Multimodal Model
A multimodal model can process and understand multiple types of input, such as text, images, audio, or video.
A multimodal model is an artificial intelligence system capable of processing and understanding multiple types of input data simultaneously, such as text, images, audio, and video. These models can integrate information across different modalities to perform tasks that require understanding of multiple data types.
Multimodal models work by converting different input types into a common representation space. For example, a model might convert both text and images into embeddings that capture their meaning in a shared vector space. This allows the model to understand relationships between different modalities: it can describe images in text, answer questions about images, or find images matching text descriptions.
Popular multimodal models include GPT-4 Vision (which processes text and images), DALL-E (which generates images from text descriptions), and models like Gemini that handle text, images, audio, and video. These models have enabled new applications like visual question answering (answering questions about images), image captioning (describing images in text), and video understanding.
Multimodal models are more powerful than single-modality models for many tasks because they can leverage information from multiple sources. A model analyzing a document with both text and images can understand the content more completely than one analyzing text alone. However, multimodal models are also more complex to train and require diverse, well-aligned training data across modalities.
As multimodal models become more capable, they're enabling new applications in accessibility (describing images for visually impaired users), content creation, education, and analysis. Understanding multimodal capabilities is increasingly important as AI systems become more sophisticated and integrated into various applications.
