Two bugs in one screenshot: 1. LLM called edit_image(prompt=..., ...) but the signature was edit_image(edit_instruction=..., ...) — mismatch, missing-arg crash. Renamed the first param to `prompt` so both tools have a matching, predictable name. System prompt updated with an explicit 'do not invent edit_instruction' line for stubborn models. 2. After fix #1, edit_image still couldn't find the prior generated image because Open WebUI assistant-message file attachments only carry {type, url} (no id, no path). _read_file_dict now also greps the file id out of /api/v1/files/<uuid>/content URLs and feeds it to Files.get_file_by_id. Verified pattern matches absolute URLs (https://llm-1.srvno.de/api/v1/files/.../content). System prompt also now says 'including images you previously generated in this chat' to nudge the LLM to pick up assistant outputs as edit candidates.

comfyui-nvidia
ComfyUI image-generation backend, NVIDIA-accelerated, fronted by Open WebUI for multi-user chat and image generation/editing.
Built from the official ComfyUI manual install for
NVIDIA — no
third-party base image. CI publishes the image to
git.anomalous.dev/alphacentri/comfyui-nvidia on every v* tag (see
.gitea/workflows/release.yml).

Deploy
The full stack — Caddy + Ollama + ComfyUI + Open WebUI (+ optional
Anubis) — lives under deployments/ai-stack/.
Bring-up steps, host prerequisites, Open WebUI workflow wiring, and
gotchas are in deployments/ai-stack/README.md.
Replaces
This repo supersedes the previous figment + segment + Forge stack. ComfyUI's node graph covers everything those services provided (txt2img, img2img, inpaint, mask generation via SAM/GroundingDINO custom nodes), and Open WebUI talks to it natively.
