# Kromoss for Draw Things

[Kromoss](https://huggingface.co/lodestones/Kromoss) by lodestones, a full fine-tune of
[MOSS-Image](https://github.com/OpenMOSS/MOSS-Image), converted to [Draw Things](https://drawthings.ai)' model
format. It is a drop-in replacement for Draw Things' MOSS Image SFT: same text encoder, VAE and settings.

| File | Format | Size | SHA-256 |
| --- | --- | --- | --- |
| `kromoss_f16.ckpt` | Full precision (FP16) | 10.2 GB | `5addd66f5b674241987f471b8a8eaddef1404e265eba8521421e135da23ab2ce` |
| `kromoss_q8p.ckpt` | 8-bit | 5.29 GB | `4f2f1a97315ccc9fb95f7f09e39e2f00412b194af258b9326d5046297892cc29` |
| `kromoss_i8x.ckpt` | 8-bit S | 5.14 GB | `56672b6141d51881a93bd2612104b2ae6e7449c891bd19723435ca552b4eb88b` |

You need one of them. 8-bit S has the format of Draw Things' "MOSS Image SFT (8-bit S)" and 8-bit that of
"MOSS Image SFT"; if your Draw Things offers both MOSS variants, either works.

## Install

1. In Draw Things, download **MOSS Image SFT** (any variant) from the model list. That fetches the text encoder
   (`qwen_3.5_9b_i5x.ckpt`) and VAE (`flux_2_vae_f16.ckpt`) Kromoss uses.
2. Put the `.ckpt` you picked in Draw Things' Models folder: the folder you chose in Draw Things' settings, or
   `~/Library/Containers/com.liuliu.draw-things/Data/Documents/Models` by default.
3. Add its entry from this repo's [`custom.json`](custom.json) to `custom.json` in that folder (inside the
   `[ ]`; create the file with `[ ]` around the entry if there is none), then restart Draw Things.

Kromoss then shows in the model list with MOSS's recommended settings.

## Settings

As for MOSS Image SFT: 50 steps, Text Guidance 3, Shift 5, DDIM Trailing (flow-matching Euler, which
lodestones' card recommends).

The 8-step turbo LoRAs in [lodestones/Kromoss](https://huggingface.co/lodestones/Kromoss) are not included.

## Conversion

The weights were converted from `diffusion_models/kromoss_bf16.safetensors` to the tensor layout of Draw
Things' official `moss_image_sft_*.ckpt` files with the Draw Things engine
([draw-things-community](https://github.com/drawthingsai/draw-things-community)). The 8-bit files use the engine's own quantizers with the per-layer
choices of Draw Things' MOSS 8-bit and 8-bit S files. Every converted file has the same 524 tensors as Draw
Things' MOSS Image SFT, each with a cosine similarity of at least 0.97 to it.
