The embodiment of the invention provides an image restoration model training method and device and an image restoration method and device, and belongs to the technical field of artificial intelligence. The method comprises the following steps: acquiring a sample image pair comprising a first sample image and a second sample image, and respectively carrying out image standardization processing on the first sample image and the second sample image to obtain a first standard image and a second standard image; inputting the first standard image into a preset original image processing model; performing up-sampling processing on the first standard image through the up-sampling sub-model to obtain a preliminary image; the image resolution of the preliminary image is higher than that of the second sample image; performing diffusion denoising processing on the initial image through a diffusion denoising sub-model to obtain an intermediate image; calculating target loss data according to the second sample image, the pr
