This system implements a headless image editing API using the Qwen-Rapid-NSFW-v23 model on an RTX A6000 GPU. It provides an HTTP service that accepts image and prompt inputs, processes edits using ComfyUI backend, and returns edited PNG outputs.

The system consists of two main components: a ComfyUI backend (running on port 8188) that executes the Qwen models and a FastAPI service (running on port 8500) that provides HTTP API endpoints. When you send an image and prompt to the API, it forwards the request to ComfyUI which processes the image using the Qwen-Rapid-NSFW-v23 model with specific workflow parameters.

Key components include:

- Qwen model: Qwen-Rapid-NSFW-v23_Q8_0.gguf
- Text encoder: qwen_2.5_vl_7b_fp8_scaled.safetensors
- VAE decoder: qwen_image_vae.safetensors
- Workflow execution engine using ComfyUI

The system uses a specialized workflow (workflow_qwen_edit.json) that defines the processing pipeline with nodes for loading the model, text encoder, VAE, input image, positive/negative prompts, latent generation, sampling, and output saving.
