VRAM Requirements
| Precision | Approximate VRAM |
|---|---|
| BF16 (this repo) | 17 – 20 GB |
| FP16 | 17 – 20 GB |
| FP8 Mixed | ~10 GB |
A GPU with at least 20 GB VRAM is recommended for comfortable use at full 2048 × 2048 resolution. 24 GB cards (RTX 3090/4090, A5000, etc.) will have no issues.
Quick Start — ComfyUI
1. Install the Custom Node
cd ComfyUI/custom_nodes
git clone https://github.com/Saganaki22/HiDream_O1-ComfyUI
pip install -r HiDream_O1-ComfyUI/requirements.txt
Or install via ComfyUI Manager by searching for HiDream O1.
2. Download the Weights
huggingface-cli download drbaph/HiDream-O1-Image-BF16 \
--local-dir ComfyUI/models/diffusion_models/HiDream-O1-Image-bf16
3. Load in ComfyUI
Open ComfyUI and use the workflow provided in the custom node repository. Point the model loader to HiDream-O1-Image-bf16.
About HiDream-O1-Image
HiDream-O1-Image is a natively unified image generative foundation model built on a Pixel-level Unified Transformer (UiT) — no external VAEs, no disjoint text encoders. It encodes raw pixels, text, and task-specific conditions in a single shared token space, supporting:
- Text-to-image generation up to 2,048 × 2,048
- Instruction-based image editing
- Subject-driven personalization (multi-reference IP)
- Long-text and multilingual text rendering
At only 9B parameters it matches or exceeds much larger open-source DiTs and leading closed-source models. It debuted at #8 in the Artificial Analysis Text to Image Arena (2026-05-05).
Key Features
- 🧬 Pixel-Level Unified Transformer — end-to-end on raw pixels, no VAE, no disjoint text encoder
- 🎨 One Model, Many Tasks — T2I, editing, personalization, storyboard generation
- 🧠 Reasoning-Driven Prompt Agent — built-in "thinking" agent that resolves layout and rendering before generation
- 🖼️ Native High Resolution — direct synthesis up to 2,048 × 2,048
- ⚡ 9B Parameters — performance parity with models many times larger
Model Variants
| Repo | Precision | VRAM | Inference Steps |
|---|---|---|---|
| drbaph/HiDream-O1-Image-BF16 (this repo) | BF16 | 17–20 GB | 50 |
| drbaph/HiDream-O1-Image-FP16 | FP16 | 17–20 GB | 50 |
| drbaph/HiDream-O1-Image-FP8 | FP8 Mixed | ~10 GB | 50 |
| HiDream-ai/HiDream-O1-Image | Original | — | 50 |
| HiDream-ai/HiDream-O1-Image-Dev | Original Dev | — | 28 |
Benchmark Results (from original model)
GenEval (compositional generation) — HiDream-O1-Image scores 0.90 overall at 9B params, second only to the 200B+ Pro variant and ahead of GPT Image 2 (0.89).
DPG-Bench (dense prompt alignment) — Overall score 89.83, ranking second behind the Pro variant.
HPSv3 (human preference) — Overall score 10.37, outperforming GPT Image 2 (10.21) and Nano Banana 2.0 (10.01).
