HiDream.ai officially released its latest open source image generation model - HiDream-I1 on April 7, 2025. This powerful image generation model, with its 17B parameter scale, excellent image quality and leading benchmark results, marks a new height in the field of open source image generation.
1. Excellent image quality
HiDream-I1 supports image generation in various styles, including realistic style, cartoon style and artistic style, and has obtained SOTA (State-of-the-Art) results in the HPSv2.1 review, and the generated images are highly consistent with human aesthetics.
2. First-class prompt word compliance ability
In GenEval and DPG benchmarks, HiDream-I1 surpasses all other open source image generation models, performing well, and being able to accurately understand and execute text prompts entered by users.
3. Fully open source
The model is released under the MIT license, which is free to use, modify and distribute by any developer, supporting the widespread development of academic research and innovative applications.
4. Business friendly
The images generated by HiDream-I1 are not only suitable for personal projects and scientific research, but can also be applied to commercial fields, providing users with great flexibility.
To meet the needs of different users, HiDream-I1 offers multiple versions, including the full version, the development version and the fast version. Each version is optimized based on the inference step and computing resources, and is suitable for different generation scenarios:
| Model name | Inference steps | Features | Where to find it (Hugging Face Repository Link) |
|---|---|---|---|
| HiDream-I1 - Full Version | 50 | Full version, best image quality | HiDream-I1 -Full |
| HiDream-I1 -Dev | 28 | Development version, balances speed and effect | HiDream-I1 -Dev |
| HiDream-I1 - Fast | 16 | Speedy version, suitable for scenes where pictures are needed quickly | HiDream-I1 -Fast |
Pursuing the ultimate picture quality? Select "Full Version".
Hope you have both speed and effect? "Development Edition" is your dish.
Need a real-time generation or quick preview? The "Quick Version" can satisfy you.
HiDream-I1 adopts a DiT model of Hybrid Expert Architecture (MoE), combining dual-stream MMDiT blocks and single-stream DiT blocks to efficiently allocate computing resources through dynamic routing mechanisms. In addition, the model integrates a variety of advanced text encoders, such as OpenCLIP ViT-bigG, OpenAI CLIP ViT-L, T5-XXL and Llama-3.1-8B-Instruct, which greatly improves semantic comprehension capabilities and generates images that are more in line with expectations.
If you want to experience the HiDream-I1 model, you can access its GitHub repository and follow the detailed installation and usage guide. You can also download the corresponding model version directly from Hugging Face and choose the version that best suits your needs.
Tip: Flash Attention is required to use this model, and it is recommended to use CUDA version 12.4. Make sure you have sufficient network connection and disk space, especially the Llama-3.1-8B-Instruct component that the model depends on.
