Multimodal AI refers to models and systems that can understand or generate multiple data types. A multimodal assistant might read text, inspect an image, listen to audio, analyze a document, or produce a visual answer.
In practice
This matters because many real workflows are not text-only. Customer support screenshots, invoices, product photos, whiteboards, recordings, and PDFs can all become part of the AI context.
What to watch
Multimodal does not mean the model understands everything perfectly. Visual details, small text, charts, and ambiguous images still need verification.
