gpt-author is a creative writing project that leverages the capabilities of GPT-4, Stable Diffusion, and Anthropic API to automatically generate entire original fantasy novels based on user-provided prompts. Users can specify the desired number of chapters, and the AI constructs the narrative, improves upon the plot, writes each chapter sequentially while ensuring continuity, and even designs cover art, ultimately compiling everything into an EPUB file ready for e-book readers. People might want to use it to quickly produce written content for entertainment, personal enjoyment, or to explore AI's potential in creative writing, particularly for crafting long-form stories with minimal human input.
