Multimodal AI

Core concepts Last reviewed 2026-06-11

Definition AI systems that can process and generate more than one type of data—such as text, images, audio, and video—within a single model. A multimodal model can, for example, describe a photograph or read a scanned document.

In more depth

Earlier AI models handled one data type at a time; multimodal models accept mixed input and can reason across formats, such as answering questions about a chart or extracting terms from a scanned exhibit. Major commercial AI assistants are now multimodal by default. For legal work this enables direct analysis of discovery images, recorded audio, and scanned filings, though accuracy on poor-quality scans and handwriting still calls for human checking.
