# Meisho-S1-Preview
A Meisho S1 Preview is a generalist image-generation model based on [Tongyi-MAI/Z-Image](https://huggingface.co/Tongyi-MAI/Z-Image), finetuned on our [LucidityAI/meisho-sft dataset](https://huggingface.co/LucidityAI/meisho-sft)
Compared to it's base model, Meisho-S1-Preview handles areas like typography better, while having regressions in other places (see limitations), which we aim to resolve and surpass the base-model at in a later version, whether it be in a second version of a preview or the final S1 version, among the possibility of splitting Meisho into flash and pro versions, like our Synth 2.5 family.
## Usage
You may use Meisho S1 Preview like so:
```python
import torch
from diffsynth.pipelines.z_image import ZImagePipeline, ModelConfig
pipe = ZImagePipeline.from_pretrained(
torch_dtype=torch.bfloat16,
device="cuda",
model_configs=[
ModelConfig(path=["<repo>/transformer/diffusion_pytorch_model-00001-of-00002.safetensors",
"<repo>/transformer/diffusion_pytorch_model-00002-of-00002.safetensors"]),
ModelConfig(path=["<repo>/text_encoder/model-0000{}-of-00003.safetensors".format(i) for i in (1,2,3)]),
ModelConfig(path="<repo>/vae/diffusion_pytorch_model.safetensors"),
],
tokenizer_config=ModelConfig(path="LucidityAI/Meisho-S1-Preview/tokenizer"),
)
image = pipe(
prompt="...",
seed=1234, rand_device="cuda",
num_inference_steps=50, cfg_scale=4.0,
height=1024, width=1024,
)
```
Recommended settings: `num_inference_steps=50`, `cfg_scale=4.0`, 1024×1024. This is a
non-distilled base model, so it needs the full step count, unlike Z-Image-Turbo.

## Limitations
The preview version of Meisho-S1 struggles with:
- Detail
- Clothing
- Photorealistic people
