| # QwenImage | |
| Qwen-Image from the Qwen team is an image generation foundation model in the Qwen series that achieves significant advances in complex text rendering and precise image editing. Experiments show strong general capabilities in both image generation and editing, with exceptional performance in text rendering, especially for Chinese. | |
| Qwen-Image comes in the following variants: | |
| | model type | model id | | |
| |:----------:|:--------:| | |
| | Qwen-Image | [`Qwen/Qwen-Image`](https://huggingface.co/Qwen/Qwen-Image) | | |
| | Qwen-Image-Edit | [`Qwen/Qwen-Image-Edit`](https://huggingface.co/Qwen/Qwen-Image-Edit) | | |
| | Qwen-Image-Edit Plus | [Qwen/Qwen-Image-Edit-2509](https://huggingface.co/Qwen/Qwen-Image-Edit-2509) | | |
| > [!TIP] | |
| > See the [Caching](../../optimization/cache) guide to speed up inference by storing and reusing intermediate outputs. | |
| ## LoRA for faster inference | |
| Use a LoRA from `lightx2v/Qwen-Image-Lightning` to speed up inference by reducing the | |
| number of steps. Refer to the code snippet below: | |
| Code | |
| ```py | |
| from diffusers import DiffusionPipeline, FlowMatchEulerDiscreteScheduler | |
| import torch | |
| import math | |
| ckpt_id = "Qwen/Qwen-Image" | |
| # From | |
| # https://github.com/ModelTC/Qwen-Image-Lightning/blob/342260e8f5468d2f24d084ce04f55e101007118b/generate_with_diffusers.py#L82C9-L97C10 | |
| scheduler_config = { | |
| "base_image_seq_len": 256, | |
| "base_shift": math.log(3), # We use shift=3 in distillation | |
| "invert_sigmas": False, | |
| "max_image_seq_len": 8192, | |
| "max_shift": math.log(3), # We use shift=3 in distillation | |
| "num_train_timesteps": 1000, | |
| "shift": 1.0, | |
| "shift_terminal": None, # set shift_terminal to None | |
| "stochastic_sampling": False, | |
| "time_shift_type": "exponential", | |
| "use_beta_sigmas": False, | |
| "use_dynamic_shifting": True, | |
| "use_exponential_sigmas": False, | |
| "use_karras_sigmas": False, | |
| } | |
| scheduler = FlowMatchEulerDiscreteScheduler.from_config(scheduler_config) | |
| pipe = DiffusionPipeline.from_pretrained( | |
| ckpt_id, scheduler=scheduler, torch_dtype=torch.bfloat16 | |
| ).to("cuda") | |
| pipe.load_lora_weights( | |
| "lightx2v/Qwen-Image-Lightning", weight_name="Qwen-Image-Lightning-8steps-V1.0.safetensors" | |
| ) | |
| prompt = "a tiny astronaut hatching from an egg on the moon, Ultra HD, 4K, cinematic composition." | |
| negative_prompt = " " | |
| image = pipe( | |
| prompt=prompt, | |
| negative_prompt=negative_prompt, | |
| width=1024, | |
| height=1024, | |
| num_inference_steps=8, | |
| true_cfg_scale=1.0, | |
| generator=torch.manual_seed(0), | |
| ).images[0] | |
| image.save("qwen_fewsteps.png") | |
| ``` | |
| > [!TIP] | |
| > The `guidance_scale` parameter in the pipeline is there to support future guidance-distilled models when they come up. Note that passing `guidance_scale` to the pipeline is ineffective. To enable classifier-free guidance, please pass `true_cfg_scale` and `negative_prompt` (even an empty negative prompt like " ") should enable classifier-free guidance computations. | |
| ## Multi-image reference with QwenImageEditPlusPipeline | |
| With [QwenImageEditPlusPipeline](/docs/diffusers/pr_13921/en/api/pipelines/qwenimage#diffusers.QwenImageEditPlusPipeline), one can provide multiple images as input reference. | |
| ```py | |
| import torch | |
| from PIL import Image | |
| from diffusers import QwenImageEditPlusPipeline | |
| from diffusers.utils import load_image | |
| pipe = QwenImageEditPlusPipeline.from_pretrained( | |
| "Qwen/Qwen-Image-Edit-2509", torch_dtype=torch.bfloat16 | |
| ).to("cuda") | |
| image_1 = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/grumpy.jpg") | |
| image_2 = load_image("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/peng.png") | |
| image = pipe( | |
| image=[image_1, image_2], | |
| prompt='''put the penguin and the cat at a game show called "Qwen Edit Plus Games"''', | |
| num_inference_steps=50 | |
| ).images[0] | |
| ``` | |
| ## Performance | |
| ### torch.compile | |
| Using `torch.compile` on the transformer provides ~2.4x speedup (A100 80GB: 4.70s → 1.93s): | |
| ```python | |
| import torch | |
| from diffusers import QwenImagePipeline | |
| pipe = QwenImagePipeline.from_pretrained("Qwen/Qwen-Image", torch_dtype=torch.bfloat16).to("cuda") | |
| pipe.transformer = torch.compile(pipe.transformer) | |
| # First call triggers compilation (~7s overhead) | |
| # Subsequent calls run at ~2.4x faster | |
| image = pipe("a cat", num_inference_steps=50).images[0] | |
| ``` | |
| ### Batched Inference with Variable-Length Prompts | |
| When using classifier-free guidance (CFG) with prompts of different lengths, the pipeline properly handles padding through attention masking. This ensures padding tokens do not influence the generated output. | |
| ```python | |
| # CFG with different prompt lengths works correctly | |
| image = pipe( | |
| prompt="A cat", | |
| negative_prompt="blurry, low quality, distorted", | |
| true_cfg_scale=3.5, | |
| num_inference_steps=50, | |
| ).images[0] | |
| ``` | |

| of [Imagen Paper](https://huggingface.co/papers/2205.11487). Classifier-free guidance is enabled by | |
| setting `true_cfg_scale > 1` and a provided `negative_prompt`. Higher guidance scale encourages to | |

| will be used. | |
| - **guidance_scale** (`float`, *optional*, defaults to None) -- | |
| A guidance scale value for guidance distilled models. Unlike the traditional classifier-free guidance | |
| where the guidance scale is applied during inference through noise prediction rescaling, guidance | |
| distilled models take the guidance scale directly as an input parameter during forward pass. Guidance | |
| scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages to generate images | |

| ignored when not using guidance distilled models. To enable traditional classifier-free guidance, | |
| please pass `true_cfg_scale > 1.0` and `negative_prompt` (even an empty negative prompt like " " should | |

| generation. Can be used to tweak the same generation with different prompts. If not provided, a latents | |
| tensor will be generated by sampling using the supplied random `generator`. | |
| - **prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not | |

| - **prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `prompt_embeds`. | |
| - **negative_prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt | |
| weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input | |
| argument. | |
| - **negative_prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `negative_prompt_embeds`. | |
| - **output_type** (`str`, *optional*, defaults to `"pil"`) -- | |
| The output format of the generate image. Choose between | |
| [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. | |
| - **return_dict** (`bool`, *optional*, defaults to `True`) -- | |
| Whether or not to return a `~pipelines.qwenimage.QwenImagePipelineOutput` instead of a plain tuple. | |
| - **attention_kwargs** (`dict`, *optional*) -- | |

| - **callback_on_step_end** (`Callable`, *optional*) -- | |
| A function that calls at the end of each denoising steps during the inference. The function is called | |
| with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int, | |
| callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by | |
| `callback_on_step_end_tensor_inputs`. | |
| - **callback_on_step_end_tensor_inputs** (`list`, *optional*) -- | |
| The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list | |
| will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the | |
| `._callback_tensor_inputs` attribute of your pipeline class. | |
| - **max_sequence_length** (`int` defaults to 512) -- Maximum sequence length to use with the `prompt`.0`~pipelines.qwenimage.QwenImagePipelineOutput` or `tuple``~pipelines.qwenimage.QwenImagePipelineOutput` if `return_dict` is True, otherwise a `tuple`. When | |
| returning a tuple, the first element is a list with the generated images. | |

| - **image** (`torch.Tensor`, `PIL.Image.Image`, `np.ndarray`, `list[torch.Tensor]`, `list[PIL.Image.Image]`, or `list[np.ndarray]`) -- | |
| `Image`, numpy array or tensor representing an image batch to be used as the starting point. For both | |
| numpy array and pytorch tensor, the expected value range is between `[0, 1]` If it's a tensor or a list | |
| or tensors, the expected shape should be `(B, C, H, W)` or `(C, H, W)`. If it is a numpy array or a | |
| list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image | |
| latents as `image`, but if passing latents directly it is not encoded again. | |
| - **true_cfg_scale** (`float`, *optional*, defaults to 1.0) -- | |
| Guidance scale as defined in [Classifier-Free Diffusion | |
| Guidance](https://huggingface.co/papers/2207.12598). `true_cfg_scale` is defined as `w` of equation 2. | |

| The width in pixels of the generated image. This is set to 1024 by default for the best results. | |
| - **strength** (`float`, *optional*, defaults to 1.0) -- | |
| Indicates extent to transform the reference `image`. Must be between 0 and 1. `image` is used as a | |
| starting point and more noise is added the higher the `strength`. The number of denoising steps depends | |
| on the amount of noise initially added. When `strength` is 1, added noise is maximum and the denoising | |
| process runs for the full number of iterations specified in `num_inference_steps`. A value of 1 | |
| essentially ignores `image`. | |
| - **num_inference_steps** (`int`, *optional*, defaults to 50) -- | |
| The number of denoising steps. More denoising steps usually lead to a higher quality image at the | |

| The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`. | |
| instead. | |
| - **negative_prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts not to guide the image generation. If not defined, one has to pass | |
| `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `true_cfg_scale` is | |
| not greater than `1`). | |
| - **image** (`torch.Tensor`, `PIL.Image.Image`, `np.ndarray`, `list[torch.Tensor]`, `list[PIL.Image.Image]`, or `list[np.ndarray]`) -- | |
| `Image`, numpy array or tensor representing an image batch to be used as the starting point. For both | |
| numpy array and pytorch tensor, the expected value range is between `[0, 1]` If it's a tensor or a list | |
| or tensors, the expected shape should be `(B, C, H, W)` or `(C, H, W)`. If it is a numpy array or a | |
| list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image | |
| latents as `image`, but if passing latents directly it is not encoded again. | |
| - **true_cfg_scale** (`float`, *optional*, defaults to 1.0) -- | |
| Guidance scale as defined in [Classifier-Free Diffusion | |
| Guidance](https://huggingface.co/papers/2207.12598). `true_cfg_scale` is defined as `w` of equation 2. | |
| of [Imagen Paper](https://huggingface.co/papers/2205.11487). Classifier-free guidance is enabled by | |
| setting `true_cfg_scale > 1` and a provided `negative_prompt`. Higher guidance scale encourages to | |
| generate images that are closely linked to the text `prompt`, usually at the expense of lower image | |
| quality. | |
| - **mask_image** (`torch.Tensor`, `PIL.Image.Image`, `np.ndarray`, `list[torch.Tensor]`, `list[PIL.Image.Image]`, or `list[np.ndarray]`) -- | |
| `Image`, numpy array or tensor representing an image batch to mask `image`. White pixels in the mask | |
| are repainted while black pixels are preserved. If `mask_image` is a PIL image, it is converted to a | |
| single channel (luminance) before use. If it's a numpy array or pytorch tensor, it should contain one | |
| color channel (L) instead of 3, so the expected shape for pytorch tensor would be `(B, 1, H, W)`, `(B, | |
| H, W)`, `(1, H, W)`, `(H, W)`. And for numpy array would be for `(B, H, W, 1)`, `(B, H, W)`, `(H, W, | |
| 1)`, or `(H, W)`. | |
| - **masked_image_latents** (`torch.Tensor`, `list[torch.Tensor]`) -- | |
| `Tensor` representing an image batch to mask `image` generated by VAE. If not provided, the mask | |
| latents tensor will be generated by `mask_image`. | |
| - **height** (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor) -- | |
| The height in pixels of the generated image. This is set to 1024 by default for the best results. | |
| - **width** (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor) -- | |
| The width in pixels of the generated image. This is set to 1024 by default for the best results. | |
| - **padding_mask_crop** (`int`, *optional*, defaults to `None`) -- | |
| The size of margin in the crop to be applied to the image and masking. If `None`, no crop is applied to | |
| image and mask_image. If `padding_mask_crop` is not `None`, it will first find a rectangular region | |
| with the same aspect ration of the image and contains all masked area, and then expand that area based | |
| on `padding_mask_crop`. The image and mask_image will then be cropped based on the expanded area before | |
| resizing to the original image size for inpainting. This is useful when the masked area is small while | |
| the image is large and contain information irrelevant for inpainting, such as background. | |
| - **strength** (`float`, *optional*, defaults to 1.0) -- | |
| Indicates extent to transform the reference `image`. Must be between 0 and 1. `image` is used as a | |
| starting point and more noise is added the higher the `strength`. The number of denoising steps depends | |
| on the amount of noise initially added. When `strength` is 1, added noise is maximum and the denoising | |
| process runs for the full number of iterations specified in `num_inference_steps`. A value of 1 | |
| essentially ignores `image`. | |
| - **num_inference_steps** (`int`, *optional*, defaults to 50) -- | |
| The number of denoising steps. More denoising steps usually lead to a higher quality image at the | |
| expense of slower inference. | |
| - **sigmas** (`list[float]`, *optional*) -- | |
| Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in | |
| their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed | |
| will be used. | |
| - **guidance_scale** (`float`, *optional*, defaults to None) -- | |
| A guidance scale value for guidance distilled models. Unlike the traditional classifier-free guidance | |
| where the guidance scale is applied during inference through noise prediction rescaling, guidance | |
| distilled models take the guidance scale directly as an input parameter during forward pass. Guidance | |
| scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages to generate images | |
| that are closely linked to the text `prompt`, usually at the expense of lower image quality. This | |
| parameter in the pipeline is there to support future guidance-distilled models when they come up. It is | |
| ignored when not using guidance distilled models. To enable traditional classifier-free guidance, | |
| please pass `true_cfg_scale > 1.0` and `negative_prompt` (even an empty negative prompt like " " should | |
| enable classifier-free guidance computations). | |
| - **num_images_per_prompt** (`int`, *optional*, defaults to 1) -- | |
| The number of images to generate per prompt. | |
| - **generator** (`torch.Generator` or `list[torch.Generator]`, *optional*) -- | |
| One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) | |
| to make generation deterministic. | |
| - **latents** (`torch.Tensor`, *optional*) -- | |
| Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image | |
| generation. Can be used to tweak the same generation with different prompts. If not provided, a latents | |
| tensor will be generated by sampling using the supplied random `generator`. | |
| - **prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not | |
| provided, text embeddings will be generated from `prompt` input argument. | |
| - **prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `prompt_embeds`. | |
| - **negative_prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt | |
| weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input | |
| argument. | |
| - **negative_prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `negative_prompt_embeds`. | |
| - **output_type** (`str`, *optional*, defaults to `"pil"`) -- | |
| The output format of the generate image. Choose between | |
| [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. | |
| - **return_dict** (`bool`, *optional*, defaults to `True`) -- | |
| Whether or not to return a `~pipelines.qwenimage.QwenImagePipelineOutput` instead of a plain tuple. | |
| - **attention_kwargs** (`dict`, *optional*) -- | |
| A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under | |
| `self.processor` in | |
| [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py). | |
| - **callback_on_step_end** (`Callable`, *optional*) -- | |
| A function that calls at the end of each denoising steps during the inference. The function is called | |
| with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int, | |
| callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by | |
| `callback_on_step_end_tensor_inputs`. | |
| - **callback_on_step_end_tensor_inputs** (`list`, *optional*) -- | |
| The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list | |
| will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the | |
| `._callback_tensor_inputs` attribute of your pipeline class. | |
| - **max_sequence_length** (`int` defaults to 512) -- Maximum sequence length to use with the `prompt`.0`~pipelines.qwenimage.QwenImagePipelineOutput` or `tuple``~pipelines.qwenimage.QwenImagePipelineOutput` if `return_dict` is True, otherwise a `tuple`. When | |
| returning a tuple, the first element is a list with the generated images. | |
| Function invoked when calling the pipeline for generation. | |

| or tensors, the expected shape should be `(B, C, H, W)` or `(C, H, W)`. If it is a numpy array or a | |
| list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image | |
| latents as `image`, but if passing latents directly it is not encoded again. | |
| - **prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`. | |
| instead. | |
| - **negative_prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts not to guide the image generation. If not defined, one has to pass | |
| `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `true_cfg_scale` is | |
| not greater than `1`). | |
| - **true_cfg_scale** (`float`, *optional*, defaults to 1.0) -- | |
| true_cfg_scale (`float`, *optional*, defaults to 1.0): Guidance scale as defined in [Classifier-Free | |
| Diffusion Guidance](https://huggingface.co/papers/2207.12598). `true_cfg_scale` is defined as `w` of | |
| equation 2. of [Imagen Paper](https://huggingface.co/papers/2205.11487). Classifier-free guidance is | |
| enabled by setting `true_cfg_scale > 1` and a provided `negative_prompt`. Higher guidance scale | |
| encourages to generate images that are closely linked to the text `prompt`, usually at the expense of | |
| lower image quality. | |
| - **height** (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor) -- | |
| The height in pixels of the generated image. This is set to 1024 by default for the best results. | |

| Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in | |
| their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed | |
| will be used. | |
| - **guidance_scale** (`float`, *optional*, defaults to None) -- | |
| A guidance scale value for guidance distilled models. Unlike the traditional classifier-free guidance | |
| where the guidance scale is applied during inference through noise prediction rescaling, guidance | |
| distilled models take the guidance scale directly as an input parameter during forward pass. Guidance | |
| scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages to generate images | |
| that are closely linked to the text `prompt`, usually at the expense of lower image quality. This | |
| parameter in the pipeline is there to support future guidance-distilled models when they come up. It is | |
| ignored when not using guidance distilled models. To enable traditional classifier-free guidance, | |
| please pass `true_cfg_scale > 1.0` and `negative_prompt` (even an empty negative prompt like " " should | |
| enable classifier-free guidance computations). | |

| The number of images to generate per prompt. | |
| - **generator** (`torch.Generator` or `list[torch.Generator]`, *optional*) -- | |

| Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image | |
| generation. Can be used to tweak the same generation with different prompts. If not provided, a latents | |
| tensor will be generated by sampling using the supplied random `generator`. | |
| - **prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not | |
| provided, text embeddings will be generated from `prompt` input argument. | |
| - **prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `prompt_embeds`. | |
| - **negative_prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt | |
| weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input | |
| argument. | |
| - **negative_prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `negative_prompt_embeds`. | |
| - **output_type** (`str`, *optional*, defaults to `"pil"`) -- | |
| The output format of the generate image. Choose between | |
| [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. | |
| - **return_dict** (`bool`, *optional*, defaults to `True`) -- | |
| Whether or not to return a `~pipelines.qwenimage.QwenImagePipelineOutput` instead of a plain tuple. | |

| - **callback_on_step_end** (`Callable`, *optional*) -- | |
| A function that calls at the end of each denoising steps during the inference. The function is called | |
| with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int, | |
| callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by | |
| `callback_on_step_end_tensor_inputs`. | |
| - **callback_on_step_end_tensor_inputs** (`list`, *optional*) -- | |
| The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list | |
| will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the | |
| `._callback_tensor_inputs` attribute of your pipeline class. | |
| - **max_sequence_length** (`int` defaults to 512) -- Maximum sequence length to use with the `prompt`.0`~pipelines.qwenimage.QwenImagePipelineOutput` or `tuple``~pipelines.qwenimage.QwenImagePipelineOutput` if `return_dict` is True, otherwise a `tuple`. When | |
| returning a tuple, the first element is a list with the generated images. | |
| Function invoked when calling the pipeline for generation. | |

| `Image`, numpy array or tensor representing an image batch to be used as the starting point. For both | |
| numpy array and pytorch tensor, the expected value range is between `[0, 1]` If it's a tensor or a list | |
| or tensors, the expected shape should be `(B, C, H, W)` or `(C, H, W)`. If it is a numpy array or a | |
| list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image | |
| latents as `image`, but if passing latents directly it is not encoded again. | |
| - **prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`. | |
| instead. | |
| - **negative_prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts not to guide the image generation. If not defined, one has to pass | |
| `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `true_cfg_scale` is | |
| not greater than `1`). | |
| - **true_cfg_scale** (`float`, *optional*, defaults to 1.0) -- | |
| true_cfg_scale (`float`, *optional*, defaults to 1.0): Guidance scale as defined in [Classifier-Free | |
| Diffusion Guidance](https://huggingface.co/papers/2207.12598). `true_cfg_scale` is defined as `w` of | |
| equation 2. of [Imagen Paper](https://huggingface.co/papers/2205.11487). Classifier-free guidance is | |
| enabled by setting `true_cfg_scale > 1` and a provided `negative_prompt`. Higher guidance scale | |
| encourages to generate images that are closely linked to the text `prompt`, usually at the expense of | |
| lower image quality. | |
| - **mask_image** (`torch.Tensor`, `PIL.Image.Image`, `np.ndarray`, `list[torch.Tensor]`, `list[PIL.Image.Image]`, or `list[np.ndarray]`) -- | |
| `Image`, numpy array or tensor representing an image batch to mask `image`. White pixels in the mask | |
| are repainted while black pixels are preserved. If `mask_image` is a PIL image, it is converted to a | |
| single channel (luminance) before use. If it's a numpy array or pytorch tensor, it should contain one | |
| color channel (L) instead of 3, so the expected shape for pytorch tensor would be `(B, 1, H, W)`, `(B, | |
| H, W)`, `(1, H, W)`, `(H, W)`. And for numpy array would be for `(B, H, W, 1)`, `(B, H, W)`, `(H, W, | |
| 1)`, or `(H, W)`. | |
| - **masked_image_latents** (`torch.Tensor`, `list[torch.Tensor]`) -- | |

| latents tensor will ge generated by `mask_image`. | |
| - **height** (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor) -- | |
| The height in pixels of the generated image. This is set to 1024 by default for the best results. | |
| - **width** (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor) -- | |
| The width in pixels of the generated image. This is set to 1024 by default for the best results. | |
| - **padding_mask_crop** (`int`, *optional*, defaults to `None`) -- | |
| The size of margin in the crop to be applied to the image and masking. If `None`, no crop is applied to | |
| image and mask_image. If `padding_mask_crop` is not `None`, it will first find a rectangular region | |
| with the same aspect ration of the image and contains all masked area, and then expand that area based | |
| on `padding_mask_crop`. The image and mask_image will then be cropped based on the expanded area before | |
| resizing to the original image size for inpainting. This is useful when the masked area is small while | |
| the image is large and contain information irrelevant for inpainting, such as background. | |
| - **strength** (`float`, *optional*, defaults to 1.0) -- | |
| Indicates extent to transform the reference `image`. Must be between 0 and 1. `image` is used as a | |
| starting point and more noise is added the higher the `strength`. The number of denoising steps depends | |
| on the amount of noise initially added. When `strength` is 1, added noise is maximum and the denoising | |
| process runs for the full number of iterations specified in `num_inference_steps`. A value of 1 | |
| essentially ignores `image`. | |
| - **num_inference_steps** (`int`, *optional*, defaults to 50) -- | |
| The number of denoising steps. More denoising steps usually lead to a higher quality image at the | |
| expense of slower inference. | |
| - **sigmas** (`list[float]`, *optional*) -- | |
| Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in | |
| their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed | |
| will be used. | |
| - **guidance_scale** (`float`, *optional*, defaults to None) -- | |
| A guidance scale value for guidance distilled models. Unlike the traditional classifier-free guidance | |
| where the guidance scale is applied during inference through noise prediction rescaling, guidance | |
| distilled models take the guidance scale directly as an input parameter during forward pass. Guidance | |
| scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages to generate images | |

| ignored when not using guidance distilled models. To enable traditional classifier-free guidance, | |
| please pass `true_cfg_scale > 1.0` and `negative_prompt` (even an empty negative prompt like " " should | |
| enable classifier-free guidance computations). | |
| - **num_images_per_prompt** (`int`, *optional*, defaults to 1) -- | |
| The number of images to generate per prompt. | |
| - **generator** (`torch.Generator` or `list[torch.Generator]`, *optional*) -- | |
| One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) | |
| to make generation deterministic. | |
| - **latents** (`torch.Tensor`, *optional*) -- | |
| Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image | |

| - **negative_prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt | |
| weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input | |
| argument. | |
| - **negative_prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `negative_prompt_embeds`. | |
| - **output_type** (`str`, *optional*, defaults to `"pil"`) -- | |
| The output format of the generate image. Choose between | |
| [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. | |
| - **return_dict** (`bool`, *optional*, defaults to `True`) -- | |

| [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py). | |
| - **callback_on_step_end** (`Callable`, *optional*) -- | |
| A function that calls at the end of each denoising steps during the inference. The function is called | |
| with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int, | |
| callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by | |

| The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list | |
| will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the | |
| `._callback_tensor_inputs` attribute of your pipeline class. | |
| - **max_sequence_length** (`int` defaults to 512) -- Maximum sequence length to use with the `prompt`.0`~pipelines.qwenimage.QwenImagePipelineOutput` or `tuple``~pipelines.qwenimage.QwenImagePipelineOutput` if `return_dict` is True, otherwise a `tuple`. When | |

| `Image`, numpy array or tensor representing an image batch to be used as the starting point. For both | |
| numpy array and pytorch tensor, the expected value range is between `[0, 1]` If it's a tensor or a list | |
| or tensors, the expected shape should be `(B, C, H, W)` or `(C, H, W)`. If it is a numpy array or a | |
| list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image | |
| latents as `image`, but if passing latents directly it is not encoded again. | |
| - **prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`. | |
| instead. | |
| - **negative_prompt** (`str` or `list[str]`, *optional*) -- | |
| The prompt or prompts not to guide the image generation. If not defined, one has to pass | |
| `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `true_cfg_scale` is | |
| not greater than `1`). | |
| - **true_cfg_scale** (`float`, *optional*, defaults to 1.0) -- | |
| true_cfg_scale (`float`, *optional*, defaults to 1.0): Guidance scale as defined in [Classifier-Free | |
| Diffusion Guidance](https://huggingface.co/papers/2207.12598). `true_cfg_scale` is defined as `w` of | |
| equation 2. of [Imagen Paper](https://huggingface.co/papers/2205.11487). Classifier-free guidance is | |
| enabled by setting `true_cfg_scale > 1` and a provided `negative_prompt`. Higher guidance scale | |
| encourages to generate images that are closely linked to the text `prompt`, usually at the expense of | |
| lower image quality. | |
| - **layers** (`int`, *optional*, defaults to 4) -- | |
| Number of latent layers to generate for the layered output. | |
| - **num_inference_steps** (`int`, *optional*, defaults to 50) -- | |
| The number of denoising steps. More denoising steps usually lead to a higher quality image at the | |
| expense of slower inference. | |
| - **sigmas** (`list[float]`, *optional*) -- | |
| Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in | |
| their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed | |
| will be used. | |
| - **guidance_scale** (`float`, *optional*, defaults to None) -- | |
| A guidance scale value for guidance distilled models. Unlike the traditional classifier-free guidance | |
| where the guidance scale is applied during inference through noise prediction rescaling, guidance | |
| distilled models take the guidance scale directly as an input parameter during forward pass. Guidance | |
| scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages to generate images | |
| that are closely linked to the text `prompt`, usually at the expense of lower image quality. This | |
| parameter in the pipeline is there to support future guidance-distilled models when they come up. It is | |
| ignored when not using guidance distilled models. To enable traditional classifier-free guidance, | |
| please pass `true_cfg_scale > 1.0` and `negative_prompt` (even an empty negative prompt like " " should | |
| enable classifier-free guidance computations). | |
| - **num_images_per_prompt** (`int`, *optional*, defaults to 1) -- | |
| The number of images to generate per prompt. | |
| - **generator** (`torch.Generator` or `list[torch.Generator]`, *optional*) -- | |
| One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) | |

| - **latents** (`torch.Tensor`, *optional*) -- | |
| Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image | |
| generation. Can be used to tweak the same generation with different prompts. If not provided, a latents | |
| tensor will be generated by sampling using the supplied random `generator`. | |
| - **prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not | |
| provided, text embeddings will be generated from `prompt` input argument. | |
| - **prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `prompt_embeds`. | |
| - **negative_prompt_embeds** (`torch.Tensor`, *optional*) -- | |
| Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt | |
| weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input | |
| argument. | |
| - **negative_prompt_embeds_mask** (`torch.Tensor`, *optional*) -- | |
| Attention mask for `negative_prompt_embeds`. | |
| - **output_type** (`str`, *optional*, defaults to `"pil"`) -- | |
| The output format of the generate image. Choose between | |
| [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. | |
| - **return_dict** (`bool`, *optional*, defaults to `True`) -- | |
| Whether or not to return a `~pipelines.qwenimage.QwenImagePipelineOutput` instead of a plain tuple. | |
| - **attention_kwargs** (`dict`, *optional*) -- | |
| A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under | |
| `self.processor` in | |
| [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py). | |
| - **callback_on_step_end** (`Callable`, *optional*) -- | |
| A function that calls at the end of each denoising steps during the inference. The function is called | |
| with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int, | |
| callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by | |
| `callback_on_step_end_tensor_inputs`. | |
| - **callback_on_step_end_tensor_inputs** (`List`, *optional*) -- | |
| The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list | |
| will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the | |
| `._callback_tensor_inputs` attribute of your pipeline class. | |
| - **max_sequence_length** (`int` defaults to 512) -- Maximum sequence length to use with the `prompt`. | |
| - **resolution** (`int`, *optional*, defaults to 640) -- | |
| using different bucket in (640, 1024) to determin the condition and output resolution | |
| - **cfg_normalize** (`bool`, *optional*, defaults to `False`) -- | |
| whether enable cfg normalization. | |
| - **use_en_prompt** (`bool`, *optional*, defaults to `False`) -- | |
| automatic caption language if user does not provide caption0`~pipelines.qwenimage.QwenImagePipelineOutput` or `tuple``~pipelines.qwenimage.QwenImagePipelineOutput` if `return_dict` is True, otherwise a `tuple`. When | |
| returning a tuple, the first element is a list with the generated images. | |
