Sudowrite's Muse model trained on published works being the Purple Prose Poet is a meaningful distinction for literary fiction
Muse 1.5 being highlighted as a major improvement for drafting fiction with its training on published works is the quality argument. Training on published literary fiction rather than on web content produces different prose characteristics: more attention to sentence rhythm, more nuanced character interiority, more literary imagery. Whether those characteristics match your creative voice is the relevant evaluation question.
The Purple Prose Poet label being used by Sudowrite themselves is the honest self-characterisation that sets the right expectations. Models trained on literary fiction will produce more ornate, more lyrical, more stylistically rich prose than models trained on web content or general text. For some writers that is exactly what they want. For writers working in a spare, minimalist style it may require significant editing.
The advanced AI models tuned for literary and creative writing being the core differentiation is what makes Sudowrite specifically useful for literary fiction rather than the general creative writing category.
Does your fiction writing style tend toward the lyrical and ornate or the spare and minimalist and has that affected how useful you find Muse-generated suggestions?
