Multimodal AI

Multimodal AI refers to models that can process and generate more than one type of data — such as text, images, audio, and video — within a single system. A multimodal model can, for example, look at an image and answer questions about it, or turn a text prompt into a video.

How it works

Multimodal models are trained on paired data across modalities so they learn shared representations — linking the word “dog,” a photo of a dog, and the sound of barking. Leading 2026 foundation models are natively multimodal, handling text, images, and audio in one model.

Why it matters

Multimodality expands AI from text into the visual and audio world. The MMMU benchmark, which tests multimodal reasoning, saw scores jump 18.8 points in a single year. See AI Models & Benchmarks Statistics 2026.
