Multimodal AI

Multimodal AI systems process or generate across multiple data types such as text, images, audio, and video within one model or pipeline.

One system that can work with more than one kind of input or output—words, pictures, sound, video.

Multimodal systems train or fuse across text, image, audio, and video. Architectures may share encoders or align modalities in a joint embedding space.

Many real workflows mix documents, screenshots, and speech—multimodal capability is increasingly a product differentiator.

• Document + screenshot understanding
• Image-conditioned assistants
• Video summarization (emerging)

• Richer context than text-only
• Supports mixed-media enterprise data

• Higher compute cost
• Evaluation is harder across modalities

• Multimodal does not mean unlimited world knowledge
