OWUI 0.9.6+ regression: Function Calling: Native on huihui_ai/qwen3-vl-abliterated:8b produces empty assistant turns even with enable_thinking=false in custom_params. The model's tool-call output stops being dispatched and the chat completion finishes successfully, so the failure presents as "the model decided not to call the tool" — no error, no tool block, just empty assistant content with follow-up chips. Diagnosed in a live debug session: confirmed Function Calling was Native in the running OWUI, enable_thinking was off, tool still didn't fire; flipping to Default fixed dispatch immediately. This supersedesd8c8421("lock in working config — Native + enable_thinking=false"), which was correct through OWUI 0.9.5 but no longer holds. Returns to the1ed2e72config (Default) for the same fundamental reason: Native does not reliably parse Qwen 3.x output on the current OWUI parser. Trade-off (unchanged from the1ed2e72era): no structured "View Result from edit_image" UI block — tool results render as plain text in the assistant message instead. Kept enable_thinking=false in custom_params. It's no longer strictly required (Default's wrapper doesn't read model thinking output), but it saves the tokens Qwen would otherwise spend on hidden thinking before each dispatch. Updated image_studio.md to match: Function Calling table row, Custom Parameters note, and Qwen-quirk explainer all rewritten; added a new "Open WebUI 0.9.6+ regression" paragraph documenting the empty-turn signature so the failure mode is recognisable without re-deriving it.

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.
