modalities.
• Unlike conventional AI models, which typically focus on a single data type, multimodal AI systems have the capability to simultaneously comprehend and utilize data from diverse sources, such as text, images, audio, and video.
• The hallmark of multimodal AI lies in its ability to harness the combined power of different sensory inputs, mimicking the way humans perceive and interact with the world.

The Mechanics of Multimodality

• Multimodal AI Basics: Multimodal AI processes data from various sources simultaneously, such as text, images, and audio.
• DALL.E’s Foundation: DALL.E, a notable model, is built upon the CLIP model, both developed by OpenAI in 2021.
• Training Approach: Multimodal AI models link text and images during training, enabling them to recognize patterns that connect visuals with textual descriptions.
• Audio Multimodality: Similar principles apply to audio, as seen in models like Whisper, which translates speech in audio into plain text.

Applications of multimodal AI

• Image Caption Generation: Multimodal AI systems are used to automatically generate descriptive captions for images, making content more informative and accessible.
• Video Analysis: They are employed in video analysis, combining visual and auditory data to recognize actions and events in videos.
• Speech Recognition: Multimodal AI, like OpenAI’s Whisper, is utilized for speech recognition, translating spoken language in audio into plain text.
• Content Generation: These systems generate content, such as images or text, based on textual or visual prompts, enhancing content creation.
• Healthcare: Multimodal AI is applied in medical imaging to analyze complex datasets, such as CT scans, aiding in disease diagnosis and treatment planning.
• Autonomous Driving: Multimodal AI supports autonomous vehicles by processing data from various sensors and improving navigation and safety.
• Virtual Reality: It enhances virtual reality experiences by providing rich sensory feedback, including visuals, sounds, and potentially other sensory inputs like temperature.
• Cross-Modal Data Integration: Multimodal AI aims to integrate diverse sensory data, such as touch, smell, and brain signals, enabling advanced applications and immersive experiences.

Complex multimodal systems

• Meta introduced ImageBind, a multifaceted open-source AI multimodal system, in May this year. It incorporates text, visual data, audio, temperature, and movement readings.
• The vision is to add sensory data like touch, speech, smell, and brain fMRI signals, enabling AI systems to cross-reference these inputs much like they currently do with text.
• This futuristic approach could lead to immersive virtual reality experiences, incorporating not only visuals and sounds but also environmental elements like temperature and wind.

Real-World Applications

• The potential of multimodal AI extends to fields like autonomous driving, robotics, and medicine. Medical tasks, often involving complex image datasets, can benefit from AI systems that analyze these images and provide plain-language responses. Google Research’s Health AI section has explored the integration of multimodal AI in healthcare.
• Multimodal speech translation is another promising segment, with Google Translate and Meta’s SeamlessM4T model offering text-to-speech, speech-to-text, speech-to-speech, and text-to-text translations for numerous languages.

Conclusion

• The future of AI lies in embracing multimodality, opening doors to innovation and practical applications across various domains.
