The static workflow JSONs default to CyberRealisticXLPlay (set in an earlier commit), but the KSampler still had euler/normal/CFG7/20 — the generic settings I scaffolded with. Updated to the creator-published defaults: dpmpp_2m_sde / karras / CFG 4 / 28 steps. CLIP skip 1 already correct (no node needed; default behavior). Added a section to the deployment README spelling out the trade-off: static workflows are locked to one checkpoint family at a time because Open WebUI's nodes mapping doesn't expose sampler/CFG/scheduler/CLIP skip/prefix. For multi-checkpoint use, the smart_image_gen Tool path is the only one that gets these right per-prompt. Re-paste workflows into Open WebUI Settings → Images to pick up.

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.
