# FLUX.1-schnell - Onnx Olive DirectML Optimized 

## Original Model
https://huggingface.co/black-forest-labs/FLUX.1-schnell


## Note on Float16 Conversion:

The Float16 conversion of this model is not yet perfect, and there is a noticeable quality difference compared to the ONNX [Float32](https://huggingface.co/TensorStack/Flux_schnell-f32-onnx) version. While it still produces fantastic images, we are actively working on improving the precision of this model.

We welcome any community assistance or input regarding this conversion.


## C# Inference Demo
https://github.com/TensorStack-AI/OnnxStack

```csharp
// Create Pipeline
var pipeline = FluxPipeline.CreatePipeline("D:\\Models\\Flux_schnell-f32-onnx");

// Prompt
var promptOptions = new PromptOptions
{
    Prompt = "Illustrate a fierce barbarian man, with muscles rippling and wielding a massive axe, roaring in triumph"
};

// Scheduler Options
var schedulerOptions = pipeline.DefaultSchedulerOptions with
{
    GuidanceScale = 0f,
    InferenceSteps = 4,
    SchedulerType = SchedulerType.FlowMatchEulerDiscrete,
};

// Run pipeline
var result = await pipeline.GenerateImageAsync(promptOptions, schedulerOptions);

// Save Image Result
await result.SaveAsync("Result.png");
```
