What is Promptist?
Promptist is an innovative AI model developed by Microsoft that uses reinforcement learning to automatically optimize text prompts for Stable Diffusion v1.4. It acts as an intelligent interface between users and text-to-image generation models, improving the quality and effectiveness of prompts through learned optimization.
Implementation Details
The model is built on GPT-2 architecture and uses transformers for text generation. It processes user input by appending "Rephrase:" to the prompt and generates optimized versions using beam search with 8 beams and a maximum of 75 new tokens. The implementation includes specialized tokenization with left-side padding and uses the EOS token as the padding token.
