What is this system and what does it run on?
AI
- 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. + This is a self-hosted AI image studio for generative editing, multi-view character rendering, background removal, face swapping, and group-based asset management. It runs on a local RTX A6000 GPU (CUDA 12.4, 48 GB VRAM) using the Qwen 2.5 VL GGUF model (Rapid-NSFW-v23 Q8_0) via ComfyUI. The frontend is a single-page browser app (car.html) talking to a FastAPI backend on :8500.

Walk me through the image generation flow.
AI
- 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. + When a generation is triggered the pipeline is:

+ 1. Prompt cleaning — if the prompt contains "transparent background", that keyword is stripped so Qwen renders a clean solid-BG image instead of producing washed-out halos.

+ 2. ComfyUI queue — the reference image is uploaded to ComfyUI (:8188) and injected into image1. An optional wireframe frame extracted from a pose-guide video goes into image2. The workflow graph (workflow_qwen_edit.json) is patched with the prompt, dimensions, seed, and sampler params, then submitted via POST /prompt.

+ 3. Qwen inference — the GGUF model (≈8 GB VRAM), text encoder (FP8), and VAE decode the latent into a PNG.

+ 4. SAM2 post-processing — if transparent was requested, SAM2 point-prompt segmentation removes the background using 12 foreground seed points (hair → shoes, shoulder / hip lateral spread) and 7 background points (corners + edge midpoints). A coverage sanity check (5–92 %) falls back to rembg if the mask is implausible.

What are the main API endpoints?
AI
- 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. + The FastAPI service (:8500) exposes:

+ GET /images — full image list with PostgreSQL metadata (group, prompt, pose, sort order, archived flag).
+ POST /upload — add an image; with group_id + skip_poses it silently joins an existing group without triggering pose generation.
+ POST /batch — async multi-prompt generation job (filenames, prompts, poses, wireframe_ref). Poll progress via GET /jobs/{id}.
+ POST /faceswap — insightface video face swap with optional GFPGAN restoration.
+ POST /remove-background-sam/{f} — SAM2 BG removal to a .nobg.png sidecar.
+ POST /images/{f}/set-preferred — moves image to group slot 0 and queues face extraction in the background.
+ GET /wireframe/frame/{name}?t= — extract a frame at normalised time t∈[0,1] from a wireframe pose video. +
+
+

How does the face-book and multi-view workflow work?
+
+
+
+
+
AI
+
+ Face-book: marking an image as "preferred" (star button) moves it to sort_order=0 in the group and triggers a background task. insightface detects the largest face, adds 50 % padding on the sides and 200 % headroom above, and saves a {group_id}_face.png crop. This appears as a 72 px thumbnail in the studio Info tab for fast face-reference lookup.

+ Multi-view / camera angles: the Generate tab offers 12 camera angle presets — 8 absolute (Front, ¾ Left/Right, Side, Back, High, Low) and 4 relative (±45°, ±90°). Each fires a /batch request with the angle prompt injected and pose=null. The wireframe pose guide (a .mp4 video scrubbed to any frame) is passed as image2 in the Qwen workflow to constrain body layout without ControlNet — the controlnet model folder is empty by design.

+ Group management: all images belong to groups stored in PostgreSQL. Clipboard paste (Ctrl+V) while a group is open offers "add to this group — no poses" or "new group with pose generation". Archive hides images from the default view without deleting them.
