This ComfyUI workflow is a hands-on showcase for six Krea 2 LoRAs, organized into clear groups: Nose Invisibles LoRA, VHS Analog LoRA, RetroAnime LoRA, Commodore 64 Style LoRA, NeonDrip LoRA, and PSX Low Poly LoRA. It lets you run the same prompt through multiple style branches so you can compare looks side-by-side. Outputs are written with SaveImageAdvanced, making it easy to review, sort, and document your best variants.
Technically, each group encapsulates a LoRA application path that adapts your base checkpoint at inference time, with controls for LoRA strength and prompt inputs. The workflow wires shared inputs to each branch so you can keep prompts consistent while varying LoRA weights. Custom nodes (IDs: 33681612-45f1-4901-b3fd-b83f0b48c9c0, 376d014e-b4fd-430e-8201-70629e00857f, 68a3ded7-ee8c-4dc0-8c96-128fdcdd4ef8, 307cc882-db9e-4f8c-93c5-130e09e2c305, fd7b28a7-8ec8-44ef-ad93-dff7afc6086b, 91c1ae42-2e94-4f8e-b10f-25415ac0b64e) bundle the LoRA logic per style group, while SaveImageAdvanced handles filenames, folders, and embedding ComfyUI metadata for reproducibility. This structure is ideal for quick A/B testing of style intensity, prompt phrasing, and seed changes without re-wiring your graph.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
