+# Reproducibility
+
+Before reading about reproducibility for Diffusers, it is strongly recommended to take a look at 
+[PyTorch's statement about reproducibility](https://pytorch.org/docs/stable/notes/randomness.html).
+
+PyTorch states that 
+> *completely reproducible results are not guaranteed across PyTorch releases, individual commits, or different platforms.*
+While one can never expect the same results across platforms, one can expect results to be reproducible 
+across releases, platforms, etc... within a certain tolerance. However, this tolerance strongly varies 
+depending on the diffusion pipeline and checkpoint.
+
+In the following, we show how to best control sources of randomness for diffusion models.
+
+## Inference
+
+During inference, diffusion pipelines heavily rely on random sampling operations, such as the creating the 
+gaussian noise tensors to be denoised and adding noise to the scheduling step.
+
+Let's have a look at an example. We run the [DDIM pipeline](./api/pipelines/ddim.mdx) 
+for just two inference steps and return a numpy tensor to look into the numerical values of the output.
+
+```python
+from diffusers import DDIMPipeline
+import numpy as np
+
+model_id = "google/ddpm-cifar10-32"
+
+# load model and scheduler
+ddim = DDIMPipeline.from_pretrained(model_id)
+
+# run pipeline for just two steps and return numpy tensor
+image = ddim(num_inference_steps=2, output_type="np").images
+print(np.abs(image).sum())
+```
+
+Running the above prints a value of 1464.2076, but running it again prints a different 
+value of 1495.1768. What is going on here? Every time the pipeline is run, gaussian noise 
+is created and step-wise denoised. To create the gaussian noise with [`torch.randn`](https://pytorch.org/docs/stable/generated/torch.randn.html), a different random seed is taken every time, thus leading to a different result.
+This is a desired property of diffusion pipelines, as it means that the pipeline can create a different random image every time it is run. In many cases, one would like to generate the exact same image of a certain 
+run, for which case an instance of a [PyTorch generator](https://pytorch.org/docs/stable/generated/torch.randn.html) has to be passed:
+
+```python
+import torch
+from diffusers import DDIMPipeline
+import numpy as np
+
+model_id = "google/ddpm-cifar10-32"
+
+# load model and scheduler
+ddim = DDIMPipeline.from_pretrained(model_id)
+
+# create a generator for reproducibility
+generator = torch.Generator(device="cpu").manual_seed(0)
+
+# run pipeline for just two steps and return numpy tensor
+image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
+print(np.abs(image).sum())
+```
+
+Running the above always prints a value of 1491.1711 - also upon running it again because we 
+define the generator object to be passed to all random functions of the pipeline.
+
+If you run this code snippet on your specific hardware and version, you should get a similar, if not the same, result.
+
+<Tip>
+
+It might be a bit unintuitive at first to pass `generator` objects to the pipelines instead of 
+just integer values representing the seed, but this is the recommended design when dealing with 
+probabilistic models in PyTorch as generators are *random states* that are advanced and can thus be 
+passed to multiple pipelines in a sequence.
+
+</Tip>
+
+Great! Now, we know how to write reproducible pipelines, but it gets a bit trickier since the above example only runs on the CPU. How do we also achieve reproducibility on GPU? 
+In short, one should not expect full reproducibility across different hardware when running pipelines on GPU 
+as matrix multiplications are less deterministic on GPU than on CPU and diffusion pipelines tend to require
+a lot of matrix multiplications. Let's see what we can do to keep the randomness within limits across 
+different GPU hardware.
+
+To achieve maximum speed performance, it is recommended to create the generator directly on GPU when running 
+the pipeline on GPU:
+
+```python
+import torch
+from diffusers import DDIMPipeline
+import numpy as np
+
+model_id = "google/ddpm-cifar10-32"
+
+# load model and scheduler
+ddim = DDIMPipeline.from_pretrained(model_id)
+ddim.to("cuda")
+
+# create a generator for reproducibility
+generator = torch.Generator(device="cuda").manual_seed(0)
+
+# run pipeline for just two steps and return numpy tensor
+image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
+print(np.abs(image).sum())
+```
+
+Running the above now prints a value of 1389.8634 - even though we're using the exact same seed! 
+This is unfortunate as it means we cannot reproduce the results we achieved on GPU, also on CPU.
+Nevertheless, it should be expected since the GPU uses a different random number generator than the CPU.
+
+To circumvent this problem, we created a [`randn_tensor`](#diffusers.utils.randn_tensor) function, which can create random noise 
+on the CPU and then move the tensor to GPU if necessary. The function is used everywhere inside the pipelines allowing the user to **always** pass a CPU generator even if the pipeline is run on GPU:
+
+```python
+import torch
+from diffusers import DDIMPipeline
+import numpy as np
+
+model_id = "google/ddpm-cifar10-32"
+
+# load model and scheduler
+ddim = DDIMPipeline.from_pretrained(model_id)
+ddim.to("cuda")
+
+# create a generator for reproducibility
+generator = torch.manual_seed(0)
+
+# run pipeline for just two steps and return numpy tensor
+image = ddim(num_inference_steps=2, output_type="np", generator=generator).images
+print(np.abs(image).sum())
+```
+
+Running the above now prints a value of 1491.1713, much closer to the value of 1491.1711 when 
+the pipeline is fully run on the CPU.
+
+<Tip>
+
+As a consequence, we recommend always passing a CPU generator if Reproducibility is important.
+The loss of performance is often neglectable, but one can be sure to generate much more similar 
+values than if the pipeline would have been run on CPU.
+
+</Tip>
+
+Finally, we noticed that more complex pipelines, such as [`UnCLIPPipeline`] are often extremely 
+susceptible to precision error propagation and thus one cannot expect even similar results across 
+different GPU hardware or PyTorch versions. In such cases, one has to make sure to run 
+exactly the same hardware and PyTorch version for full Reproducibility.
