| # Kroma v0.2 — Krea 2 fine-tune (full model, **quantized to ComfyUI formats**) |
|
|
| **[Kroma](https://huggingface.co/lodestones/Kroma)** is a fine-tune of **Krea 2** by Lodestone-Rock. This repo contains quantized .safetensors files in various ComfyUI formats of the Kroma model. |
|
|
| --- |
|
|
| ## Running in ComfyUI |
|
|
| ### 1. Requirements |
| - A recent **ComfyUI** with native **Krea 2** support (update to the latest master). |
| - The **Krea 2** text encoder and VAE (the diffusion model is this repo — no separate |
| base checkpoint needed). |
|
|
| ### 2. Files to download |
| Place these in your ComfyUI folders: |
|
|
| | What | Where | Notes | |
| |------|-------|-------| |
| | `kroma-v0.2-turbo.safetensors` | `ComfyUI/models/diffusion_models/` | this repo | |
| | Krea 2 text encoder (Qwen3-VL) | `ComfyUI/models/text_encoders/` | load with CLIPLoader type `krea2` | |
| | Krea 2 VAE | `ComfyUI/models/vae/` | | |
|
|
| ### 3. Sampling settings |
| The Krea 2 Turbo delta is merged in, so sample with **Turbo settings**: |
|
|
| | Setting | Value | |
| |---------|-------| |
| | Steps | **8-12** | |
| | Guidance (CFG) | **1.0 – 1.5** | |
| | Shift (mu) | **1.15** | |
|
|
| > These are the settings the Turbo checkpoint was distilled for; keep them for best |
| > results. |
|
|
| ### 4. Workflow |
| 1. **Load Diffusion Model** → select `kroma-v0.2-turbo.safetensors`. |
| 2. **Load CLIP** → the Krea 2 text encoder, set type to **`krea2`**. |
| 3. **Load VAE** → the Krea 2 VAE. |
| 4. **KSampler** → steps / CFG / shift per the table above. |
| 5. Prompt and generate. |
|
|
| **Minimal node chain:** |
| ``` |
| Load Diffusion Model (kroma-v0.2) ─► KSampler ─► VAE Decode ─► Save Image |
| Load CLIP (krea2) ─────────────────► (clip) ▲ |
| Load VAE ───────────────────────────────────────┘ |
| Empty Latent / prompt ────────────────────────────► |
| ``` |
|
|
| ### 5. Tips |
| - If the output looks off, confirm the text encoder is loaded with type **`krea2`** |
| (Krea 2 expects a 12-layer Qwen3-VL stack) and that you're on a current ComfyUI. |

|
| ## Provenance |
| v0.2 was produced by continued full fine-tuning of the K2 (Krea 2) checkpoint behind |
| Kroma v0.1 — without the rank-256 LoRA delta compression used for the v0.1 release — |
| followed by merging the **Krea 2 Turbo delta** in as a **rank-512 LoRA**. |

| fine-tune does not grant any rights to the base weights. |
