I think no one are insane enough to train models / LoRAs with different objective.

AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

  • This workflow is for comparing `zero uncond` with `null uncond` on a current vpred model; its named components indicate text and latent inputs, sampling, VAE decoding, and saved image outputs.

    Suggestion · not verified

Flow

  • The workflow lists checkpoint loading, text encoding, conditioning adjustments, scheduling, sampling, VAE decoding, and image saving; connections between these stages are not specified.

Inputs and outputs

  • The named `EmptyLatentImage` and `CLIPTextEncode` indicate latent and text-conditioning inputs, while `VAEDecode` and `SaveImage` indicate decoded images saved as outputs.

    Suggestion · not verified

Setup

  • It is listed as a `Workflows` item using the `Illustrious` base model and published by `6DammK9`.

Dependencies

  • Before use, verify that these named items are available: `KSampler`, `VAEDecode`, `ConditioningZeroOut`, `ConditioningAverage`, `CheckpointLoaderSimple`, `SamplerCustom`, and `CLIPSetLastLayer`.

    Suggestion · not verified

  • Also verify `KSamplerSelect`, `SaveImage`, `EmptyLatentImage`, `CLIPTextEncode`, `BasicScheduler`, `ModelSamplingDiscrete`, and `at-step00394590.safetensors`.

    Suggestion · not verified

Configuration

  • The described use case involves switching a finetuned model’s objective, such as from `eps` to `vpred` or from `vpred` to `RF`.

Cautions

  • The description warns that a math special case can cause drastic differences between WebUIs and ComfyUI.

  • The listing does not specify a usage license, so verify reuse terms before using it.
