The lower the FID, the better it is. Several things can influence FID here:
Number of images (both real and fake)
Randomness induced in the diffusion process
Number of inference steps in the diffusion process
The scheduler being used in the diffusion process
For the last two points, it is, therefore, a good practice to run the evaluation across different seeds and inference steps, and then report an average result.
