Welcome to the magical world of Diffusion models! DiffSynth-Studio is an open-source Diffusion model engine developed and maintained by the [ModelScope Community](https://www.modelscope.cn/). We hope to foster technological innovation through framework construction, aggregate the power of the open-source community, and explore the boundaries of generative model technology!

We believe that a well-developed open-source code framework can lower the threshold for technical exploration. We have achieved many [interesting technologies](#innovative-achievements) based on this codebase. Perhaps you also have many wild ideas, and with DiffSynth-Studio, you can quickly realize these ideas. For this reason, we have prepared detailed documentation for developers. We hope that through these documents, developers can understand the principles of Diffusion models, and we look forward to expanding the boundaries of technology together with you.

> DiffSynth-Studio has undergone major version updates, and some old features are no longer maintained. If you need to use old features, please switch to the [last historical version](https://github.com/modelscope/DiffSynth-Studio/tree/afd101f3452c9ecae0c87b79adfa2e22d65ffdc3) before the major version update.
|
||||
|
||||
> Currently, the development personnel of this project are limited, with most of the work handled by [Artiprocher](https://github.com/Artiprocher). Therefore, the progress of new feature development will be relatively slow, and the speed of responding to and resolving issues is limited. We apologize for this and ask developers to understand.
|
||||
- **February 26, 2026** Added full and lora training support for the LTX-2 audio-video generation model. See the [documentation](/docs/en/Model_Details/LTX-2.md) for details.
|
||||
|
||||
- **February 10, 2026** Added inference support for the LTX-2 audio-video generation model. See the [documentation](/docs/en/Model_Details/LTX-2.md) for details. Support for model training will be implemented in the future.
|
||||
|
||||
- **February 2, 2026** The first document of the Research Tutorial series is now available, guiding you through training a small 0.1B text-to-image model from scratch. For details, see the [documentation](/docs/en/Research_Tutorial/train_from_scratch.md) and [model](https://modelscope.cn/models/DiffSynth-Studio/AAAMyModel). We hope DiffSynth-Studio can evolve into a more powerful training framework for Diffusion models.
|
||||
|
||||
- **January 27, 2026**: [Z-Image](https://modelscope.cn/models/Tongyi-MAI/Z-Image) is released, and our [Z-Image-i2L](https://www.modelscope.cn/models/DiffSynth-Studio/Z-Image-i2L) model is released concurrently. You can use it in [ModelScope Studios](https://modelscope.cn/studios/DiffSynth-Studio/Z-Image-i2L). For details, see the [documentation](/docs/zh/Model_Details/Z-Image.md).
|
||||
|
||||
- **January 19, 2026**: Added support for [FLUX.2-klein-4B](https://modelscope.cn/models/black-forest-labs/FLUX.2-klein-4B) and [FLUX.2-klein-9B](https://modelscope.cn/models/black-forest-labs/FLUX.2-klein-9B) models, including training and inference capabilities. [Documentation](/docs/en/Model_Details/FLUX2.md) and [example code](/examples/flux2/) are now available.
|
||||
|
||||
- **January 12, 2026**: We trained and open-sourced a text-guided image layer separation model ([Model Link](https://modelscope.cn/models/DiffSynth-Studio/Qwen-Image-Layered-Control)). Given an input image and a textual description, the model isolates the image layer corresponding to the described content. For more details, please refer to our blog post ([Chinese version](https://modelscope.cn/learn/4938), [English version](https://huggingface.co/blog/kelseye/qwen-image-layered-control)).
|
||||
|
||||
- **December 24, 2025**: Based on Qwen-Image-Edit-2511, we trained an In-Context Editing LoRA model ([Model Link](https://modelscope.cn/models/DiffSynth-Studio/Qwen-Image-Edit-2511-ICEdit-LoRA)). This model takes three images as input (Image A, Image B, and Image C), and automatically analyzes the transformation from Image A to Image B, then applies the same transformation to Image C to generate Image D. For more details, please refer to our blog post ([Chinese version](https://mp.weixin.qq.com/s/41aEiN3lXKGCJs1-we4Q2g), [English version](https://huggingface.co/blog/kelseye/qwen-image-edit-2511-icedit-lora)).
|
||||
|
||||
- **December 9, 2025** We release a wild model based on DiffSynth-Studio 2.0: [Qwen-Image-i2L](https://www.modelscope.cn/models/DiffSynth-Studio/Qwen-Image-i2L) (Image-to-LoRA). This model takes an image as input and outputs a LoRA. Although this version still has significant room for improvement in terms of generalization, detail preservation, and other aspects, we are open-sourcing these models to inspire more innovative research. For more details, please refer to our [blog](https://huggingface.co/blog/kelseye/qwen-image-i2l).

The model hash value is only related to the keys and tensor shapes in the state dict of the model file, and is unrelated to the numerical values of the model parameters, file saving time, and other information. When calculating the model hash value of `.safetensors` format files, `hash_model_file` is almost instantly completed without reading the model parameters. However, when calculating the model hash value of `.bin`, `.pth`, `.ckpt`, and other binary files, all model parameters need to be read, so **we do not recommend developers to continue using these formats of files.**

## Model Loading

`load_model` is the external entry for loading models in `diffsynth.core.loader`. It will call [skip_model_initialization](../../API_Reference/core/vram.md#skipping-model-parameter-initialization) to skip model parameter initialization. If [Disk Offload](../../Pipeline_Usage/VRAM_management.md#disk-offload) is enabled, it calls [DiskMap](../../API_Reference/core/vram.md#state-dict-disk-mapping) for lazy loading. If Disk Offload is not enabled, it calls [load_state_dict](#model-file-loading) to load model parameters. If necessary, it will also call [state dict converter](../../Developer_Guide/Integrating_Your_Model.md#step-2-model-file-format-conversion) for model format conversion. Finally, it calls `model.eval()` to switch to inference mode.

# LTX-2
|
||||
|
||||
LTX-2 is a series of audio-video generation models developed by Lightricks.
|
||||
|
||||
## Installation
|
||||
|
||||
Before using this project for model inference and training, please install DiffSynth-Studio first.
|
||||
|
||||
```shell
|
||||
git clone https://github.com/modelscope/DiffSynth-Studio.git
|
||||
cd DiffSynth-Studio
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
For more information about installation, please refer to [Installation Dependencies](../Pipeline_Usage/Setup.md).
|
||||
|
||||
## Quick Start
|
||||
|
||||
Run the following code to quickly load the [Lightricks/LTX-2](https://www.modelscope.cn/models/Lightricks/LTX-2) model and perform inference. VRAM management has been enabled, and the framework will automatically control model parameter loading based on remaining VRAM. It can run with a minimum of 8GB VRAM.

For base models of LTX-2, offical checkpoint (with model config ModelConfig(model_id="Lightricks/LTX-2", origin_file_pattern="ltx-2-19b-dev.safetensors"))
|
||||
and repackaged checkpoints (with model config ModelConfig(model_id="DiffSynth-Studio/LTX-2-Repackage", origin_file_pattern="*.safetensors")) are both supported.
|
||||
We have repackeged the official checkpoints in DiffSynth-Studio/LTX-2-Repackage repo to support separate loading of different submodules,
|
||||
and avoid redundant memory usage when users only want to use part of the model.

## Model Inference
|
||||
|
||||
Models are loaded through `LTX2AudioVideoPipeline.from_pretrained`, see [Loading Models](../Pipeline_Usage/Model_Inference.md#loading-models) for details.
|
||||
|
||||
Input parameters for `LTX2AudioVideoPipeline` inference include:
|
||||
|
||||
* `prompt`: Prompt describing the content appearing in the video.
|
||||
* `negative_prompt`: Negative prompt describing content that should not appear in the video, default value is `""`.
|
||||
* `cfg_scale`: Classifier-free guidance parameter, default value is 3.0.
|
||||
* `input_images`: List of input images for image-to-video generation.
|
||||
* `input_images_indexes`: Frame index list of input images in the video.
|
||||
* `input_images_strength`: Strength of input images, default value is 1.0.
|
||||
* `denoising_strength`: Denoising strength, range is 0～1, default value is 1.0.
|
||||
* `seed`: Random seed. Default is `None`, which means completely random.
|
||||
* `rand_device`: Computing device for generating random Gaussian noise matrix, default is `"cpu"`. When set to `cuda`, different results will be generated on different GPUs.
|
||||
* `height`: Video height, must be a multiple of 32 (single-stage) or 64 (two-stage).
|
||||
* `width`: Video width, must be a multiple of 32 (single-stage) or 64 (two-stage).
|
||||
* `num_frames`: Number of video frames, default value is 121, must be a multiple of 8 + 1.
|
||||
* `num_inference_steps`: Number of inference steps, default value is 40.
|
||||
* `tiled`: Whether to enable VAE tiling inference, default is `True`. When set to `True`, it can significantly reduce VRAM usage during VAE encoding/decoding stages, with slight errors and minor inference time extension.
|
||||
* `tile_size_in_pixels`: Pixel tiling size during VAE encoding/decoding stages, default is 512.
|
||||
* `tile_overlap_in_pixels`: Pixel tiling overlap size during VAE encoding/decoding stages, default is 128.
|
||||
* `tile_size_in_frames`: Frame tiling size during VAE encoding/decoding stages, default is 128.
|
||||
* `tile_overlap_in_frames`: Frame tiling overlap size during VAE encoding/decoding stages, default is 24.
|
||||
* `use_two_stage_pipeline`: Whether to use two-stage pipeline, default is `False`.
|
||||
* `use_distilled_pipeline`: Whether to use distilled pipeline, default is `False`.
|
||||
* `progress_bar_cmd`: Progress bar, default is `tqdm.tqdm`. Can be set to `lambda x:x` to hide the progress bar.
|
||||
|
||||
If VRAM is insufficient, please enable [VRAM Management](../Pipeline_Usage/VRAM_management.md). We provide recommended low VRAM configurations for each model in the example code, see the table in the previous "Supported Inference Scripts" section.
|
||||
|
||||
## Model Training
|
||||
|
||||
LTX-2 series models are uniformly trained through [`examples/ltx2/model_training/train.py`](https://github.com/modelscope/DiffSynth-Studio/blob/main/examples/ltx2/model_training/train.py), and the script parameters include:
|
||||
|
||||
* General Training Parameters
|
||||
* Dataset Basic Configuration
|
||||
* `--dataset_base_path`: Root directory of the dataset.
|
||||
* `--dataset_metadata_path`: Metadata file path of the dataset.
|
||||
* `--dataset_repeat`: Number of times the dataset is repeated in each epoch.
|
||||
* `--dataset_num_workers`: Number of processes for each DataLoader.
|
||||
* `--data_file_keys`: Field names to be loaded from metadata, usually image or video file paths, separated by `,`.
|
||||
* Model Loading Configuration
|
||||
* `--model_paths`: Paths of models to be loaded. JSON format.
|
||||
* `--model_id_with_origin_paths`: Model IDs with original paths, e.g., `"Wan-AI/Wan2.1-T2V-1.3B:diffusion_pytorch_model*.safetensors"`. Separated by commas.
|
||||
* `--extra_inputs`: Extra input parameters required by the model Pipeline, e.g., extra parameters when training image editing models, separated by `,`.
|
||||
* `--fp8_models`: Models loaded in FP8 format, consistent with `--model_paths` or `--model_id_with_origin_paths` format. Currently only supports models whose parameters are not updated by gradients (no gradient backpropagation, or gradients only update their LoRA).
|
||||
* Training Basic Configuration
|
||||
* `--learning_rate`: Learning rate.
|
||||
* `--num_epochs`: Number of epochs.
|
||||
* `--trainable_models`: Trainable models, e.g., `dit`, `vae`, `text_encoder`.
|
||||
* `--find_unused_parameters`: Whether there are unused parameters in DDP training. Some models contain redundant parameters that do not participate in gradient calculation, and this setting needs to be enabled to avoid errors in multi-GPU training.
|
||||
* `--weight_decay`: Weight decay size, see [torch.optim.AdamW](https://docs.pytorch.org/docs/stable/generated/torch.optim.AdamW.html).
|
||||
* `--task`: Training task, default is `sft`. Some models support more training modes, please refer to the documentation of each specific model.
|
||||
* Output Configuration
|
||||
* `--output_path`: Model saving path.
|
||||
* `--remove_prefix_in_ckpt`: Remove prefix in the state dict of the model file.
|
||||
* `--save_steps`: Interval of training steps to save the model. If this parameter is left blank, the model is saved once per epoch.
|
||||
* LoRA Configuration
|
||||
* `--lora_base_model`: Which model to add LoRA to.
|
||||
* `--lora_target_modules`: Which layers to add LoRA to.
|
||||
* `--lora_rank`: Rank of LoRA.
|
||||
* `--lora_checkpoint`: Path of the LoRA checkpoint. If this path is provided, LoRA will be loaded from this checkpoint.
|
||||
* `--preset_lora_path`: Preset LoRA checkpoint path. If this path is provided, this LoRA will be loaded in the form of being merged into the base model. This parameter is used for LoRA differential training.
|
||||
* `--preset_lora_model`: Model that the preset LoRA is merged into, e.g., `dit`.
|
||||
* Gradient Configuration
|
||||
* `--use_gradient_checkpointing`: Whether to enable gradient checkpointing.
|
||||
* `--use_gradient_checkpointing_offload`: Whether to offload gradient checkpointing to memory.
|
||||
* `--gradient_accumulation_steps`: Number of gradient accumulation steps.
|
||||
* Video Width/Height Configuration
|
||||
* `--height`: Height of the video. Leave `height` and `width` blank to enable dynamic resolution.
|
||||
* `--width`: Width of the video. Leave `height` and `width` blank to enable dynamic resolution.
|
||||
* `--max_pixels`: Maximum pixel area of video frames. When dynamic resolution is enabled, video frames with resolution larger than this value will be downscaled, and video frames with resolution smaller than this value will remain unchanged.
|
||||
* `--num_frames`: Number of frames in the video.
|
||||
* LTX-2 Series Specific Parameters
|
||||
* `--tokenizer_path`: Path of the tokenizer, applicable to text-to-video models, leave blank to automatically download from remote.
|
||||
* `--frame_rate`: frame rate of the training videos.
|
||||
|
||||
We have built a sample video dataset for your testing. You can download this dataset with the following command:
|
||||
|
||||
```shell
|
||||
modelscope download --dataset DiffSynth-Studio/example_video_dataset --local_dir ./data/example_video_dataset
|
||||
```
|
||||
|
||||
We have written recommended training scripts for each model, please refer to the table in the "Model Overview" section above. For how to write model training scripts, please refer to [Model Training](../Pipeline_Usage/Model_Training.md); for more advanced training algorithms, please refer to [Training Framework Detailed Explanation](https://github.com/modelscope/DiffSynth-Studio/tree/main/docs/en/Training/).

Therefore, direct training will quickly cause the model to lose its acceleration capability. The effect of inference with "acceleration configuration" (`num_inference_steps=8`, `cfg_scale=1`) becomes worse, while the effect of inference with "no acceleration configuration" (`num_inference_steps=30`, `cfg_scale=2`) becomes better. The following training and inference schemes can be adopted:

## Loading LoRA
|
||||
|
||||
LoRA is a lightweight model training method that produces a small number of parameters to extend model capabilities. DiffSynth-Studio supports two ways to load LoRA: cold loading and hot loading.
|
||||
|
||||
* Cold loading: When the base model does not have [VRAM management](../Pipeline_Usage/VRAM_management.md) enabled, LoRA will be fused into the base model weights. In this case, inference speed remains unchanged, but LoRA cannot be unloaded after loading.
|
||||
|
||||

|
||||

||||

image.save("image.jpg")
|
||||
```
|
||||
|
||||
* Hot loading: When the base model has [VRAM management](../Pipeline_Usage/VRAM_management.md) enabled, LoRA will not be fused into the base model weights. In this case, inference speed will be slower, but LoRA can be unloaded through `pipe.clear_lora()` after loading.

|
||||
* Training effectiveness is usually strongly correlated with training steps and weakly correlated with epoch count. Therefore, we recommend using the `--save_steps` parameter to save model files at training step intervals.
|
||||
* When data volume * `dataset_repeat` exceeds $10^9$, we observed that the dataset speed becomes significantly slower, which seems to be a `PyTorch` bug. We are not sure if newer versions of `PyTorch` have fixed this issue.
|
||||
* For learning rate `--learning_rate`, it is recommended to set to `1e-4` in LoRA training and `1e-5` in full training.
|
||||
* The training framework does not support batch size > 1. The reasons are complex. See [Q&A: Why doesn't the training framework support batch size > 1?](../QA.md#why-doesnt-the-training-framework-support-batch-size--1)

|
||||
* Some models contain redundant parameters. For example, the text encoding part of the last layer of Qwen-Image's DiT part. When training these models, `--find_unused_parameters` needs to be set to avoid errors in multi-GPU training. For compatibility with community models, we do not intend to remove these redundant parameters.
|
||||
* The loss function value of Diffusion models has little relationship with actual effects. Therefore, we do not record loss function values during training. We recommend setting `--num_epochs` to a sufficiently large value, testing while training, and manually closing the training program after the effect converges.
|
||||
* `--use_gradient_checkpointing` is usually enabled unless GPU VRAM is sufficient; `--use_gradient_checkpointing_offload` is enabled as needed. See [`diffsynth.core.gradient`](../API_Reference/core/gradient.md) for details.

## How to dynamically load LoRA models during inference?
|
||||
|
||||
We support two loading methods for LoRA models. See [LoRA Loading](./Pipeline_Usage/Model_Inference.md#loading-lora) for details:
|
||||
|
||||
* Cold Loading: When [VRAM Management](./Pipeline_Usage/VRAM_management.md) is not enabled for the base model, LoRA will be fused into the base model weights. In this case, inference speed remains unchanged, and LoRA cannot be unloaded after loading.
|
||||
* Hot Loading: When [VRAM Management](./Pipeline_Usage/VRAM_management.md) is enabled for the base model, LoRA will not be fused into the base model weights. In this case, inference speed will slow down, and LoRA can be unloaded after loading via `pipe.clear_lora()`.
|
||||
Therefore, native FP8 precision training technology is extremely immature. We will observe the technological developments in the open-source community.

# Training Models from Scratch
|
||||
|
||||
DiffSynth-Studio's training engine supports training foundation models from scratch. This article introduces how to train a small text-to-image model with only 0.1B parameters from scratch.
|
||||
|
||||
## 1. Building Model Architecture
|
||||
|
||||
### 1.1 Diffusion Model
|
||||
|
||||
From UNet [[1]](https://arxiv.org/abs/1505.04597) [[2]](https://arxiv.org/abs/2112.10752) to DiT [[3]](https://arxiv.org/abs/2212.09748) [[4]](https://arxiv.org/abs/2403.03206), the mainstream model architectures of Diffusion have undergone multiple evolutions. Typically, a Diffusion model's inputs include:
|
||||
|
||||
* Image tensor (`latents`): The encoding of images, generated by the VAE model, containing partial noise
|
||||
* Text tensor (`prompt_embeds`): The encoding of text, generated by the text encoder
|
||||
* Timestep (`timestep`): A scalar used to mark which stage of the Diffusion process we are currently at
|
||||
|
||||
The model's output is a tensor with the same shape as the image tensor, representing the denoising direction predicted by the model. For details about Diffusion model theory, please refer to [Basic Principles of Diffusion Models](../Training/Understanding_Diffusion_models.md). In this article, we build a DiT model with only 0.1B parameters: `AAADiT`.

### 1.2 Encoder-Decoder Models
|
||||
|
||||
Besides the Diffusion model used for denoising, we also need two other models:
|
||||
|
||||
* Text Encoder: Used to encode text into tensors. We adopt the [Qwen/Qwen3-0.6B](https://modelscope.cn/models/Qwen/Qwen3-0.6B) model.
|
||||
* VAE Encoder-Decoder: The encoder part is used to encode images into tensors, and the decoder part is used to decode image tensors into images. We adopt the VAE model from [black-forest-labs/FLUX.2-klein-4B](https://modelscope.cn/models/black-forest-labs/FLUX.2-klein-4B).
|
||||
|
||||
The architectures of these two models are already integrated in DiffSynth-Studio, located at [/diffsynth/models/z_image_text_encoder.py](https://github.com/modelscope/DiffSynth-Studio/blob/main/diffsynth/models/z_image_text_encoder.py) and [/diffsynth/models/flux2_vae.py](https://github.com/modelscope/DiffSynth-Studio/blob/main/diffsynth/models/flux2_vae.py), so we don't need to modify any code.
|
||||
|
||||
## 2. Building Pipeline
|
||||
|
||||
We introduced how to build a model Pipeline in the document [Integrating Pipeline](../Developer_Guide/Building_a_Pipeline.md). For the model in this article, we also need to build a Pipeline to connect the text encoder, Diffusion model, and VAE encoder-decoder.

## 3. Preparing Dataset
|
||||
|
||||
To quickly verify training effectiveness, we use the dataset [Pokemon-First Generation](https://modelscope.cn/datasets/DiffSynth-Studio/pokemon-gen1), which is reproduced from the open-source project [pokemon-dataset-zh](https://github.com/42arch/pokemon-dataset-zh), containing 151 first-generation Pokemon from Bulbasaur to Mew. If you want to use other datasets, please refer to the document [Preparing Datasets](../Pipeline_Usage/Model_Training.md#preparing-datasets) and [`diffsynth.core.data`](../API_Reference/core/data.md).
|
||||
|
||||
```shell
|
||||
modelscope download --dataset DiffSynth-Studio/pokemon-gen1 --local_dir ./data
|
||||
```
|
||||
|
||||
### 4. Start Training
|
||||
|
||||
The training process can be quickly implemented using Pipeline. We have placed the complete code at [../Research_Tutorial/train_from_scratch.py](https://github.com/modelscope/DiffSynth-Studio/blob/main/docs/en/Research_Tutorial/train_from_scratch.py), which can be directly started with `python docs/en/Research_Tutorial/train_from_scratch.py` for single GPU training.
|
||||
|
||||
To enable multi-GPU parallel training, please run `accelerate config` to set relevant parameters, then use the command `accelerate launch docs/en/Research_Tutorial/train_from_scratch.py` to start training.
|
||||
|
||||
This training script has no stopping condition, please manually close it when needed. The model converges after training approximately 60,000 steps, requiring 10-20 hours for single GPU training.

## 5. Verifying Training Results
|
||||
|
||||
If you don't want to wait for the model training to complete, you can directly download [our pre-trained model](https://modelscope.cn/models/DiffSynth-Studio/AAAMyModel).
|
||||
|
||||
```shell
|
||||
modelscope download --model DiffSynth-Studio/AAAMyModel step-600000.safetensors --local_dir models/DiffSynth-Studio/AAAMyModel
|
||||
```
|
||||
|
||||
Loading the model
|
||||
|
||||
```python
|
||||
from diffsynth import load_model
|
||||
|
||||
pipe = AAAImagePipeline.from_pretrained(
|
||||
torch_dtype=torch.bfloat16,
|
||||
device="cuda",
|
||||
model_configs=[
|
||||
ModelConfig(model_id="Qwen/Qwen3-0.6B", origin_file_pattern="model.safetensors"),
|
||||
ModelConfig(model_id="black-forest-labs/FLUX.2-klein-4B", origin_file_pattern="vae/diffusion_pytorch_model.safetensors"),
|
||||
],
|
||||
tokenizer_config=ModelConfig(model_id="Qwen/Qwen3-0.6B", origin_file_pattern="./"),
|
||||
)
|
||||
pipe.dit = load_model(AAADiT, "models/DiffSynth-Studio/AAAMyModel/step-600000.safetensors", torch_dtype=torch.bfloat16, device="cuda")
|
||||
```
|
||||
|
||||
Model inference, generating the first-generation Pokemon "starter trio". At this point, the images generated by the model basically match the training data.
|
||||
|
||||
```python
|
||||
for seed, prompt in enumerate([
|
||||
"green, lizard, plant, Grass, Poison, seed on back, red eyes, smiling expression, short stout limbs, sharp claws",
|
||||
"orange, cream, lizard, Fire, flame on tail tip, large eyes, smiling expression, cream-colored belly patch, sharp claws",
|
||||
"blue, beige, brown, turtle, water type, shell, big eyes, short limbs, curled tail",
|
||||
]):
|
||||
image = pipe(
|
||||
prompt=prompt,
|
||||
negative_prompt=" ",
|
||||
num_inference_steps=30,
|
||||
cfg_scale=10,
|
||||
seed=seed,
|
||||
height=256, width=256,
|
||||
)
|
||||
image.save(f"image_{seed}.jpg")
|
||||
```
|
||||
|
||||
||||
|
||||
|-|-|-|
|
||||
|
||||
Model inference, generating Pokemon with "sharp claws". At this point, different random seeds can produce different image results.
|
||||
|
||||
```python
|
||||
for seed, prompt in enumerate([
|
||||
"sharp claws",
|
||||
"sharp claws",
|
||||
"sharp claws",
|
||||
]):
|
||||
image = pipe(
|
||||
prompt=prompt,
|
||||
negative_prompt=" ",
|
||||
num_inference_steps=30,
|
||||
cfg_scale=10,
|
||||
seed=seed+4,
|
||||
height=256, width=256,
|
||||
)
|
||||
image.save(f"image_sharp_claws_{seed}.jpg")
|
||||
```
|
||||
|
||||
||||
|
||||
|-|-|-|
|
||||
|
||||
Now, we have obtained a 0.1B small text-to-image model. This model can already generate 151 Pokemon, but cannot generate other image content. If you increase the amount of data, model parameters, and number of GPUs based on this, you can train a more powerful text-to-image model!

In the training process of most models, a large amount of computation occurs in "preprocessing," i.e., "computations unrelated to the denoising model," including VAE encoding, text encoding, etc. When the corresponding model parameters are fixed, the results of these computations are repetitive. For each data sample, the computational results are identical across multiple epochs. Therefore, we provide a "split training" feature that can automatically analyze and split the training process.
|

For standard supervised training of ordinary text-to-image models, the splitting process is straightforward. It only requires splitting the computation of all [`Pipeline Units`](../Developer_Guide/Building_a_Pipeline.md#units) into the first stage, storing the computational results to disk, and then reading these results from disk in the second stage for subsequent computations. However, if gradient backpropagation is required during preprocessing, the situation becomes extremely complex. To address this, we introduced a computational graph splitting algorithm to analyze how to split the computation.
