Kroma v0.2 — Krea 2 fine-tune (full model)

Kroma is a fine-tune of Krea 2. As of v0.2 it is distributed as a full model checkpoint — the v0.1 LoRA-delta packaging has been retired. v0.2 is more training on top of v0.1, with no LoRA delta compression, and the Krea 2 Turbo delta merged in as a rank-512 LoRA — a single file gives you the fine-tuned quality at Turbo speed.

• File: kroma-v0.2-turbo.safetensors (full diffusion model)
• Type: full fine-tuned checkpoint (not a LoRA — no base model required)
• License: MIT

Upgrading from v0.1: v0.1 was a LoRA + .diff deltas loaded on top of a Krea 2 checkpoint. v0.2 replaces that entirely — load it as a normal diffusion model and drop the LoraLoader from your workflow.

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.
