☁️BizyAir Detail Daemon Sampler

Same trick as BizyAir Detail Daemon Graph Sigmas - a sigma-schedule adjustment that adds perceived detail to Flux, HiDream, and pretty much anything else without touching CFG or step count - but wired as a sampler wrapper instead of a graph-sigmas patch. If your workflow is built around SamplerCustomAdvanced, this is the variant that actually fits: it takes a SAMPLER in, hands you a modified SAMPLER back out.

How it works

The node's own description says it plainly: "This sampler wrapper works by adjusting the sigma passed to the model, while the rest of sampling stays the same." At each step, in the window you define, it nudges the sigma the model sees slightly lower than reality - the model reads that as "less noise left than there is" and adds finer texture in response. It's the same mechanism as the Graph Sigmas version, just applied by wrapping whatever sampler you're already using rather than mutating the sigma tensor directly.

Real-world usage from the community: people chain it with sigma manipulation for extra effect - "I've added the detail daemon sampler and lying sigma in succession and used plugged a custom scheduler into the sigma node for the CustomSamplerAdvanced," as one user described their high-contrast Flux/HiDream setup. And the headline result people report is specifically Flux's skin texture: "Detail daemon also takes Flux to another level. Specially the plastic skin."

The inputs and outputs that matter

• sampler (SAMPLER) - the sampler object to wrap, straight from a KSamplerSelect-style node.
• detail_amount (default 0.1), start/end (0.2/0.8), bias (0.5), exponent, start_offset, end_offset, fade, smooth - identical parameters and defaults to the Graph Sigmas variant; see that article if you want the full breakdown of what each one shapes.
• cfg_scale_override (default 0) - the one input that differs from the Graph Sigmas node. The tooltip is the author's own explanation: "If set to 0, the sampler will automatically determine the CFG scale (if possible). Set to some other value to override." Leave it at 0 unless auto-detection is giving you a visibly wrong result.

Output: a single SAMPLER - wire it into the sampler input of SamplerCustomAdvanced in place of whatever you were using before.

How to install it

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

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

then restart. Per the README, BizyAir expects an account and API key set up on first use - the pack is a cloud-relay product end to end, so log in even for a node that's really just local sigma math.

Common issues & troubleshooting

Detail turns into invented elements. Same failure mode as the Graph Sigmas variant - detail_amount past roughly 0.3-0.5 starts adding things the prompt didn't ask for rather than sharpening what's there. Dial it back.

cfg_scale_override picking a value you don't want. Set it explicitly to your actual CFG/guidance instead of relying on auto-detect, especially on guidance-distilled models like Flux where "CFG" isn't a literal sampler setting.

Not sure which Detail Daemon node to use. If your graph passes SIGMAS tensors directly (custom scheduler chains, manual sigma manipulation), use BizyAir Detail Daemon Graph Sigmas instead - this one is specifically for the SamplerCustomAdvanced pattern.
