Prometheus is presumed to be the first full rank finetune of Playground v2.5, developed by the creator of the Proteus model. This text-to-image generation model has been specifically adapted to enhance accessibility for the open-source community.
Key Features and Considerations
Presumed First Full Rank Finetune of Playground v2.5:
- Complete parameter update of Playground v2.5 architecture
- Unique approach to fine-tuning this particular base model
Enhanced Accessibility:
- Custom sampling methods have been removed through brute force techniques
- Designed to be more compatible with standard open-source tools and workflows
- post processing applied to ensure backwards compatibility with most SDXL LoRAs and tools
Output Characteristics:
- Aims to provide a balance between consistency and diversity in outputs
- May exhibit some stylistic tendencies inherited from the training process
Training Approach:
- Utilizes the extensive Proteus datasets of over 400,000 images
- Brute force at scale training methodology
- Focused on maintaining model capabilities while increasing compatibility
Advanced Custom CLIP Integration:
- Incorporates a meticulously trained custom CLIP model
- Steadily developed over an extended period
Further fine-tuned for specific qualities in Proteus and Prometheus
- Requires a clip skip setting of 2 for optimal performance
