HiDream O1 Image ComfyUI Image Editing | Precision Reference Edit Workflow

Edit photos smartly while keeping the original style intact.

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.

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.

Overview

This workflow empowers you to refine portraits, products, and interiors through prompt-guided image modifications that keep composition intact. It integrates an efficient loader, conditioner, and sampler structure for reproducible results. You can restyle images, adjust aesthetics, or test visual variations quickly. Every edit stays true to the original layout, ensuring consistency. Ideal for designers testing looks or visual directions without redoing entire compositions.

Important nodes:

Key nodes in Comfyui HiDream O1 Image ComfyUI Image Editing workflow

HiDreamO1Sampler (#8)

This is the heart of the pipeline where edits are synthesized. Parameters that matter most are output resolution, sampling steps, guidance scale, image-conditioning strength, and seed. Keep resolution aligned with your input’s aspect ratio, raise steps for tougher edits, and balance guidance with conditioning strength to trade off prompt obedience versus source fidelity.

HiDreamO1Conditioning (#9)

Defines what to change and what to avoid. Favor concise, unambiguous instructions in the positive prompt and reserve stylistic or artifact-avoidance terms for the negative prompt. When edits feel too strong or off-target, simplify the instruction or reduce conflicting style words.

HiDreamO1ModelLoader (#2)

Loads the HiDream O1 Image BF16 checkpoint used by the sampler. Use BF16 for a good balance of speed and memory usage, and switch checkpoints when you need a different aesthetic or domain. If you swap models, recheck guidance and conditioning strength, since optimal values can shift across checkpoints.
