# MOSS-Image-Base

Quantised media packages of [OpenMOSS-Team/MOSS-Image-Base](https://huggingface.co/OpenMOSS-Team/MOSS-Image-Base).

## MECHA Forge

MECHA — Model Engineering & Contextual Hearth Assembly

These media packages have been forged and optimized in the MECHA Forge.
Each one holds the Denoiser, Text Encoder, and VAE components packaged together for easier deployment.

## Description

MOSS-Image-Base: text-to-image model supporting natural-language prompts, tag sequences, and JSON layouts for controlling text placement and object arrangement. Uses a Qwen3.5 text encoder and the FLUX.2 small VAE decoder.

## Available quantizations

| Quant | Denoiser | Text encoder | VAE |
|---|---|---|---|
| FP4 | FP4 | FP4 | FP8 |
| FP8 | FP8 | FP8 | FP8 |
| INT4 | INT4 | INT4 | INT8 |
| INT8 | INT8 | INT8 | INT8 |

The VAE is shared between formats: FP4 reuses the FP8 file, INT4 reuses the INT8 file.

## Recommended settings

From the source model card (adjust to taste):

| Parameter | Value |
|---|---|
| Steps | 50 |
| CFG / Guidance scale | 3.0 |
| Resolution | 1024 (total pixels) |
| Notes | Flow-matching Euler; shift 5; negative-branch layer skip at 22 |
