+### Stable Diffusion MoD ControlNet Tile SR Pipeline SDXL
+
+This pipeline implements the [MoD (Mixture-of-Diffusers)]("https://arxiv.org/pdf/2408.06072") tiled diffusion technique and combines it with SDXL's ControlNet Tile process to generate SR images.
+
+This works better with 4x scales, but you can try adjusts parameters to higher scales.

+        Function invoked when calling the pipeline for generation.
+
+        Args:
+            prompt (`str` or `List[str]`, *optional*):
+                The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
+            image (`torch.Tensor`, `PIL.Image.Image`, `np.ndarray`, `List[torch.Tensor]`, `List[PIL.Image.Image]`, `List[np.ndarray]`, *optional*):
+                The initial image to be used as the starting point for the image generation process. Can also accept
+                image latents as `image`, if passing latents directly, they will not be encoded again.
+            control_image (`PipelineImageInput`, *optional*):
+                The ControlNet input condition. ControlNet uses this input condition to generate guidance for Unet.
+                If the type is specified as `torch.Tensor`, it is passed to ControlNet as is. `PIL.Image.Image` can also
+                be accepted as an image. The dimensions of the output image default to `image`'s dimensions. If height
+                and/or width are passed, `image` is resized accordingly. If multiple ControlNets are specified in
+                init, images must be passed as a list such that each element of the list can be correctly batched for
+                input to a single ControlNet.
+            height (`int`, *optional*):
+                The height in pixels of the generated image. If not provided, defaults to the height of `control_image`.
+            width (`int`, *optional*):
+                The width in pixels of the generated image. If not provided, defaults to the width of `control_image`.
+            strength (`float`, *optional*, defaults to 0.9999):
+                Indicates the 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`.
+            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.
+            guidance_scale (`float`, *optional*, defaults to 5.0):
+                Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
+                `guidance_scale` is defined as `w` of equation 2. of [Imagen Paper](https://arxiv.org/pdf/2205.11487.pdf).
+                Guidance scale is enabled by setting `guidance_scale > 1`. Higher guidance scale encourages generating
+                images closely linked to the text `prompt`, usually at the expense of lower image quality.
+            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 `guidance_scale` is
+                less than `1`).
+            num_images_per_prompt (`int`, *optional*, defaults to 1):
+                The number of images to generate per prompt.
+            eta (`float`, *optional*, defaults to 0.0):
+                Corresponds to parameter eta (η) in the DDIM paper: https://arxiv.org/abs/2010.02502. Only applies to
+                [`schedulers.DDIMScheduler`], will be ignored for others.
+            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`.
+            output_type (`str`, *optional*, defaults to `"pil"`):
+                The output format of the generated 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.stable_diffusion.StableDiffusionPipelineOutput`] instead of a
+                plain tuple.
+            cross_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).
+            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 UNet. If multiple ControlNets are specified in init, you can set the
+                corresponding scale as a list.
+            guess_mode (`bool`, *optional*, defaults to `False`):
+                In this mode, the ControlNet encoder will try to recognize the content of the input image even if
+                you remove all prompts. The `guidance_scale` between 3.0 and 5.0 is recommended.
+            control_guidance_start (`float` or `List[float]`, *optional*, defaults to 0.0):
+                The percentage of total steps at which the ControlNet starts applying.
+            control_guidance_end (`float` or `List[float]`, *optional*, defaults to 1.0):
+                The percentage of total steps at which the ControlNet stops applying.
+            control_mode (`int` or `List[int]`, *optional*):
+                The mode of ControlNet guidance. Can be used to specify different behaviors for multiple ControlNets.
+            original_size (`Tuple[int, int]`, *optional*):
+                If `original_size` is not the same as `target_size`, the image will appear to be down- or upsampled.
+                `original_size` defaults to `(height, width)` if not specified. Part of SDXL's micro-conditioning.
+            crops_coords_top_left (`Tuple[int, int]`, *optional*, defaults to (0, 0)):
+                `crops_coords_top_left` can be used to generate an image that appears to be "cropped" from the position
+                `crops_coords_top_left` downwards. Favorable, well-centered images are usually achieved by setting
+                `crops_coords_top_left` to (0, 0). Part of SDXL's micro-conditioning.
+            target_size (`Tuple[int, int]`, *optional*):
+                For most cases, `target_size` should be set to the desired height and width of the generated image. If
+                not specified, it will default to `(height, width)`. Part of SDXL's micro-conditioning.
+            negative_original_size (`Tuple[int, int]`, *optional*):
+                To negatively condition the generation process based on a specific image resolution. Part of SDXL's
+                micro-conditioning.
+            negative_crops_coords_top_left (`Tuple[int, int]`, *optional*, defaults to (0, 0)):
+                To negatively condition the generation process based on a specific crop coordinates. Part of SDXL's
+                micro-conditioning.
+            negative_target_size (`Tuple[int, int]`, *optional*):
+                To negatively condition the generation process based on a target image resolution. It should be the same
+                as the `target_size` for most cases. Part of SDXL's micro-conditioning.
+            aesthetic_score (`float`, *optional*, defaults to 6.0):
+                Used to simulate an aesthetic score of the generated image by influencing the positive text condition.
+                Part of SDXL's micro-conditioning.
+            negative_aesthetic_score (`float`, *optional*, defaults to 2.5):
+                Used to simulate an aesthetic score of the generated image by influencing the negative text condition.
+                Part of SDXL's micro-conditioning.
+            clip_skip (`int`, *optional*):
+                Number of layers to be skipped from CLIP while computing the prompt embeddings. A value of 1 means that
+                the output of the pre-final layer will be used for computing the prompt embeddings.
+            normal_tile_overlap (`int`, *optional*, defaults to 64):
+                Number of overlapping pixels between tiles in consecutive rows.
+            border_tile_overlap (`int`, *optional*, defaults to 128):
+                Number of overlapping pixels between tiles at the borders.
+            max_tile_size (`int`, *optional*, defaults to 1024):
+                Maximum size of a tile in pixels.
+            tile_gaussian_sigma (`float`, *optional*, defaults to 0.3):
+                Sigma parameter for Gaussian weighting of tiles.
+            tile_weighting_method (`str`, *optional*, defaults to "Cosine"):
+                Method for weighting tiles. Options: "Cosine" or "Gaussian".
