☁️BizyAir DisableNoise

SamplerCustomAdvanced-style pipelines split "how much noise do we start from" into its own node so you can choose deliberately instead of always getting a fresh random seed's worth. DisableNoise hands back a NOISE object that adds nothing - useful whenever you want the sampler to work purely from the latent you already have (a partially-denoised latent carried over from an earlier pass, or a straight continuation) instead of layering new random noise on top of it.

How it works

No inputs, one output. Plug it into the noise slot of an advanced sampler node in place of a normal random-noise generator, and that pass runs without injecting anything extra. It's the kind of small, single-purpose node that's easy to overlook and genuinely necessary once your workflow needs precise control over exactly where noise enters the pipeline - chained samplers, latent blending, multi-stage refinement.

The inputs and outputs that matter

• No required or optional inputs.
• Output: NOISE - wire it into an advanced sampler's noise input.

How to install it

ComfyUI Manager: search BizyAir, install, restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAir

then restart. BizyAir wants an account and API key configured from first use per the README.

One thing worth knowing before you install anything named BizyAir at all: several users have reported it appearing in their custom_nodes folder unprompted - installed automatically by ComfyUI Manager's missing-node resolver when loading older workflows (pre-February 2025) that referenced a generic node name Manager guessed wrong on, a bug the Manager maintainer has since acknowledged and fixed going forward. People who hit this reported real follow-on friction - workflows stalling partway through, or files turning up in their Python virtualenv after just deleting the custom_nodes folder by hand. If you didn't intend to install the pack, uninstall it through Manager itself (not a manual folder delete) so its dependencies get cleaned up too, rather than fighting stray files afterward.

Common issues & troubleshooting

Sampler still adds noise anyway. Confirm you actually wired this into the noise slot and not the latent slot - the two are easy to mix up on SamplerCustomAdvanced-style nodes, and only one of them is what this output is for.

You didn't mean to install BizyAir at all. See the install note above - this is the most likely node in the pack to have arrived via a Manager auto-resolve on an old workflow rather than a deliberate choice, since its name and purpose overlap with a very generic-sounding core ComfyUI concept.
