Single modality (unimodal) tasks include implementing the generation of large amounts of data with similar characteristics based on existing data transforming the characteristics or modality of existing data based on a demand. Taking image generation as an example, the training data for a generative model is a single modality. The inputs are the images to be generated or transformed, and the task could be generating a large number of images of similar style based on a specific style of image or transforming a photograph into a certain painting style. The workflow of such a single modality task is shown below.

A multi-modality (multimodal) task generally refers to generating multimodal data with corresponding characteristics based on an input demand. Training data for the generative model contains each modality and its description. The inputs are prompts, such as text-generated images or text-generated audio prompts. Tasks could be generating images or audio based on the input text to generate a corresponding image or audio, or a description based on the image. The workflow of such a multi-modality task is shown below.
