Step-by-Step Guide: Deploy PyTorch 2.8 + CUDA 12.8 on Runpod

Getting your PyTorch 2.8 environment running on Runpod is straightforward. Follow these steps to get your GPU instance up and running quickly:

Sign Up and Log In: Create a Runpod account (it’s free to sign up). Simply head to the Runpod homepage and click Sign Up. Verify your email and log in to access the Runpod dashboard.
Start a New GPU Pod: In the Runpod console, navigate to the Pods section and click + Deploy Pod. This begins the pod configuration process where you’ll choose your resources.
Choose a GPU Instance: Select an NVIDIA GPU type for your workload. Runpod offers a range of GPUs (from affordable RTX 4090s to powerful A100/H100 cards) across multiple regions. If you’re training large models (like GPT-style LLMs or high-res diffusion models), you might pick a high-VRAM GPU (e.g., an 80GB A100) for better performance. For smaller projects or testing, a 24GB GPU (like RTX 3090/4090) can suffice. (Tip: Runpod’s Pricing page details costs per GPU — usage is billed by the minute with no hidden ingress/egress fees, so you can scale cost-effectively.)
Select the PyTorch 2.8 + CUDA 12.8 Container: Under Container Image or Pod Template, choose the pre-built PyTorch 2.8 template. You can find it in the Template Gallery (search for “PyTorch 2.8 + CUDA 12.8”). The official image name is runpod/pytorch:2.8.0-py3.11-cuda12.8.1-cudnn-devel-ubuntu, which comes preloaded with PyTorch 2.8, Python 3.11, CUDA 12.8.1 and cuDNN on Ubuntu. This ready-to-run container means no setup — all essential ML libraries and drivers are already installed.
Configure Your Pod (Disk & Volume): Give your pod a name, and set any preferences like container disk size. If you have training data or models to preserve, attach a Network Volume (optional persistent storage) so data isn’t lost when the pod stops. (You can skip the volume for quick experiments, but for longer training jobs or saving results, using a volume is recommended.)
Deploy and Launch: Review your settings, then click Deploy Pod. Runpod will spin up your instance in seconds. The container image is pulled and your pod will transition to a running state. Once it’s running, you’re almost ready to code!
Access the Environment: After deployment, click Connect on your pod. You can open a web-based terminal or IDE (Runpod offers an in-browser shell and even VS Code or Jupyter integrations). At this point, you’re inside the PyTorch 2.8 container environment. Verify things are working by running python and importing PyTorch (import torch) or checking nvidia-smi for GPU details. You now have full root access to an AI-ready VM in the cloud, with PyTorch and CUDA set up and ready to go.

That’s it! In just a few minutes, you’ve launched a cloud GPU with PyTorch 2.8. No drivers to install, no environment conflicts – you can immediately start training models or running scripts. In the next sections, we’ll explore what you can do with this setup on Runpod’s platform.

Fine-Tune LLMs with PyTorch 2.8 on Runpod

One of the most exciting use cases for this environment is fine-tuning large language models (LLMs). With PyTorch 2.8’s cutting-edge features and CUDA 12.8 harnessing NVIDIA’s latest GPUs, you can train or fine-tune models like GPT variants, Llama, or custom transformer models much faster. PyTorch 2.x introduced new performance optimizations (like the torch.compile compiler and support for dynamic shapes) that significantly speed up training workloads . This means quicker iteration when tweaking model hyperparameters or training on new data.

On Runpod, you can take advantage of high-VRAM GPUs (A100, H100, etc.) to handle the memory demands of large models. For example, fine-tuning a 13B+ parameter model or doing distributed training across multiple GPUs becomes feasible – simply select a multi-GPU pod or use Runpod’s Instant Clusters feature to scale out. The benefit of on-demand GPUs is that you only pay for what you use and can shut down the pod when done, avoiding the huge expense of owning such hardware. Many developers use Runpod to fine-tune models with Hugging Face Transformers, DeepSpeed, or PyTorch Lightning, all of which you can install in this container and run smoothly. If your goal is to deploy the fine-tuned model for inference, you can even switch to Runpod’s Serverless platform for serving requests without managing a full VM. In short, PyTorch 2.8 on Runpod gives you a powerful, flexible playground for all your LLM training experiments.

Accelerate Diffusion Model Workflows (Stable Diffusion & More)

Training and running diffusion models (like Stable Diffusion for image generation) is another popular workflow for PyTorch 2.8 on Runpod. Diffusion models are computationally intensive and often require significant GPU memory. By using Runpod’s GPU Cloud, you can get access to GPUs that have the horsepower and VRAM needed for these tasks. For instance, you might fine-tune Stable Diffusion with custom datasets (e.g. DreamBooth training for personalized images) or train LoRA adapters for SDXL. These tasks can easily consume hours or days of compute and demand tens of gigabytes of VRAM – something most local setups struggle with . With Runpod, you can select a high-memory GPU for a few hours, get the job done, and then shut it down. No long-term commitment, no worrying about overheating your own PC.

In the PyTorch 2.8 + CUDA 12.8 container, all the popular libraries for diffusion workflows are compatible. You can install Hugging Face Diffusers, Automatic1111’s Stable Diffusion web UI, or any other tools as needed. Many users launch the Stable Diffusion WebUI template from the Template Gallery, which similarly provides a ready environment. But if you prefer the latest PyTorch 2.8 for maximum performance, our container has you covered – you can still run accelerate, xFormers, and other optimizations to speed up training. Thanks to CUDA 12.8, you’ll leverage improved kernel performance on newer NVIDIA architectures, generating images or training models faster. Whether you’re iterating on generative art projects or researching novel diffusion techniques, Runpod’s on-demand GPUs make it easy to experiment freely.

Train Vision Models at Scale with Ease

Computer vision projects – such as image classification, object detection, or segmentation – also benefit greatly from PyTorch 2.8 on Runpod. Vision datasets can be large (think ImageNet-level scale) and training models like ResNet, EfficientNet, or Vision Transformers can be time-consuming without acceleration. By spinning up a Runpod GPU instance, you get immediate access to a machine that’s tuned for heavy training loads. For example, you might use a Tesla A10 or RTX 4090 for a balance of cost and speed on mid-sized projects, or choose multiple GPUs to train an object detection model with PyTorch Lightning’s distributed training. Runpod lets you scale up or down as needed – start with one GPU for prototyping, then seamlessly upgrade to multi-GPU or a more powerful GPU when you’re ready for the full dataset.

PyTorch 2.8’s improved performance means even vision training loops run faster, so you’ll see model accuracy improvements sooner in your experiments. And because the environment is containerized, you can install OpenCV, TorchVision, MMDetection or any CV libraries without worrying about breaking system dependencies. It’s a reproducible setup – if you need to share your environment with a teammate, they can deploy the same PyTorch 2.8 container on Runpod and get identical results. From data augmentation to training and evaluation, everything can be done within this cloud pod. Once your computer vision model is trained, you can either download the model weights or deploy them on a Runpod serverless endpoint for production inference. In summary, training vision models on Runpod combines the power of PyTorch 2.8 with the convenience of cloud GPUs, giving you speed and flexibility for any CV task.

FAQ

Q: What is the best GPU to use for my training on Runpod?

A: It depends on your model’s needs. For very large models or datasets, GPUs with more VRAM (such as NVIDIA A100 80GB or H100) are recommended to handle the load. For example, fine-tuning a multi-billion-parameter LLM or training high-resolution diffusion models will benefit from the extra memory and throughput of these cards. If you’re training smaller models or doing experimentation, an NVIDIA RTX 4090 (24GB) or even RTX 3090 can be a cost-effective choice. Runpod offers a range of GPUs – you can start with what’s sufficient and easily scale up if you need more power.

Q: How do I keep my data persistent on Runpod?

A: By default, a pod’s container storage is ephemeral (it won’t persist after the pod is terminated). However, you can attach a Network Volume when launching your pod to store data persistently. Any files saved to that volume will remain even if you stop or delete the pod, and you can reattach the volume to new pods later. This is great for storing datasets, checkpoints, or results. Additionally, you can always download important files to your local machine or push them to cloud storage for backup after training.

Q: Should I use a GPU Pod or Runpod Serverless for my project?

A: Use GPU pods for training, interactive development, or any workload that needs a full machine environment (with long-running processes, custom libraries, etc.). Pods are ideal for training sessions that might last hours or days. On the other hand, use Runpod Serverless when you want to deploy models for inference or short jobs that need to scale on demand. Serverless instances spin up automatically in response to requests and shut down when idle, which is perfect for serving a trained model to end-users without paying for an always-on GPU. In many cases, you’ll train your model on a pod, then deploy it via Serverless for production.

Q: Can I use a different container or customize the environment?

A: Absolutely. Runpod allows you to deploy any Docker image by providing the image name in the Advanced options (you can use public images or private ones from your registry). The Template Gallery on Runpod is just a convenient collection of popular environments. If the PyTorch 2.8 + CUDA 12.8 container doesn’t have a library you need, you can install it manually inside the running pod (since you have root access), or you can even build your own image with all your requirements and use that. Runpod also supports creating custom templates for your account, so you can save an environment setup and reuse it easily.

Q: What are some example use cases people run with PyTorch on Runpod?

A: Many users run a variety of AI workflows. Some examples include: fine-tuning transformer models for NLP (e.g., text classification or chatbot finetuning), training image generation models like Stable Diffusion or GANs, doing academic research on novel model architectures, running large-scale hyperparameter searches, and training computer vision models for Kaggle competitions or business projects.
