    Flux2 Klein 9b/4b simple workflow (TXT2IMG, IMG2IMG, Edit, metadata export for Civitai) - v1.9
    Preview undefined

    A simple workflow for Klein family models in the first row was developed for 9b and 4b distilled versions, but it should work for base models with minimal changes (such as replacing ConditioningZeroOut with negative conditioning).

    About issues:

    I'm encountering two major problems: Cannot read properties of undefined (reading 'output') and No inner node DTO found for .

    The solution is to launch ComfyUI with the argument --front-end-version Comfy-Org/[email protected] or opposite --front-end-version Comfy-Org/ComfyUI_frontend@latest to get 1.42.5 or newer

    Description

    v.1.8:

    • Some internal remakes, mostly involving the removal of dirty hacks such as any adapters.

    v1.9:

    • Some small mostly visual changes.
