Adds Boogu image support by jtreminio · Pull Request #1419 · mcmonkeyprojects/SwarmUI

jtreminio · 2026-06-17T23:18:54Z

Had to negative match OmniGen due to sharing the same matching headers: https://huggingface.co/Comfy-Org/Omnigen2_ComfyUI_repackaged/blob/main/split_files/diffusion_models/omnigen2_fp16.safetensors

        }
+        else if (IsBoogu() && id is null && (qwenImage = GetPromptImage(true, true)) is not null)
+        {
+            if (!NodeHelpers.TryGetValue("__boogu_edit_cond__", out string booguNode))


this is probably not a good idea

        }
        // TODO: Registry of model default preferences instead of this
-        else if (IsFlux() || IsWanVideo() || IsWanVideo22() || IsOmniGen() || IsQwenImage() || IsZImage() || IsZetaChroma() || IsErnie() || IsHiDreamO1() || IsLens() || IsPixelDiT())
+        else if (IsFlux() || IsWanVideo() || IsWanVideo22() || IsOmniGen() || IsQwenImage() || IsZImage() || IsZetaChroma() || IsErnie() || IsHiDreamO1() || IsLens() || IsPixelDiT() || IsBoogu() )


I had to stare at this for a good 2 minutes before figuring out where the problem was

+        {
+            helpers.LoadClip("boogu", helpers.GetQwen3vl_8bModel());
+            helpers.DoVaeLoader(UserInput.SourceSession?.User?.Settings?.VAEs?.DefaultFluxVAE, "flux-1", "flux-ae");
+            double shift = UserInput.Get(T2IParamTypes.SigmaShift, 3, sectionId: sectionId);


are you sure this model needs a custom default shift?

Going off of [implementation PR](https://github.com/Comfy-Org/ComfyUI/pull/14523), can maybe just scale it back to only apply on edit?

It's already defaulted to 3.16, I don't see why you would custom-default to 3 instead of 3.16?

+            {
+                double shift = UserInput.Get(T2IParamTypes.SigmaShift, 3.16, sectionId: sectionId);


I'm still wondering why the custom default sigma shift

Removed. I missed that it's baked into ComfyUI. I don't know why it was in the printed workflow then.

presumably to suggest users try modifying it, ie for Swarm side it should be on the AuraFlow modifiable sigma shift list

Added back in, user overrideable

the No here doesn't sound correct to what was said on discord

... Also I kinda doubt MLLM is correct

It's uncensored in my tests, has poor knowledge of genitals but doesn't shy away from it.

Then "Minimal" means it's eg missing genitals but otherwise complete,

+- Uses the Flux.1 VAE and a Qwen3-VL text encoder, both downloaded and handled automatically.
+- For editing, use the `Edit` model and give it an init image - SwarmUI automatically wires it in as the reference.


init image is strange

        AddStep(g =>
        {
-            g.FinalPrompt = g.CreateConditioning(g.UserInput.Get(T2IParamTypes.Prompt), g.CurrentTextEnc.Path, g.UserInput.Get(T2IParamTypes.Model), true, "6");
+            if (g.IsBooguEdit())


wrong place to impl this

+    public bool IsBooguEdit() => IsBoogu() && UserInput.TryGet(T2IParamTypes.PromptImages, out List<Image> images) && images.Count > 0;


This one I waffled on, ended up adding. Since the predicate is different than others in this file, let me know if you prefer to remove it.

mcmonkey4eva · 2026-06-20T22:41:23Z

    /// <summary>Creates a "CLIPTextEncode" or equivalent node for the given input, applying prompt-given conditioning modifiers as relevant.</summary>

    {
+        if (IsBooguEdit() && isPositive)


Wrong place for this, put it where the code for other model-specific stuff is. And make sure swarmtextencodeadvanced works when it's supposed to

+- **Parameters:**
+    - **Sampler**: For Turbo, use LCM, otherwise DPM++ 2M is fine.


There is Base, Edit, Turbo. They are different models with different defaults and potentially different recommendations, this should be clarified here.

The custom-default unmodified shift is weird and shouldn't be here
