I would like diffusers to operate similarly to a1111. In a1111, the embedding lengths for negative and positive prompts differ without padding. However, upon reviewing the code for diffusers, it seems that padding is applied to all, aligning with the longer prompt. I am wondering if it is possible to proceed without padding in diffusers as well. Could you provide insights on this situation, considering the differences in embedding lengths for negative and positive prompts in a1111 and the padding approach in diffusers?
