# MiniT2I Diffusers Checkpoints

This private repository contains the Diffusers-compatible PyTorch weights for both MiniT2I-B/16 and MiniT2I-L/16. MiniT2I-B/16 uses the JAX checkpoint EMA decay `0.99995`, and MiniT2I-L/16 uses EMA decay `0.9999`; both are exported from step 290K. Load one repository, then select the model at inference time with `model_type`.

## Models

| `model_type` | Model | Directory |
| --- | --- | --- |
| `b16` | MiniT2I-B/16 | `minit2i-b-16/` |
| `l16` | MiniT2I-L/16 | `minit2i-l-16/` |

Aliases such as `b`, `base`, `minit2i-b/16`, `l`, `large`, and `minit2i-l/16` are also supported.

## Usage

```python
import torch
from diffusers import DiffusionPipeline

HUB_MODEL_ID = "MiniT2I/MiniT2I"

pipe = DiffusionPipeline.from_pretrained(
    HUB_MODEL_ID,
    custom_pipeline=HUB_MODEL_ID,
    trust_remote_code=True,
)

image = pipe(
    "A lonely astronaut standing on a quiet beach under two moons.",
    model_type="b16",
    guidance_scale=2.5,
    num_inference_steps=100,
    torch_dtype=torch.bfloat16,
).images[0]
image.save("minit2i-b16.png")

image = pipe(
    "a watercolor painting of a mountain lake at sunrise",
    model_type="l16",
    guidance_scale=6.0,
    num_inference_steps=100,
    torch_dtype=torch.bfloat16,
).images[0]
image.save("minit2i-l16.png")
```

The selected submodel is downloaded lazily from this repository, so calling with `model_type="b16"` does not download the L/16 weights.
