Turn a text prompt into a sharp, detailed image
Open this ready-to-run workflow on Floyo. No install needed.
HOW IT WORKS
Step 1. Write your prompt Describe the image, the style, the lighting, and the composition. Klein 9B follows detailed prompts well, so the more specific you are, the closer the result. Works great with: photorealism · detailed scenes · concept art · product shots
Step 2. Set a negative prompt (optional) List what to keep out of the image, like "blurry, bad quality," to clean up the result.
Step 3. Hit run and download You get back a 1024px image in a few steps. Preview it in the workflow, then download. Ready for: Photoshop · Figma · Canva · any editor
First time? Leave every setting as-is. The defaults (1024 x 1024 · 20 steps · CFG 5) are the right starting point for almost everyone.
Overview
This workflow generates an image from a text prompt using FLUX.2 Klein 9B, an open-weight model from Black Forest Labs. Klein 9B is the 9-billion parameter model in the FLUX.2 family, built for sharp detail and close prompt following. It reads your prompt through a Qwen3 text encoder, so long, specific descriptions land better than short keyword lists. You type a prompt, hit run, and get back a 1024px image in about 17 seconds. No input image, no setup, no nodes to wire.
Who it's for: creators who want FLUX.2 Klein 9B running in ComfyUI without setting up the model and nodes from scratch. Not for: one-click results with zero tuning. You still write the prompt, and you choose the settings.
Why Floyo
Floyo is the only ComfyUI platform built for teams in the browser.
Made for teams. Share run history, files, and models across your whole team. A teammate opens your exact run and picks up where you left off. No file handoffs, no version confusion.
No install, no setup. Every workflow and model is preloaded. Open it in your browser and run. Nothing to download, nothing to configure.
No local hardware. Workflows run on H100 NVL GPUs, so heavy models run fast without a card of your own. Your VRAM stops being the limit.
Open and closed models in one place. Floyo runs open-source workflows and API models side by side.
How to use (in your browser on Floyo)
Write a prompt. Name the subject, the lighting, and the composition. The more specific you are, the closer the result.
Add a negative prompt if you want, then run with the defaults (1024 x 1024, 20 steps, CFG 5).
Download the image from the run, ready for any editor.
Expectations
The models are preloaded, so there is nothing to download. Running it needs a free Floyo account. Each image comes back in about 17 seconds, so iterating on prompts stays quick. One limit to know: this model does not render in-image text reliably, so use it for visuals, not typography.

Concept & Art. Produce concept art and a range of styles, not only photoreal.
Product & Marketing. Make clean product shots and design references with strong detail.
