Vision-Language Model (VLM)

A model that jointly understands images and text, for tasks such as visual question answering and captioning.

Definition

VLMs typically pair a vision encoder, often a vision transformer, with a language model through a projection layer. They power document understanding, chart reading and image-based chat.

Exam tip

VLMs answer questions about images; pure image classifiers only assign labels.
