How to extract maximum fidelity
Choose the perfect model checkpoint for your hardware setup and generation needs.
01
1. HiDream-O1-Image (Full Power)
The uncompromising foundation model. Use 50 inference steps with a CFG Scale of 5.0 for maximum aesthetic fidelity and detail.
02
2. HiDream-O1-Image-Dev (Distilled)
Need speed? The Dev variant is distilled for rapid prototyping. Drop the steps to 28 and set CFG to 0.0 for blazing-fast generations.
03
3. Utilize prompt_agent.py
Always run your initial concepts through the built-in prompt agent to let the model optimize spatial awareness before rendering.
04
4. Generate at 2048x2048 Native
Skip the upscaler. HiDream-O1 is built to render Ultra-HD 2K resolution right out of the box. Set your base resolution high.
Advanced architecture for the AI frontier
HiDream-O1 isn't just another fine-tune. It is a fundamental shift in how neural networks understand and process visual data.
Pixel-level Unified Transformer (UiT)
Processes text, images, and conditions in a single, shared token space rather than relying on disjointed external text encoders.
- Eliminates misinterpretation between text and image encoders
- Retains 100% of spatial data lost in traditional pipelines
- Scales efficiently from 8B to 200B+ parameters
Native ComfyUI Integration
No hacky workarounds required. Drop it straight into the industry-standard node interface and start generating immediately.
- Update ComfyUI and load the native HiDream template
- Custom nodes specifically optimized for UiT processing
- Seamless integration with your existing post-processing pipelines
Instruction-Based Editing
Change lighting, swap subjects, or modify styles by simply telling the model what to do. No masks required.
- Understands complex natural language editing commands
- Maintains perfect consistency of unedited regions
- Applies global style transfers flawlessly
Storyboard & Sequence Generation
Generate sequential art and cohesive storyboards with incredible character and environmental consistency across panels.
- Maintains subject identity across multiple generations
- Understands cinematic camera angles and shot types
- Perfect for pre-visualization and comic creation
DPG-Bench Dominance
With a Dense Prompt Alignment score of 89.83, the model captures every single detail in massively complex, paragraph-long prompts.
- Rarely ignores background details or secondary subjects
- Accurately renders precise object counts and colors
- Perfect spatial positioning (left, right, foreground, background)
Future-Proof Foundation
The 8B model is just the beginning. The experimental HiDream-O1-Image-Pro proves this architecture scales up to 200B parameters without bottlenecking.
- A paradigm that will define the next 5 years of AI art
- Massive community support forming around the architecture
- Continuous updates from the Beijing-based HiDream.ai team

Frequently asked questions
Everything you need to know about setting up and deploying HiDream-O1-Image.
HiDream-O1-Image is an advanced 8B parameter AI image generation model created by HiDream. It introduces the Pixel-level Unified Transformer (UiT), merging text, images, and instructions into a single token space without relying on traditional VAEs or external text encoders.
Variational Autoencoders (VAEs) compress images into latent space to save compute, which inherently causes data loss—leading to blurry text, color bleeding, and loss of fine details. By processing in raw pixel space, HiDream-O1 retains 100% of the image fidelity.
The 'Full' model provides the absolute highest visual quality, requiring 50 inference steps and a CFG of 5.0. The 'Dev' model is a distilled version designed for speed, achieving great results in just 28 steps with a CFG of 0.0.
Yes! Unlike many recent high-end models, HiDream-O1-Image is released under the highly permissive MIT License. You have complete freedom to use it for commercial projects, SaaS applications, and enterprise pipelines.
The model repository includes a script called `prompt_agent.py`. It uses reasoning to take your simple prompt ideas and expand them into highly structured, spatially logical prompts tailored perfectly for the UiT architecture.
Yes. HiDream-O1 has native ComfyUI support. Simply update your ComfyUI installation, go to Workflow -> Browse Templates, and select the 'HiDream O1 Full: Image generation' template to start immediately.
