ComfyUI-CapitanFlowMatch is a custom node set for ComfyUI that provides samplers and scheduling presets designed specifically for rectified flow / flow-matching models such as Flux, SD3, and Z-Image. These nodes are built to match how flow models behave internally, instead of relying on diffusion-era assumptions.Read the repo for more in-depth details: <a target="_blank" rel="ugc" href="https://github.com/capitan01R/ComfyUI-CapitanFlowMatch">https://github.com/capitan01R/ComfyUI-CapitanFlowMatch</a>What it includes<ul><li>Model-specific preset nodes that output recommended steps, sigmas, and schedule shift values for major flow models</li><li>Manual control nodes for adjusting step count and schedule shift</li><li>Three custom samplers:<ul><li><code>capitan_flowmatch</code> – balanced, general-purpose flow sampler (z-image turbo sweet spot 2.00 cfg and 36 steps) maximum adherence<span style="background-color:rgb(18, 18, 19);color:rgb(193, 194, 196);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, &quot;Helvetica Neue&quot;, Arial, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot;, sans-serif;font-size:14px">.</li><li><code>capitan_flowmatch_advanced</code> – smoother behavior at higher step counts</li><li><code>capitan_flowmatch_turbo</code> – tuned for fast and distilled flow models</li></ul></li><li>Compatible with <code>SamplerCustom</code> / <code>KSampler</code> workflows in ComfyUI</li></ul>Why it existsMost existing samplers and schedules were designed around diffusion models and don’t translate cleanly to flow-matching. This can lead to instability, loss of detail, or degraded results at higher steps. CapitanFlowMatch provides samplers and presets that align with flow-model dynamics to improve consistency and output quality.InstallationInstall via ComfyUI Manager by searching for <code>ComfyUI-CapitanFlowMatch</code>, or clone the repository into <code>ComfyUI/custom_nodes</code> and restart ComfyUI.Repo: <a target="_blank" rel="ugc" href="https://github.com/capitan01R/ComfyUI-CapitanFlowMatch">https://github.com/capitan01R/ComfyUI-CapitanFlowMatch</a><a target="_blank" rel="ugc" href="https://pastebin.com/wBTZa731">Workflow</a><span style="background-color:rgb(18, 18, 19);color:rgb(193, 194, 196);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, &quot;Helvetica Neue&quot;, Arial, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot;, sans-serif;font-size:14px">resource used in workflow aside from the samplers (this is used for max prompt following and adherence)<span style="background-color:rgb(18, 18, 19);color:rgb(193, 194, 196);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, &quot;Helvetica Neue&quot;, Arial, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;, &quot;Segoe UI Symbol&quot;, sans-serif;font-size:14px">: <a target="_blank" rel="ugc" href="https://github.com/capitan01R/Capitan-ConditioningEnhancer">https://github.com/capitan01R/Capitan-ConditioningEnhancer</a>
