Summary of Changes
Hello @OscarSavNS, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request introduces a new docs/architecture-diagram.md file to provide a clear and concise overview of the DiffSynth-Engine's system architecture. The primary goal is to enhance understanding of the codebase by visualizing the engine's components and their interactions through a Mermaid diagram, complemented by a detailed textual explanation of each architectural layer. This addition aims to serve as a valuable resource for developers and contributors to quickly grasp the system's design and flow.
Highlights
- Introduction of a comprehensive architecture diagram: A new Mermaid diagram illustrating the end-to-end flow of the DiffSynth-Engine, from user input and model fetching to the core denoising loop and final image generation. It visually represents the interaction between various components like pipeline types, text/image processing, and noise/sampling setup.
- Detailed textual explanation of architectural components: A detailed textual overview accompanying the diagram, breaking down the architecture into key components such as the Pipeline Layer (e.g., FluxImagePipeline, SDXLImagePipeline), Text Processing, Image Processing, Noise Scheduling & Sampling, Core Denoising (DiT Transformer), Advanced Features (LoRA, IP-Adapter, Parallel Processing, Quantization), and Model Management.

Code Review
This pull request introduces a comprehensive architecture diagram for the DiffSynth-Engine, which is a great addition for understanding the codebase. The Mermaid diagram and the accompanying text provide a clear and detailed overview of the system's components and data flow. My feedback includes a minor suggestion to improve the consistency of the labels in the diagram for better clarity.

For consistency with the other pipeline labels in the diagram (like SDXL, SD, Video, Qwen Image), which refer to the model family or task, consider changing the label for FluxImagePipeline from Text-to-Image to Flux. This would make it clearer that this branch of the diagram corresponds to the Flux model family.

To better understand the codebase I created a system architecture diagram in Mermaid, I PR in case it's desired/useful! Let me know, if something like this is desired, if I should adjust it in any way!
