Technical Implementation

SDXL Refiner

• Integration Point: Added as a post-processing module after the initial image is generated by the Stable Diffusion pipeline.
• Operation:
  1. Takes the intermediate image output and applies targeted refinements to textures, colors, and details.
  2. Leverages a negative prompt pipeline to suppress undesirable styles such as noise, sketch artifacts, and unrealistic deformations.
  3. Adjusts the model’s refinement step ratio dynamically based on user-specified constraints and stylistic requirements.
• Effect: Ensures production-ready outputs by enhancing visual consistency and detail fidelity across generated images.

LLM Query Caching

• Integration Point: Incorporated at the layout generation stage, where textual descriptions are converted into bounding box specifications or layouts by LLMs.
• Operation:
  1. A caching mechanism stores the results of queries to the LLM for specific prompts.
  2. For repeated or similar prompts, the system retrieves pre-computed layouts instead of querying the LLM again.
  3. Implements hashing techniques to uniquely identify prompts, ensuring efficient and collision-free caching.
• Effect:
  • Reduces computational overhead for iterative or batch processing tasks.
  • Improves pipeline efficiency, especially in scenarios requiring real-time feedback or high throughput.
  • Significantly lowers operational costs associated with frequent LLM usage.
