<pre><code># IDK.safetensors — All-in-One Merged LoRA for SDXL

## Description

This is the **IDK LoRA** — a single file that merges all 14 specialized LoRAs from the IDK collection into one convenient package using **hierarchical semantic merging**.

Instead of loading 14 separate LoRAs and balancing their weights, you load one. That's it. One LoRA to rule them all.

**What's inside:**
- Hair: complex hairstyles, extreme length hair, specific bangs, hair dynamics
- Body: ectomorph, mesomorph, hourglass silhouette, pear silhouette
- Style: traditional goth, leather material
- Scene: isolated studio backgrounds, depth of field, macro lens
- General: overall quality enhancement

**The trade-off is simple:** each specialized LoRA will always outperform the merge in its own domain — a dedicated leather LoRA will render leather better than the merge. But the merge gives you **everything at once** without juggling multiple files. It's the "I don't want to think about it" option. Hence the name: **IDK**.

### Before we start...

I spent weeks training 14 specialized LoRAs, carefully tuning each one to perfection.
Then I merged them all into a single file and called it "IDK."

Weeks of work. Summarized in three letters that stand for "I Don't Know."
If that's not a metaphor for the human condition, I don't know what is.
...See? I did it again.

&gt; **Disclaimer:** The dark humor above is just a joke to break the ice and does NOT reflect my actual feelings or beliefs. Just vibes. Enjoy the LoRA!

## What You Get vs. The Specialists

| Feature | IDK (Merged) | Individual LoRAs |
|---|---|---|
| **Convenience** | One file, one weight | 14 files to manage |
| **Quality per concept** | Good | Best |
| **Versatility** | Covers everything | One concept each |
| **VRAM usage** | Single LoRA | Stacks can be heavy |
| **Best for** | Quick generations, exploration | Showcasing specific concepts |

**Bottom line:** Use IDK when you want variety and convenience. Use the specialists when you want maximum quality on a specific concept.

## Trigger Words

Since this is a merge of all 14 LoRAs, you can use trigger words from any of them:

**Hair:**
```
french braids, dreadlocks, space buns, messy bun, twintails, ponytail, drill hair,
floor length hair, rapunzel hair, extremely long hair,
straight bangs, blunt bangs, curtain bangs, hime cut, micro bangs,
floating hair, windblown hair, soaked hair, zero gravity hair
```

**Body:**
```
skinny, slender, prominent collarbone, visible ribs,
athletic, muscular, defined muscle, abs, broad shoulders, toned body,
hourglass figure, narrow waist, wide hips,
pear shaped, bottom heavy, wide pelvis
```

**Style &amp; Material:**
```
trad goth, heavy black makeup, black velvet, black lace, corset, gothic,
leather, matte leather, worn leather jacket, leather texture
```

**Scene &amp; Camera:**
```
simple background, white background, gray background, chroma key,
shallow depth of field, heavy bokeh, cinematic bokeh,
macro shot, extreme close up, eye focus
```

## Recommended Settings

| Setting | Recommended |
|---|---|
| **Base Model** | Any SDXL checkpoint |
| **Sampler** | Euler a, DPM++ SDE Karras, DPM++ 2M Karras |
| **Steps** | 25-35 |
| **CFG Scale** | 5-8 |
| **LoRA Weight** | 0.65 - 0.9 (start at 0.75 — slightly higher than specialists since effects are diluted) |
| **Resolution** | 1024x1024, 896x1152, 832x1216 |
| **VAE** | SDXL default / sdxl-vae-fp16-fix |

## Tips

- Use a **slightly higher weight** (0.75-0.9) compared to the individual LoRAs, since each concept is diluted in the merge.
- **Combine trigger words** from different categories freely — that's the whole point of having everything in one file.
- The merge was done using **hierarchical semantic merging** (not flat averaging), so related concepts reinforce each other instead of canceling out.
- Works with both realistic and stylized SDXL checkpoints.
- If a specific concept isn't strong enough, consider using the dedicated specialist LoRA for that concept instead.
- You can still stack IDK with one or two specialist LoRAs if you want the convenience of the merge plus extra strength on a specific concept.

## How It Was Merged

Not a flat average — that would dilute everything into mush. Instead, the 14 LoRAs were merged in a **semantic tree**:

```
                         IDK (root)
                      /      |      \
                   0.40    0.35    0.25
                   /         |        \
     visual_identity   style_scene   geral
         trunk           trunk
          / \              / \
       0.52 0.48        0.52 0.48
        /     \          /      \
  anatomy   hair    aesthetic  scene
  branch   branch   branch    branch
   (4)      (4)      (2)       (3)
```

LoRAs that share similar concepts (e.g. all hair types together, all body types together) are merged first at the branch level, preserving their shared tensor activations. Branches combine into trunks, and trunks combine into the final root. This **minimizes dilution** and keeps each concept as strong as possible within a single file.

## Prompt for Batch Generation (infinite mode)

Use this prompt with dynamic wildcards `{A|B}` to generate varied showcase images. This prompt intentionally mixes concepts from ALL the specialist LoRAs to demonstrate the merge's versatility.

**Positive:**
