❌ Load TinyBreaker Checkpoint [Deprecated]

Every now and then you load a workflow and hit a ❌ Load TinyBreaker Checkpoint [Deprecated] node, and the first question is "did I install the wrong thing?" You didn't. This is just the pack's original checkpoint loader - the one from before the model got its CLIP output, its upscaler VAE, and its metadata output. The pack renamed the modern version (now 💪TB | Load TinyBreaker Checkpoint, note the "Ckpt"), and the old class was parked under __deprecated so saved workflows still load instead of erroring out.

What it did

Back in the early days, a TinyBreaker checkpoint was loaded as a simpler bundle: MODEL, VAE, TRANSCODER, REFINER_MODEL, REFINER_CLIP, and GENPARAMS (the settings from the checkpoint's metadata). The inputs were just ckpt_name and a vae choice of fast vs high quality. That's the whole surface - no separate upscaler VAE, no dedicated CLIP output for the base stage, and no upscaler_vae_type dropdown. It's recognizably the same loader, just a leaner, older skeleton.

Why it's gone

The modern loader's eight outputs (adding CLIP and UPSCALER_VAE) reflect how the model grew: the tiny upscaler needs its own VAE, and the base stage's text encoder deserves its own output rather than being folded into the bundle. The "fast vs high quality" split also became a three-way auto/fast/high_quality choice, applied separately for generation and upscaling. In other words, the deprecated node isn't wrong, it's just shaped for a checkpoint the pack no longer ships workflows for.

If you're stuck with it

Your options are the same for every deprecated node: right-click → replace with the current 💪TB | Load TinyBreaker Checkpoint and rewire the outputs that changed (the modern one's CLIP and UPSCALER_VAE outputs just get ignored or hooked up if your graph uses them), or drag the pack's reference workflow image into ComfyUI and start from a clean, current graph. Old workflows that still work on old checkpoints can keep limping along - but the deprecated loader may not know about the prototype1-era components, so if the upscaler or metadata silently misbehave, that's the reason.

Install

It ships inside the pack, so any install covers it: ComfyUI Manager search "tinybreaker", or git clone https://github.com/martin-rizzo/ComfyUI-TinyBreaker into custom_nodes, restart. Deprecated nodes are hidden from the default menu, so if you're hunting for it deliberately you're already going the wrong way - the current loader (and its advanced variant with per-component overrides) is what you actually want. Port the workflow forward; it's a ten-minute job and the modern loader is strictly more capable.
