LLMs (Local Language Models) can enhance local editing capabilities within the Diff-Plugin framework by providing a more granular understanding of user instructions. By incorporating LLMs, the system can better interpret specific details and nuances in text prompts related to localized edits. This allows for more precise adjustments in images, focusing on specific regions or elements as directed by the user. With LLMs, Diff-Plugin can improve its ability to execute intricate editing tasks that require fine-tuned modifications in particular areas of an image.
