FAQ

Q1: How does Muse compare to other state-of-the-art models in text-to-image generation?

A1: Muse demonstrates superior performance in both image quality and semantic understanding compared to other models like Dali, Dali 2, and Imagine. It outperforms stable diffusion models while providing significantly faster inference.

Q2: Can Muse handle large-scale changes in text prompts and generate diverse images?

A2: While Muse excels in generating images based on small changes in text prompts, it currently faces limitations when it comes to larger changes and drastic transformations. The optimization process during editing might only allow for local changes rather than global transformations.

Q3: How does Muse handle the background when not specified in the text prompt?

A3: In cases where the background is not specified, Muse tends to generate random scenes like beaches, mountains, or other general backgrounds. The underlying latent space dominates the codebook and influences the background generation process.

Q4: Can Muse generate images in the style of new or unknown artists?

A4: Currently, Muse is trained on a dataset biased towards famous artists' styles. Generating images in the style of new or unknown artists would require fine-tuning the model with specific examples of the desired style.

Q5: Is Muse limited to generating text-to-image translations, or can it also generate images based on other prompts?

A5: While Muse was designed specifically for text-to-image generation, it is possible to explore its potential for generating images based on different types of prompts. However, the performance and success might vary depending on the nature of the input prompts.
