+
+        Args:
+            prompt (`str` or `List[str]`, *optional*):
+                The prompt or prompts to guide the image generation.
+            prompt_2 (`str` or `List[str]`, *optional*):
+                The prompt or prompts to be sent to the `tokenizer_2` and `text_encoder_2`.
+            image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
+                The image(s) to inpaint.
+            mask_image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
+                The mask image(s) to use for inpainting. White pixels in the mask will be repainted, while black pixels
+                will be preserved.
+            masked_image_latents (`torch.FloatTensor`, *optional*):
+                Pre-generated masked image latents.
+            control_image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
+                The ControlNet input condition. Image to control the generation.
+            height (`int`, *optional*, defaults to self.default_sample_size * self.vae_scale_factor):
+                The height in pixels of the generated image.
+            width (`int`, *optional*, defaults to self.default_sample_size * self.vae_scale_factor):
+                The width in pixels of the generated image.
+            strength (`float`, *optional*, defaults to 0.6):
+                Conceptually, indicates how much to inpaint the masked area. Must be between 0 and 1.
+            padding_mask_crop (`int`, *optional*):
+                The size of the padding to use when cropping the mask.
+            num_inference_steps (`int`, *optional*, defaults to 28):
+                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 7.0):
+                Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).

+            control_mode (`int` or `List[int]`, *optional*):
+                The mode for the ControlNet. If multiple ControlNets are used, this should be a list.
+            controlnet_conditioning_scale (`float` or `List[float]`, *optional*, defaults to 1.0):
+                The outputs of the ControlNet are multiplied by `controlnet_conditioning_scale` before they are added
+                to the residual in the original transformer.
+            num_images_per_prompt (`int`, *optional*, defaults to 1):
+                The number of images to generate per prompt.

+                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.
+            prompt_embeds (`torch.FloatTensor`, *optional*):
+                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.
+            pooled_prompt_embeds (`torch.FloatTensor`, *optional*):
+                Pre-generated pooled text embeddings.
+            output_type (`str`, *optional*, defaults to `"pil"`):
+                The output format of the generate image. Choose between `PIL.Image` or `np.array`.
+            return_dict (`bool`, *optional*, defaults to `True`):
+                Whether or not to return a [`~pipelines.flux.FluxPipelineOutput`] instead of a plain tuple.
+            joint_attention_kwargs (`dict`, *optional*):
+                Additional keyword arguments to be passed to the joint attention mechanism.
+            callback_on_step_end (`Callable`, *optional*):
+                A function that calls at the end of each denoising step during the inference.
+            callback_on_step_end_tensor_inputs (`List[str]`, *optional*):
+                The list of tensor inputs for the `callback_on_step_end` function.
+            max_sequence_length (`int`, *optional*, defaults to 512):
+                The maximum length of the sequence to be generated.
+
+        Examples:
+
+        Returns:
+            [`~pipelines.flux.FluxPipelineOutput`] or `tuple`: [`~pipelines.flux.FluxPipelineOutput`] if `return_dict`

-            prompt (`str` or `List[str]`, *optional*):
-                The prompt or prompts to guide the image generation.
-            prompt_2 (`str` or `List[str]`, *optional*):
-                The prompt or prompts to be sent to the `tokenizer_2` and `text_encoder_2`.
-            image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
-                The image(s) to inpaint.
-            mask_image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
-                The mask image(s) to use for inpainting. White pixels in the mask will be repainted, while black pixels
-                will be preserved.
-            masked_image_latents (`torch.FloatTensor`, *optional*):
-                Pre-generated masked image latents.
-            control_image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):
-                The ControlNet input condition. Image to control the generation.
-            height (`int`, *optional*, defaults to self.default_sample_size * self.vae_scale_factor):
-                The height in pixels of the generated image.
-            width (`int`, *optional*, defaults to self.default_sample_size * self.vae_scale_factor):
-                The width in pixels of the generated image.
-            strength (`float`, *optional*, defaults to 0.6):
-                Conceptually, indicates how much to inpaint the masked area. Must be between 0 and 1.
-            padding_mask_crop (`int`, *optional*):
-                The size of the padding to use when cropping the mask.
-            num_inference_steps (`int`, *optional*, defaults to 28):
-                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

-            control_mode (`int` or `List[int]`, *optional*):
-                The mode for the ControlNet. If multiple ControlNets are used, this should be a list.
-            controlnet_conditioning_scale (`float` or `List[float]`, *optional*, defaults to 1.0):
-                The outputs of the ControlNet are multiplied by `controlnet_conditioning_scale` before they are added
-                to the residual in the original transformer.
-            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 more [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) to

-            latents (`torch.FloatTensor`, *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.
-            prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.

-                Pre-generated pooled text embeddings.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generate image. Choose between `PIL.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`~pipelines.flux.FluxPipelineOutput`] instead of a plain tuple.
-            joint_attention_kwargs (`dict`, *optional*):
-                Additional keyword arguments to be passed to the joint attention mechanism.

-                The list of tensor inputs for the `callback_on_step_end` function.
-            max_sequence_length (`int`, *optional*, defaults to 512):
-                The maximum length of the sequence to be generated.
-
-        Examples:
-
-        Returns:
-            [`~pipelines.flux.FluxPipelineOutput`] or `tuple`: [`~pipelines.flux.FluxPipelineOutput`] if `return_dict`
-            is True, otherwise a `tuple`. When returning a tuple, the first element is a list with the generated
-            images.

+                The prompt or prompts to be sent to the `tokenizer_2` and `text_encoder_2`.
+            image (`PIL.Image.Image` or `List[PIL.Image.Image]` or `torch.FloatTensor`):

+                The size of the padding to use when cropping the mask.
+            num_inference_steps (`int`, *optional*, defaults to 28):
+                The number of denoising steps. More denoising steps usually lead to a higher quality image at the

+            sigmas (`List[float]`, *optional*):
+                Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in

+            control_mode (`int` or `List[int]`, *optional*):
+                The mode for the ControlNet. If multiple ControlNets are used, this should be a list.
+            controlnet_conditioning_scale (`float` or `List[float]`, *optional*, defaults to 1.0):
+                The outputs of the ControlNet are multiplied by `controlnet_conditioning_scale` before they are added
+                to the residual in the original transformer.
+            num_images_per_prompt (`int`, *optional*, defaults to 1):
+                The number of images to generate per prompt.

+                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.
+            prompt_embeds (`torch.FloatTensor`, *optional*):
+                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.
+            pooled_prompt_embeds (`torch.FloatTensor`, *optional*):
+                Pre-generated pooled text embeddings.
+            output_type (`str`, *optional*, defaults to `"pil"`):
+                The output format of the generate image. Choose between `PIL.Image` or `np.array`.
+            return_dict (`bool`, *optional*, defaults to `True`):
+                Whether or not to return a [`~pipelines.flux.FluxPipelineOutput`] instead of a plain tuple.
+            joint_attention_kwargs (`dict`, *optional*):
+                Additional keyword arguments to be passed to the joint attention mechanism.
+            callback_on_step_end (`Callable`, *optional*):
+                A function that calls at the end of each denoising step during the inference.
+            callback_on_step_end_tensor_inputs (`List[str]`, *optional*):
+                The list of tensor inputs for the `callback_on_step_end` function.
+            max_sequence_length (`int`, *optional*, defaults to 512):
+                The maximum length of the sequence to be generated.

+# Flux Fill ControlNet Pipeline
+
+This implementation of Flux Fill + ControlNet Inpaint combines the fill-style masked editing of FLUX.1-Fill-dev with full ControlNet conditioning. The base image is processed through the Fill model while the ControlNet receives the corresponding conditioning input (depth, canny, pose, etc.), and both outputs are fused during denoising to guide structure and composition.
+
+While FLUX.1-Fill-dev is designed for mask-based edits, it was not originally trained to operate jointly with ControlNet. In practice, this combined setup works well for structured inpainting tasks, though results may vary depending on the conditioning strength and the alignment between the mask and the control input.
