Detail Daemon is a ComfyUI custom node/sampler that controls how much fine detail is added to Flux/SDXL/SD1.5 generations by adjusting the noise schedule during sampling, independent of prompt or model choice. Install via ComfyUI Manager: copy the node's GitHub URL → Manager → "Install from git URL" → restart ComfyUI. Ships with example workflows; the "comparing detailers" workflow is the recommended starting point. The GitHub repo's notes document all sampler settings plus suggested value ranges, which differ by model (Flux vs. SDXL vs. SD1.5).
Detail can be weighted toward the start of generation (bigger, rougher details) or the end (smaller details) via a strength parameter and schedule. Raising strength follows a predictable arc: subtle changes at low values (~0.1, e.g. improved eye/feather detail) → progressively more background detail — notably useful for Flux, which by default produces strong background bokeh with little detail — → overexposure → eventual conversion of the output into a drawing/illustration rather than a photo. Can also fix anatomical issues (e.g. restoring a missing limb) and add texture (fur, glow) before degrading into illustration-like results at the extreme.
