    If SaveConditioning is the pack's write half, LoadConditioning is the read half - and it's the one you'll actually want sitting in your workflow day to day. It reads a .cond file (a saved CONDITIONING from the companion SaveConditioning node) and outputs the exact same tensors, so you can run generations without paying for a CLIP encode. Same prompt across a batch of images, or the same prompt in a workflow you rebuild constantly? This is how you stop re-encoding it.

    The mechanism is straightforward. On load it picks a .cond from input/conditioning/ - the folder is auto-created on first use - and hands it to torch.load() with map_location="cpu", then returns the conditioning. Two implementation details shape how the node behaves:

    • It tracks the file, not just the name. The node SHA-256 hashes the file contents, so if you drop in a new .cond with the same name, ComfyUI notices and re-runs everything downstream. No stale-cache surprises when you update the file.
    • It validates before running. If the selected file has vanished, you get an "Invalid conditioning file" message instead of a mid-graph crash.

    Inputs and outputs are a short list: one input, one output.

    • conditioning_file - a dropdown listing every .cond file in input/conditioning/. It's populated when the node is created, so a freshly saved file needs a workflow refresh (or re-adding the node) to show up.
    • CONDITIONING - the loaded tensors, ready to plug into KSampler's positive or negative, or any other CONDITIONING input on the graph.

    Install is the same as its sibling - same pack, after all. In ComfyUI Manager, search "ComfyUI Conditioning Saver", or:

    cd ComfyUI/custom_nodes
    git clone https://github.com/nicehero/comfyui-conditioning-saver
    

    then restart. Nothing to download, torch is the only dependency, MIT-licensed.

    Where people get burned - the honest list:

    • The file lives in input/conditioning/. SaveConditioning writes to output/conditioning/, so the README's flow has you move the file between the two folders. If your dropdown is empty, that's the first thing to check.
    • The dropdown is a snapshot. Files added after the node already exists won't appear until the workflow refreshes.
    • Trust and compatibility. This node loads with weights_only=False, which means it will happily unpickle arbitrary data - only load .cond files you created yourself. And the tensors are model-specific: a conditioning encoded for SDXL won't behave in a Flux graph. It's a cache, not a universal prompt format.

    The use case here is real - people reach for conditioning-caching nodes precisely for the repetitive-prompt batch work this pack targets, and this pair is a clean, dependency-free way to do it. Load your saved conditioning and let the text encoder sit this one out.
