Learn its inputs, outputs, parameters and usage. The SamplerDPMPP\_3M\_SDE node creates a DPM++ 3M SDE sampler for use in the sampling process. This sampler uses a third-order multistep stochastic differential equation method with configurable noise parameters. The node allows you to choose whether noise calculations are performed on the GPU or CPU. ## Inputs | Parameter | Description | Data Type | Required | Range | | -------------- | ----------------------------------------------------------------------------- | --------- | -------- | ---------------- | | `eta` | Controls the stochasticity of the sampling process (default: 1.0) | FLOAT | Yes | 0.0 - 100.0 | | `s_noise` | Controls the amount of noise added during sampling (default: 1.0) | FLOAT | Yes | 0.0 - 100.0 | | `noise_device` | Selects the device for noise calculations, either GPU or CPU (default: "gpu") | COMBO | Yes | "gpu"
"cpu" | ## Outputs | Output Name | Description | Data Type | | ----------- | ----------------------------------------------------------------- | --------- | | `sampler` | Returns a configured sampler object for use in sampling workflows | SAMPLER | > This documentation was AI-generated.
