The LTXVScheduler node generates sigma values for custom sampling processes. It calculates noise schedule parameters based on the number of tokens in the input latent and applies a sigmoid transformation to create the sampling schedule. The node can optionally stretch the resulting sigmas to match a specified terminal value.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `steps` | Number of sampling steps (default: 20) | INT | Yes | 1-10000 |
| `max_shift` | Maximum shift value for sigma calculation (default: 2.05) | FLOAT | Yes | 0.0-100.0 |
| `base_shift` | Base shift value for sigma calculation (default: 0.95) | FLOAT | Yes | 0.0-100.0 |
| `stretch` | Stretch the sigmas to be in the range [terminal, 1] (default: True) | BOOLEAN | Yes | True/False |
| `terminal` | The terminal value of the sigmas after stretching (default: 0.1) | FLOAT | Yes | 0.0-0.99 |
| `latent` | Optional latent input used to calculate token count for sigma adjustment | LATENT | No | - |

**Note:** The `latent` parameter is optional. When not provided, the node uses a default token count of 4096 for calculations.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `sigmas` | Generated sigma values for the sampling process | SIGMAS |
