Multimodal AI

Models that see, hear, and read at once.

Multimodal AI describes models that take in and reason across more than one kind of data — text, images, audio, and video — in a single system, aligning those modalities so the model can answer about an image, transcribe and act on speech, or ground a response in a chart.

Multimodal is a description of inputs and outputs, not a promise that every kind of signal is supported. The GPT-4 technical report, for example, describes image and text inputs with text output (OpenAI, GPT-4 Technical Report). For a document-reading application, write down which evidence the system must use: the words in a table, the table's layout, or a chart beside it. Then test those cases separately instead of assuming a model that accepts an image will interpret every detail correctly.

Tormod Ree in episode 70 describes combining cameras and microphones in a meeting room; episode 5 with Chip Huyen and Vivienne Zhang covers evaluation challenges for generative and multimodal systems. What is multimodal AI? explains the term, while can a language model control a robot? follows perception into action. The edge AI definition covers a separate decision: where that processing happens.
