Run your AI Toolkit-trained FLUX.1 Dev LoRA in ComfyUI with training-matched behavior using a single RCFluxDev custom node.Who it's for: creators who want this pipeline in ComfyUI without assembling nodes from scratch. Not for: one-click results with zero tuning — you still choose inputs, prompts, and settings.<h3 id="open-preloaded-workflow-on-runcomfy">Open preloaded workflow on RunComfy</h3><a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/flux1-dev-ai-toolkit-lora-inference-in-comfyui-training-matched-results?utm_source=civitai&amp;utm_medium=referral">Open preloaded workflow on RunComfy (browser)</a>Why RunComfy first - Fewer missing-node surprises — run the graph in a managed environment before you mirror it locally. - Quick GPU tryout — useful if your local VRAM or install time is the bottleneck. - Matches the published JSON — the zip follows the same runnable workflow you can open on RunComfy.When downloading for local ComfyUI makes sense — you want full control over models on disk, batch scripting, or offline runs.How to use (local ComfyUI) 1. Load inputs (images/video/audio) in the marked loader nodes. 2. Set prompts, resolution, and seeds; start with a short test run. 3. Export from the Save / Write nodes shown in the graph.Expectations — First run may pull large weights; cloud runs may require a free RunComfy account.<hr /><h3 id="overview">Overview</h3>FLUX.1 Dev LoRA Inference is a ComfyUI workflow built for running AI Toolkit-trained FLUX.1 Dev LoRAs with minimal preview drift. Instead of wiring a generic FLUX sampler graph, it uses the RC FLUX.1 Dev custom node to route generation through a model-specific inference pipeline aligned with AI Toolkit preview sampling. This approach stabilizes results with FLUX.1 Dev-correct defaults and repeatable sampling across runs.Important nodes:<ul><li>RC FLUX.1 Dev (RCFluxDev)</li><li>SaveImage</li></ul><h3 id="notes">Notes</h3>FLUX.1 Dev LoRA Inference in ComfyUI | RunComfy Workflow (Training-Matched Results) — see <a target="_blank" rel="ugc" href="https://www.runcomfy.com/comfyui-workflows/flux1-dev-ai-toolkit-lora-inference-in-comfyui-training-matched-results?utm_source=civitai&amp;utm_medium=referral">RunComfy page</a> for the latest node requirements.
