# Flux2Scheduler - ComfyUI Built-in Node Documentation

> Flux2Scheduler generates a sequence of noise levels (sigmas) for the denoising process, specifically tailored for the Flux model.

Flux2Scheduler generates a sequence of noise levels (sigmas) for the denoising process, specifically tailored for the Flux model. It calculates a schedule based on the number of denoising steps and the dimensions of the target image, which influences the progression of noise removal during image generation.

## Inputs

| Parameter | Description                                                                                                                                  | Data Type | Required | Range       |
| --------- | -------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------- |
| `steps`   | The number of denoising steps to perform. A higher value typically leads to more detailed results but takes longer to process (default: 20). | INT       | Yes      | 1 to 4096   |
| `width`   | The width of the image to be generated, in pixels. This value influences the noise schedule calculation (default: 1024).                     | INT       | Yes      | 16 to 16384 |
| `height`  | The height of the image to be generated, in pixels. This value influences the noise schedule calculation (default: 1024).                    | INT       | Yes      | 16 to 16384 |

Note: The schedule is computed from the image sequence length, which is derived from `width` and `height` as `(width * height) / 256`, reflecting the model's 16x latent downsampling. Larger images produce longer sequences, which shifts the noise schedule accordingly.

## Outputs

| Output Name | Description                                                                                   | Data Type |
| ----------- | --------------------------------------------------------------------------------------------- | --------- |
| `sigmas`    | A sequence of noise level values (sigmas) that define the denoising schedule for the sampler. | SIGMAS    |
