# Nitro-E 1024px - Diffusers Integration

This is the Nitro-E 1024px text-to-image diffusion model in diffusers format.

## Model Description

Nitro-E is a family of text-to-image diffusion models focused on highly efficient training. With just 304M parameters, Nitro-E is designed to be resource-friendly for both training and inference.

**Key Features:**
- 304M parameters
- Efficient training: 1.5 days on 8x AMD Instinct MI300X GPUs
- High throughput: Optimized samples/second on single MI300X
- Consumer GPU support: Fast per 1024px image on Strix Halo iGPU

## Model Variant

This is the **1024px** variant, optimized for generating 1024x1024 images.

**Note**: This variant uses standard attention (no ASA subsampling).

## Original Model

This model is based on [amd/Nitro-E](https://huggingface.co/amd/Nitro-E) and has been converted to the diffusers format for easier integration and use.

## Usage

```python
import torch
from diffusers import NitroEPipeline

# Load pipeline
pipe = NitroEPipeline.from_pretrained("blanchon/nitro_e_1024", torch_dtype=torch.bfloat16)
pipe = pipe.to("cuda")

# Generate 1024x1024 image
prompt = "A hot air balloon in the shape of a heart grand canyon"
image = pipe(
    prompt=prompt,
    width=1024,
    height=1024,
    num_inference_steps=20,
    guidance_scale=4.5,
).images[0]

image.save("output.png")
```

## Technical Details
