d935e24624 Add text-targeted inpainting via GroundingDINO+SAM (mask_text param)
All checks were successful
release / Build & Push Docker Image (push) Successful in 44s
Five pieces:

1. Dockerfile installs storyicon/comfyui_segment_anything (GroundingDINO
   + SAM-HQ in one bundle) into custom_nodes and pip-installs its
   requirements at build time. Model weights auto-download to the
   comfyui-models volume on first inpaint (~3 GB one-time cost).

2. install-custom-node-deps.sh — entrypoint wrapper that pip-installs
   requirements.txt for any custom_node present at startup. Lets users
   add custom nodes via ComfyUI-Manager (or by git-cloning into the
   volume) and have the deps picked up on the next restart, without
   editing the Dockerfile.

3. smart_image_gen v0.6: edit_image gains a `mask_text` param. When
   set, builds an inpainting workflow (LoadImage → GroundingDinoSAM
   Segment → SetLatentNoiseMask → KSampler) so only the named region
   is repainted. When unset, falls through to the existing img2img
   path. Denoise default switches: 1.0 with mask_text (full repaint
   within mask), 0.7 without.

4. Image Studio system prompt teaches the LLM the LOCAL vs GLOBAL
   distinction — set mask_text whenever the user names a specific
   object/region ('the ball', 'the dog', 'the sky'); leave it unset
   only for whole-image style/lighting transformations.

5. Deployment README documents the new mode + the first-inpaint
   weight-download caveat.

Image rebuild required — bump tag to pick up the Dockerfile change.

7c7897818e Image Studio: bake tool_choice=required into the preset
Without it, abliterated/reasoning models like huihui_ai/qwen3.5-
abliterated:9b reliably choose to write a planning response instead
of calling the tool — even with /no_think and a terse imperative
system prompt. tool_choice=required is passed through to Ollama's
chat API and removes the model's option to respond in text at all,
forcing exactly one tool call per turn.

Confirmed working with the abliterated Qwen 3.5 9B base.

a1fca4d5d9 Image Studio: default base model → huihui_ai/qwen3.5-abliterated:9b
Re-imports of image_studio.json kept reverting the base model back to
mistral-nemo:12b because that was still hard-coded in the JSON.
Updated the JSON, the markdown setup table, and the vision-capability
section to lead with the Qwen 3.5 abliterated 9B preset.

Re-ordered the markdown's vision section: shipped default first
(Qwen 3.5 abliterated, with the /no_think + enable_thinking caveat
called out explicitly), alternatives (qwen2.5vl:7b, llama3.2-vision,
minicpm-v) second, non-vision fallback third.

0b1c2ee5b5 Image Studio: tighten system prompt, add /no_think for Qwen 3.x
User reported the model writing a multi-paragraph 'editing plan'
instead of calling edit_image, only firing the tool when explicitly
told to. Two underlying causes:

  1. The previous system prompt was conversational ('ALWAYS / NEVER'
     lists with discussion) — Qwen-style models read that as topics
     to think about rather than rules to obey. Replaced with terse,
     imperative dispatcher framing: 'You do not respond in prose.
     Every user message MUST result in exactly one tool call.'

  2. Qwen 3.x ships with thinking mode on by default. Reasoning
     models almost universally degrade native function calling — they
     plan how to use a tool instead of just calling it. Prepended
     /no_think (Qwen 3.x recognises this token and skips reasoning).
     No-op for non-Qwen-3 base models.

Removed the long after-action paragraph that encouraged elaborate
follow-ups; replaced with 'at most one short sentence'.

5a34ced8f1 Add S3 mirror path for Ollama models + mirror-ollama-model.sh helper
Three pieces:

1. mirror-ollama-model.sh — run on any machine that has the model
   pulled. Parses the manifest at
   ~/.ollama/models/manifests/registry.ollama.ai/<ns>/<name>/<tag>,
   greps every sha256:* digest, tars manifest + referenced blobs into
   one .tgz. Output is portable — extract over any other Ollama
   data dir and the model is immediately visible.

2. init-models.sh gains an s3_pull function that curls a tarball from
   $S3_OLLAMA_BASE and extracts into /root/.ollama/models/. Falls back
   to ollama pull when S3_OLLAMA_BASE is unset, so s3_pull lines are
   safe to commit before the bucket is ready. huihui_ai/qwen3.5-
   abliterated:9b promoted to s3_pull as the example.

3. docker-compose.yml model-init service propagates S3_OLLAMA_BASE
   from .env. Curl auto-installs at script start because ollama/ollama
   doesn't always ship it.

README documents the mirror workflow under "Mirroring models to S3".

f77f5993fb Image Studio: enable vision capability + document upgrade path
Open WebUI was blocking image attachments to the Image Studio model
because mistral-nemo:12b isn't vision-capable. Two changes:

  - capabilities.vision flipped to true in the preset JSON. The Tool
    only needs the image to make it through __messages__ / __files__
    to call edit_image; the actual visual processing happens in
    ComfyUI's img2img, not in the LLM. Setting the flag unlocks the
    attach-image UI without lying about what mistral-nemo can do.

  - System prompt now tells the LLM explicitly: "you may not be able
    to visually inspect the attached image — that is fine. Trust the
    user's description and call edit_image." Prevents the LLM from
    refusing or hedging when it gets an image it can't see.

Documented the upgrade path in image_studio.md for users who want
real vision (qwen2.5vl:7b, llama3.2-vision:11b, minicpm-v:8b — pick
one, add to init-models.sh, swap base_model_id in the preset). The
vision LLM can then write smarter edit_image calls from the image
content rather than the user's description alone.

b604e3f509 smart_image_gen v0.5: surface images via files event (canonical path)
The data-URI message-event approach didn't render — Open WebUI's chat
frontend ignores data URIs from tool-emitted message events because
the markdown-base64 rewriter (utils/files.py convert_markdown_base64
_images) only runs on assistant streaming content, not on tool emits.

Switched to the path Open WebUI's own image-generation flow uses
(backend/open_webui/utils/middleware.py ~1325):

  1. Upload image bytes via open_webui.routers.files.upload_file_handler
     (gets back a file_item with id)
  2. Resolve the served URL via request.app.url_path_for(
     "get_file_content_by_id", id=file_item.id) → /api/v1/files/{id}/content
  3. Emit a `files` event:
        {"type": "files", "data": {"files": [{"type": "image", "url": ...}]}}

Tools now take __request__, __user__, __metadata__ params for the
upload (Open WebUI auto-injects these). Falls back to data-URI
message event if the runtime imports aren't available (e.g. running
the file standalone for tests). The internal upload bypasses
get_verified_user via the user= kwarg, so no token plumbing.

4d996e1205 smart_image_gen v0.4: emit image to chat, return only confirmation
The data URI returned from the tool was being given to the LLM as the
tool result — the LLM then either echoed the base64 to the user as
plain text (screenshot 1) or hallucinated a description of what it
thought the image looked like (screenshot 2 — "an image of a cat
sitting on a windowsill" for a fox-warrior prompt).

Fix: push the markdown image into the chat directly via
__event_emitter__ as a "message" event, and return a short text
confirmation as the function value. The confirmation is worded to
prevent the LLM from describing the image or repeating the markdown
(both common failure modes for tool-using LLMs).

Both generate_image and edit_image fixed.

6adf133558 Ship Image Studio as importable JSON in addition to markdown walkthrough
Open WebUI accepts a JSON file at Workspace → Models → Import that
seeds a new model preset in one click instead of the manual table-
driven setup. The new image_studio.json mirrors the Open WebUI bulk-
export schema (array wrapper around the model object with id, name,
base_model_id, params, meta) and pre-fills system prompt, native
function calling, temperature 0.5, top_p 0.9, smart_image_gen tool
attachment, suggestion prompts.

The markdown walkthrough stays as the source of truth for the system
prompt content and as the fallback when import fails (e.g. tool ID
mismatch, unfamiliar field, schema drift across Open WebUI versions).
README points at both paths.

Caveat doc'd in the markdown: if the imported preset doesn't actually
have smart_image_gen attached, the tool ID in the JSON didn't match
what Open WebUI assigned — re-attach manually in the model edit
screen.

d4e2058859 smart_image_gen v0.3: add edit_image (img2img) method
The Tool now exposes two methods the LLM picks between based on whether
the user attached an image:

  generate_image — txt2img (existing, unchanged behavior)
  edit_image     — img2img on the most recently attached image

edit_image extracts the source image from __messages__ (base64 data
URIs in image_url content blocks) or __files__ (local path or URL),
uploads to ComfyUI's /upload/image, runs an img2img workflow at the
caller-specified denoise (default 0.7), and returns the edited result.
Same per-style routing / sampler / CFG / prefix logic as generation.

Refactored the submit-and-poll loop into _submit_and_fetch shared by
both methods. Image extraction is defensive — tries messages first,
then files (path then URL), returns a clear "no image attached"
message rather than silently generating from scratch.

Image Studio system prompt rewritten to teach the LLM when to call
edit_image vs generate_image and how to pick denoise.

41d571d8d1 Add Image Studio model preset — forces smart_image_gen tool use
A documented Open WebUI custom-model preset wrapping mistral-nemo:12b
with: aggressive system prompt that mandates calling generate_image,
only the smart_image_gen tool attached, native function calling,
lower temperature for tool-call reliability. Users pick "Image Studio"
from the chat-model dropdown when they want images.

Solves the common case where general-purpose chat models describe an
image in text instead of firing the tool — usually on conversational
phrasings like "can you draw me…". The preset removes the ambiguity
by giving the LLM exactly one job and one tool.

Setup walkthrough in openwebui-models/image_studio.md; deployment
README §9 points users at it as the recommended path.

9e22de0328 smart_image_gen: tighten docstring + Literal style enum
Two changes to make the LLM more likely to call the tool:

1. Lead the docstring with an unambiguous directive — "Create an image
   and show it to the user. Use this whenever the user asks you to
   draw, generate, ..." plus a hard "do not say you cannot generate
   images" line. Open WebUI feeds the docstring straight to the LLM as
   the tool description; first line carries the most weight.

2. `style: Optional[StyleName]` where StyleName is a Literal enum of
   the seven values. Native function-calling models read the type
   annotation and present the seven valid values to the LLM as a
   strict choice instead of a free-text param.

If the LLM still doesn't fire the tool, the install is probably wrong:
Workspace → Models → the model → Advanced Params → Function Calling
must be set to Native (not Default).

b815cd6a5f Tune static workflows to CyberRealisticXL recommended settings
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.

45d5541be0 smart_image_gen v0.2: per-style sampler/CFG/steps/CLIP-skip + prompt prefixes
Researched each of the seven SDXL checkpoints on Civitai and encoded the
creator-recommended generation defaults per style instead of one global
set. Material differences:

  - photo (CyberRealistic): dpmpp_2m_sde / karras / CFG 4 / 28 steps / CLIP 1
  - juggernaut: dpmpp_2m_sde / karras / CFG 4.5 / 35 steps / CLIP 1
  - pony: euler_a / normal / CFG 7.5 / 25 steps / CLIP 2
  - general (Talmendo): dpmpp_2m / karras / CFG 8 / 30 steps / CLIP 2
  - furry-nai (Reed): euler_a / normal / CFG 5 / 30 steps / CLIP 2
  - furry-noob (IndigoVoid): euler_a-only / normal / CFG 4.5 / 20 / CLIP 2
  - furry-il (NovaFurry): euler_a / normal / CFG 4 / 30 steps / CLIP 2

Three prompt-prefix dialects auto-prepended (NEVER cross-contaminated):
photoreal models get nothing, Pony gets the full
score_9..score_4_up chain (mandatory), and the NoobAI/Illustrious
furry models get their booru quality + year-tag prefixes
(masterpiece/best quality/absurdres/newest/etc). Workflow now includes
a CLIPSetLastLayer node so per-style CLIP skip works.

Routing default for generic "furry" flipped from Reed (NAI) to NovaFurry
(Illustrious) — current sweet-spot consensus. Removed global
DEFAULT_STEPS/DEFAULT_CFG valves; per-style values are canonical.

Sources: each model's Civitai page (CyberRealisticXL, Juggernaut,
Pony V6 XL, TalmendoXL, Reed FurryMix, IndigoVoid FurryFused,
NovaFurryXL) and Pony/Illustrious prompting guides.

cd0034cd99 Flesh out per-style negatives in smart_image_gen Tool
Each style now gets a proper baseline covering quality, anatomy, and
watermark/signature suppression — plus the appropriate style-leak guards
(no-cartoon for photo, no-human for furry, score_4–6 suppression for
pony). Quality terms only; no NSFW filtering by default since several
checkpoints in this set are commonly used for adult work and would
fight a baked-in content filter. If SFW-by-default is wanted, add an
explicit safe-mode flag rather than expanding NEGATIVES.

c585e53ed4 Bake quality-focused default negatives into the static workflows
Open WebUI overwrites node 7's text when the request supplies a
negative_prompt, so the default only takes effect when one isn't
provided — which is the common case for the image-button path since the
chat UI doesn't expose the field. Generic quality terms only (no style
or content restrictions) so the default is safe across SD/SDXL/Flux
swaps and doesn't fight whichever checkpoint is loaded.

The smart_image_gen Tool already had per-style defaults; this only
affects the non-Tool image-gen path.

392b26167f Add smart_image_gen Tool for per-prompt checkpoint routing
Open WebUI Tool the LLM invokes instead of the built-in image action.
Auto-routes among the seven SDXL checkpoints (photo / juggernaut /
pony / general / furry-{nai,noob,il}) based on either an explicit
`style` arg or first-match-wins regex over the prompt. Constructs the
ComfyUI workflow inline, submits via /prompt, polls /history, returns
the result as a base64 data-URI markdown image so no extra hosting is
needed. Per-style default negatives. ComfyUI URL / steps / CFG /
timeout are admin-tunable Valves.

Filters can't see image-gen requests in Open WebUI (the routers skip
the filter chain), so the LLM-driven Tool is the only path that
gives intent-aware routing without changing the chat UX.

## 8. (Optional) Install the smart-routing Tool
The image-button path always uses the admin's **Default Model**. To get
per-prompt checkpoint routing — e.g. "draw me a cyberpunk city" picks
CyberRealistic, "anthro fox warrior" picks one of the furry checkpoints —
install the `smart_image_gen.py` Tool. It exposes two methods the LLM
calls:
- **`generate_image`** for new images from scratch (txt2img).
- **`edit_image`** for modifying an image the user attached to the
chat. Two modes:
- With `mask_text` — text-targeted inpainting via GroundingDINO+SAM
(e.g. "the dog's collar"). Only the named region is repainted.
- Without `mask_text` — full img2img which reimagines the whole
image at the requested denoise.
Both auto-route to the right SDXL checkpoint per request.
> **First inpaint takes a few minutes**: SAM-HQ (~2.5 GB) and
> GroundingDINO (~700 MB) auto-download into the `comfyui-models`
> volume on the very first call to `edit_image` with `mask_text`.
> Subsequent inpaints are instant.
1. **Workspace -> Tools -> +** (top-right).
2. Paste the contents of
[`openwebui-tools/smart_image_gen.py`](openwebui-tools/smart_image_gen.py).
3. Save. Optionally adjust the Valves (ComfyUI URL, default steps, CFG,
timeout) via the gear icon.
4. **Workspace -> Models** (or pick an existing chat model) -> edit ->
under **Tools**, enable `smart_image_gen` -> save.
5. Make sure the model has **native function calling** enabled
(Workspace -> Models -> the model -> Advanced Params -> Function
Calling: Native). Mistral, Qwen, and Llama 3.1+ all support this.
In a chat with that model, ask for an image — "make me a photoreal
portrait of a cyberpunk samurai" — the LLM should call
`generate_image(prompt=..., style="photo")`. The status bar shows
"Routing to photo (CyberRealisticXLPlay…)" while it generates.
If the LLM responds in text instead of calling the tool, install the
**Image Studio** chat-model preset (next section) — a dedicated model
with a system prompt that removes the ambiguity.
## 9. (Recommended) Install the Image Studio model preset
General-purpose chat models often "describe" an image in text instead
of firing the `generate_image` tool, especially on conversational
phrasing ("can you draw me…", "I'd love a picture of…"). The
**Image Studio** preset wraps `mistral-nemo:12b` in a system prompt
that mandates tool use — every message is treated as an image request.
Setup — two paths:
- **Import the JSON** (fast): Workspace → Models → Import →
[`openwebui-models/image_studio.json`](openwebui-models/image_studio.json).
- **Manual** (full control): walkthrough in
[`openwebui-models/image_studio.md`](openwebui-models/image_studio.md).
Users then pick **Image Studio** from the chat-model dropdown when
they want to generate or edit images.
The preset ships with `vision: true` so users can attach images for
editing even though `mistral-nemo:12b` isn't a vision model — see the
[**Vision capability** section in image_studio.md](openwebui-models/image_studio.md#vision-capability)
for the trade-offs and the upgrade path to a real vision LLM
(`qwen2.5vl:7b`, `llama3.2-vision:11b`, etc.) if the LLM needs to
actually see the image to write smarter edit instructions.
To extend (new checkpoint, new style):
- Add the filename to `comfyui-init-models.sh` so it gets pulled.
- Add a key to the `CHECKPOINTS` dict in `smart_image_gen.py`.
- Optionally add style-specific negatives to `NEGATIVES`.
- Optionally add keyword routing rules to `ROUTING_RULES` for the
auto-detect path.
- Re-paste the Tool source in Workspace -> Tools.
## Mirroring models to S3
For models you want to pin against upstream changes (or pull faster
from your own infra), mirror them to S3 once and have the
deployment fetch from there.
### Create the mirror tarball
Run [`mirror-ollama-model.sh`](mirror-ollama-model.sh) on any machine
that has the model pulled locally. It reads `~/.ollama/models/`,
pulls the manifest's referenced blobs, and tars everything together:
```sh
./mirror-ollama-model.sh huihui_ai/qwen3.5-abliterated:9b qwen3.5-abliterated-9b.tgz
```
### Upload to S3
Whatever fits — `aws s3 cp`, `mc`, `rclone`, etc. The bucket needs
to expose the file over HTTPS (public-read ACL on the object, a
CloudFront distribution, R2 with public URLs, etc.):
```sh
aws s3 cp qwen3.5-abliterated-9b.tgz s3://your-bucket/ollama-models/ --acl public-read
```
### Wire the deployment to fetch from there
In `.env`:
```
S3_OLLAMA_BASE=https://your-bucket.s3.amazonaws.com/ollama-models
```
In `init-models.sh`, switch the affected models from `pull` to
`s3_pull`:
```sh
s3_pull "huihui_ai/qwen3.5-abliterated:9b" "qwen3.5-abliterated-9b.tgz"
```
`docker compose up -d model-init` re-runs the init container; the
script downloads the tarball, extracts into the `ollama-data` volume,
and the running Ollama daemon picks it up on its next manifest scan.
If `S3_OLLAMA_BASE` isn't set, `s3_pull` transparently falls back to
`ollama pull` — safe to commit `s3_pull` lines without S3 ready yet.

**If you change the admin's Default Model to a different checkpoint
family** (Pony, NoobAI, Illustrious, etc.), edit the workflow JSONs:
- `KSampler` node: change `sampler_name`, `scheduler`, `cfg`, `steps`
- For checkpoints needing CLIP skip 2: add a `CLIPSetLastLayer` node and
rewire `CLIPTextEncode` nodes through it (see
[openwebui-tools/smart_image_gen.py](openwebui-tools/smart_image_gen.py)
for the exact graph).
- For Pony or NoobAI/Illustrious: the required quality-tag prefix
(`score_9, score_8_up, ...` or `masterpiece, best quality, ...`) has
to be typed by the user every time, since the workflow can't inject
it. **For multi-checkpoint deployments, use the smart_image_gen Tool
instead** — it handles per-checkpoint sampler / CFG / steps / CLIP
skip / prefix automatically based on the LLM's `style` choice.

# Image Studio — dedicated image-generation chat model
A custom Open WebUI model preset that wraps a base LLM with a system
prompt heavily biased toward calling the `smart_image_gen` tool. Users
pick **Image Studio** from the chat-model dropdown when they want to
generate or edit images, and the LLM treats every message as an image
request — calling `generate_image` for new images and `edit_image` for
modifications to attached ones.
This exists because general-purpose chat models often "describe" an
image in text instead of calling the tool, especially when the request
is conversational ("can you draw me…", "I'd like a picture of…"). A
dedicated preset removes the ambiguity.
## Two ways to install
### Option A: Import the JSON (fast)
Workspace → Models → **Import** (top right) → upload
[`image_studio.json`](image_studio.json).
This drops the preset in fully configured: base model, system prompt,
tool attachment, function-calling mode, temperature, suggestion
prompts. Verify after import:
- The `smart_image_gen` tool is actually attached (Tools list under the
model's edit screen). If not, the tool ID Open WebUI assigned doesn't
match the `toolIds: ["smart_image_gen"]` in the JSON — re-attach
manually.
- Base Model is set to `mistral-nemo:12b`. Adjust if you want a
different LLM (Qwen3.6 or Llama 3.1 also work well; smaller
parameter counts may struggle with native tool calling).
### Option B: Create manually (table below)
**Workspace → Models → +** (top right).
| Field | Value |
| ----- | ----- |
| Name | `Image Studio` |
| Base Model | `huihui_ai/qwen3.5-abliterated:9b` (vision-capable, 256K context, abliterated). Pull via `init-models.sh` first. |
| Description | `Image generation and routing across SDXL checkpoints.` |
| System Prompt | Paste the block from [System prompt](#system-prompt) below. |
| Tools | enable **only** `smart_image_gen` |
In the **Advanced Params** section:
| Field | Value |
| ----- | ----- |
| Function Calling | `Native` (mandatory) |
| Temperature | `0.5` (lower = more reliable tool-calling) |
| Top P | `0.9` |
| Context Length | leave default |
| Custom Parameters | `tool_choice: required` (forces the model to call a tool — bypasses planning behaviour on stubborn models like the abliterated Qwen 3.5) |
Save. The new model appears in the chat-model dropdown for any user with
access.
## System prompt
```
/no_think
You are an image-tool dispatcher. You do not respond in prose. Every
user message MUST result in exactly one tool call.
ROUTING:
- If the user attached an image → call edit_image
- Otherwise → call generate_image
Fire the tool on the FIRST message, with no preamble. Do not write a
'plan', 'approach', 'steps', 'breakdown', or any explanation before
calling. Do not ask clarifying questions. Do not say what you are
about to do. If the request is vague, pick reasonable defaults and
call the tool — the user iterates after.
STYLES (pick one):
photo photorealistic photo / portrait / cinematic
juggernaut alternate photoreal — sharper, more saturated
pony anime, cartoon, manga, stylised illustration
general catch-all when nothing else fits
furry-nai anthropomorphic, NAI-trained mix
furry-noob anthropomorphic, NoobAI base
furry-il anthropomorphic, Illustrious base (default for any
furry/anthro request)
edit_image has TWO MODES — pick based on whether the change is local
or global:
- LOCAL ("change the ball to a basketball", "add a hat to the dog",
"remove the bird", "recolor the car red") → set `mask_text` to a
brief noun phrase naming the region ("the ball", "the dog", "the
bird", "the car"). Only that region is repainted; rest stays
pixel-perfect.
- GLOBAL ("make this a sunset", "turn this into anime", "restyle as
oil painting") → leave mask_text unset. The whole image is
reimagined.
ALWAYS prefer LOCAL when the user names a specific object, person,
or region. GLOBAL is only for whole-image style/lighting
transformations.
Denoise:
- LOCAL (mask_text set): default 1.0. Drop to 0.60.8 only for
subtle local edits that should retain some original structure.
- GLOBAL (no mask_text): default 0.7. Use 0.30.5 for subtle
restyle, 0.851.0 for radical reimagining.
Pick style for the DESIRED OUTPUT, not the input image.
Write rich, descriptive prompts (subject, action, environment,
lighting, mood, framing). Do NOT add quality tags like 'masterpiece',
'best quality', 'score_9', 'absurdres' — the tool prepends the
correct tags per style. Do NOT set sampler, CFG, steps, scheduler —
the tool picks them.
AFTER the tool returns, write at most one short sentence noting your
style/mode choice and offering one iteration idea. The image is
already shown to the user; do not describe it.
```
The first line `/no_think` disables Qwen 3.x's reasoning phase. If
your base model isn't Qwen 3, leaving it in is a no-op (other models
ignore it). Drop it only if it actually causes problems.
## Vision capability
The shipped preset sets `meta.capabilities.vision: true` so Open WebUI
allows users to attach images to chats with this model. Two paths:
### Default — `huihui_ai/qwen3.5-abliterated:9b`
The shipped preset uses Qwen 3.5 abliterated 9B as the base — vision-
capable, 256K context, no censorship hedging. Preseed via
`init-models.sh` (an `s3_pull` line is already in place; see
[Mirroring models to S3](../README.md#mirroring-models-to-s3) for the
mirror workflow).
**Important Qwen 3.x quirk:** thinking mode is on by default and
breaks native function calling — the model "thinks" about how to use
the tool instead of just calling it. The shipped system prompt starts
with `/no_think` to suppress this. If the model still plans instead
of firing the tool, also set `enable_thinking: false` in **Advanced
Params → Custom Parameters** (API-level enforcement).
### Alternatives
If Qwen 3.5 isn't a fit (size, language preferences, abliteration
caveats), other vision-capable Ollama tags worth trying:
- `qwen2.5vl:7b` — smaller, no thinking mode, very reliable tool-caller
- `llama3.2-vision:11b` — Meta's vision variant, ~7 GB
- `minicpm-v:8b` — fast, capable
To swap, change `base_model_id` in `image_studio.json` (or the Base
Model field if you imported manually) and pull the model via
`init-models.sh` or the Open WebUI model UI.
### Non-vision base model
If you'd rather use a text-only LLM (e.g. `mistral-nemo:12b`),
keep `vision: true` in the preset so Open WebUI still permits image
attachments; the image flows through to `edit_image` via
`__messages__` / `__files__` and ComfyUI does the visual work. The
LLM can't see the image, but for explicit edit instructions ("change
the background to a sunset") that doesn't matter.
## Why this works when a generic chat model didn't
- **The system prompt is unambiguous.** No room for the model to
decide "I'll just describe it in text instead."
- **Only one tool is attached.** No competing tools to choose between.
- **Native function calling is mandatory.** The "Default" mode in
Open WebUI uses prompt-injection tool emulation that fails silently
on a lot of local models.
- **Lower temperature.** Tool calling is more reliable with less
sampling randomness.
## Iterating on the system prompt
If users ask for things you didn't anticipate (specific aspect ratios,
multi-image batches, particular checkpoints not in the routing rules),
edit the system prompt above and re-paste into the Workspace → Models
entry. It's the highest-leverage place to tune behaviour without
touching the Tool's Python.

title: Smart Image Generator & Editor (ComfyUI)
author: ai-stack
version: 0.6.0
description: Generate or edit images via ComfyUI with automatic SDXL
checkpoint routing. Two methods — generate_image (txt2img) and
edit_image (img2img on the user's most recently attached image). The
LLM picks (or auto-detects) the right model — photoreal, Pony
score-tag, NoobAI/Illustrious furry, etc. — and each style ships
with the creator-recommended sampler, scheduler, CFG, steps, CLIP
skip, prompt-prefix dialect, and negatives. The image is uploaded
to Open WebUI's file store and surfaced via a `files` event (the
canonical pattern used by Open WebUI's own image-gen path); the
function return is a short confirmation so the LLM doesn't try to
describe or re-emit the image.

"""
Edit, modify, transform, or restyle an image the user has ATTACHED
to the chat. Use whenever the user uploads an image and asks to
change it. If no image is attached, use generate_image instead.
TWO MODES — choose based on whether the change is local or global:
- LOCAL change ("change the ball to a basketball", "make the dog
wear a hat", "remove the bird") → set `mask_text` to a brief
noun phrase describing the region ("the ball", "the dog", "the
bird"). The tool uses GroundingDINO+SAM to find that region
automatically and only that area is repainted; the rest of the
image stays pixel-perfect.
- GLOBAL change ("make this a sunset", "turn this into anime",
"restyle this as oil painting") → leave `mask_text` unset. The
whole image is reimagined via img2img.
Always prefer LOCAL mode when the user names a specific object,
person, or region. GLOBAL mode is for whole-image style/lighting
transformations.
Denoise tuning:
- LOCAL (mask_text set): default 1.0 — full repaint within mask.
Drop to 0.60.8 for subtle local edits that should retain some
original structure.
- GLOBAL (no mask_text): default 0.7 — moderate edit. Use 0.30.5
for subtle restyling, 0.851.0 for radical reimagining.
Pick `style` for the DESIRED OUTPUT, not the input image.
:param edit_instruction: What the changed area should look like.
Tool auto-prepends quality tags — don't include those.
:param style: One of the StyleName values. Omit to auto-detect.
:param mask_text: Noun phrase describing the region to edit. Set
for LOCAL changes; omit for GLOBAL.
:param denoise: 0.0 = no change, 1.0 = ignore source. Defaults to
1.0 with mask_text, 0.7 without.
:param negative_prompt: Extra terms to exclude. Usually unneeded.
:param seed: 0 to randomize, otherwise specific.
:return: Markdown image of the result, or an error if no image is attached.
