⚗️🔬| Z-Sampler Turbo ^G2.1
Experimental new version of Z-Sampler Turbo. It takes a Z-Image Turbo model, an initial latent image, and prompt/conditioning to produce a denoised latent output, which can then be decoded into the final image. ⚠️ Because this node is experimental, its parameters, behavior, or availability may change or be removed entirely without prior notice.

Inputs (14)
| Name | Type | Default | Description |
|---|---|---|---|
| latent_input | LATENT | The initial latent image to be denoised; usually an 'Empty Latent' for text-to-image tasks or an encoded image for image-to-image processing. | |
| model | MODEL | The Z-Image Turbo model used for denoising the latent image. | |
| positive | CONDITIONING | The main prompt/conditioning used to guide the generation process toward the desired content. | |
| seed | INT | 11–18446744073709550000 | The seed used for the random noise generator, ensuring the same result is produced with the same value. |
| divider1 | ZIPN_SEPARATOR | — | |
| steps | INT | 82–14 | Number of iterations to perform during the denoising process. |
| initial_bias | FLOAT | 0.0-0.5–0.5 | Custom adjustment for initial noise bias, usually kept at 0.0; Positive values amplify dominant prompt features (e.g., making bright scenes brighter or dark scenes darker), while negative values temper them. Keep in mind it reacts differently to every prompt, it's not a simple brightness control. |
| latent_scaling | COMBO | Determines the resolution scale applied to latents during each sampling stage. 'Max Speed' uses lower internal scaling for faster generation, while 'Max Quality' employs higher scaling to preserve finer details and structural integrity at the cost of processing time. | |
| spectral_tilt | COMBO | Applies a frequency-based bias to the noise across sampling stages. Early stages amplify low-frequency noise to establish composition, while later stages shift focus to high-frequency components to sharpen fine details. Each preset defines which stages (1, 2, or 3) receive this spectral modification and the intensity of the adjustment. | |
| turbo_creativity | BOOLEAN | false | Enables turbo creativity. This scrambles the image to boost diversity in compositions while maintaining the general style and tone color. Be aware that this may lead to hallucinations. |
| detailed_refiner | BOOLEAN | true | Enables an alternative refiner using the DPM++ SDE sampler during the final stage. This enhances contrast and sharpness in fine details but increases overall processing time. |
| new_scheduler | BOOLEAN | true | Enables the optimized scheduler with an updated set of sigmas for superior general quality. Disabling this switches back to the legacy version, which may still perform better in specific edge cases. |
| positive_stg2opt | CONDITIONING | This input is optional and can remain disconnected. It allows specifying a different prompt/conditioning for the second stage of the denoising process. | |
| positive_stg3opt | CONDITIONING | This input is optional and can remain disconnected. It allows specifying a different prompt/conditioning for the third stage of the denoising process. |
