HiDream-E1 Demo HiDream-E1 is an interactive image editing large model officially open-sourced by HiDream-ai, built based on HiDream-I1. It allows you to edit images using natural language. The model is released under the MIT License, supporting use in personal projects, scientific research, and commercial applications. In combination with the previously released hidream-i1, it enables creative capabilities from image generation to editing.

If you have not installed ComfyUI, please refer to the ComfyUI System Requirements section to install ComfyUI.If you find missing nodes when loading the workflow file below, it may be due to the following situations:
  1. You are not using the latest Development (Nightly) version of ComfyUI.
  2. You are using the Stable (Release) version or Desktop version of ComfyUI (which does not include the latest feature updates).
  3. You are using the latest Commit version of ComfyUI, but some nodes failed to import during startup.
Please make sure you have successfully updated ComfyUI to the latest Development (Nightly) version. See: How to Update ComfyUI section to learn how to update ComfyUI.
All the models involved in this guide can be found here. Except for the Diffusion model, E1 and E1.1 use the same models. The corresponding workflow files also include the relevant model information. You can choose to manually download and save the models, or follow the workflow prompts to download them after loading the workflow. It is recommended to use E1.1. This model requires a large amount of VRAM to run. Please refer to the relevant sections for specific VRAM requirements. Diffusion Model You do not need to download both models. Since E1.1 is an iterative version based on E1, our tests show that its quality and performance are significantly improved compared to E1. Text Encoder: VAE
This is the VAE model for Flux. If you have used the Flux workflow before, you may have already downloaded this file.

HiDream E1.1 ComfyUI Native Workflow Example

E1.1 is an updated version released on July 16, 2025. This version supports dynamic 1-megapixel resolution, and the workflow uses the Scale Image to Total Pixels node to dynamically adjust the input image to 1 million pixels.
Here are the VRAM usage references during testing:
  1. A100 40GB (VRAM usage 95%): First generation: 211s, second generation: 73s
  2. 4090D 24GB (VRAM usage 98%)
  • Full version: Out of memory
  • FP8_e4m3fn_fast (VRAM 98%) First generation: 120s, second generation: 91s

2. Step-by-step Guide to Running the HiDream-e1 Workflow

hidream_e1_1_guide Follow these steps to run the workflow:
  1. Make sure the Load Diffusion Model node loads the hidream_e1_1_bf16.safetensors model.
  2. Make sure the four corresponding text encoders in QuadrupleCLIPLoader are loaded correctly:
    • clip_l_hidream.safetensors
    • clip_g_hidream.safetensors
    • t5xxl_fp8_e4m3fn_scaled.safetensors
    • llama_3.1_8b_instruct_fp8_scaled.safetensors
  3. Make sure the Load VAE node uses the ae.safetensors file.
  4. In the Load Image node, load the provided input or your desired image.
  5. In the Empty Text Encoder(Positive) node, enter the modifications you want to make to the image.
  6. In the Empty Text Encoder(Negative) node, enter the content you do not want to appear in the image.
  7. Click the Run button, or use the shortcut Ctrl(cmd) + Enter to execute image generation.

​
3. Additional Notes on the Workflow

  • Since HiDream E1.1 supports dynamic input with a total of 1 million pixels, the workflow uses Scale Image to Total Pixels to process and convert all input images, which may cause the aspect ratio to differ from the original input image.
  • When using the fp16 version of the model, in actual tests, the full version ran out of memory on both A100 40GB and 4090D 24GB, so the workflow is set by default to use fp8_e4m3fn_fast for inference.

HiDream E1 ComfyUI Native Workflow Example

E1 is a model released on April 28, 2025. This model only supports 768*768 resolution.
For reference, this workflow takes about 500s for the first run and 370s for the second run with 28 sampling steps on Google Colab L4 with 22.5GB VRAM.

2. Complete the HiDream-e1 Workflow Step by Step

hidream_e1_full_step_guide Follow these steps to complete the workflow:
  1. Make sure the Load Diffusion Model node has loaded the hidream_e1_full_bf16.safetensors model
  2. Ensure that the four corresponding text encoders are correctly loaded in the QuadrupleCLIPLoader
    • clip_l_hidream.safetensors
    • clip_g_hidream.safetensors
    • t5xxl_fp8_e4m3fn_scaled.safetensors
    • llama_3.1_8b_instruct_fp8_scaled.safetensors
  3. Make sure the Load VAE node is using the ae.safetensors file
  4. Load the input image we downloaded earlier in the Load Image node
  5. (Important) Enter the prompt for how you want to modify the image in the Empty Text Encoder(Positive) node
  6. Click the Run button, or use the shortcut Ctrl(cmd) + Enter to generate the image

Additional Notes on ComfyUI HiDream-e1 Workflow

  • You may need to modify the prompt multiple times or generate multiple times to get better results
  • This model has difficulty maintaining consistency when changing image styles, so try to make your prompts as complete as possible
  • As the model supports a resolution of 768*768, in actual testing with other dimensions, the image performance is poor or even significantly different at other dimensions
