The Best Way to Access B200 GPUs for AI Research in the Cloud

AI researchers are always on the lookout for the fastest hardware to train larger models and speed up inference. NVIDIA’s B200 GPU (based on the new Blackwell architecture) represents the cutting edge, surpassing the previous H100 and A100 GPUs in memory capacity, throughput, and efficiency. In this guide, we’ll explain what the B200 is and how it improves upon H100/A100, discuss key use cases, and provide a step-by-step walkthrough to spin up a B200 GPU instance on RunPod’s cloud (with tips on containers, storage, and automation). By the end, you’ll know the optimal way to leverage B200 GPUs for your AI projects – and how RunPod makes it easy.

What Are NVIDIA B200 GPUs (Blackwell) and Why Are They Better than H100/A100?

The NVIDIA B200 is a next-generation Tensor Core GPU based on the Blackwell architecture (successor to Hopper H100). It delivers major improvements in memory, bandwidth, and compute performance over the H100 (Hopper) and A100 (Ampere) generation GPUs:

  • Memory Capacity: B200 GPUs come with 192 GB of HBM3e memory, over 2× the memory of H100 (80 GB) and far above A100 (40–80 GB) . This huge memory (effectively ~180 GB usable on cloud instances ) allows training larger models and batch sizes without running out of VRAM. Researchers can fit massive model checkpoints or larger portions of datasets in GPU memory, reducing off-chip transfers.
  • Memory Bandwidth: Each B200 delivers up to 8 TB/s of memory bandwidth – that’s 2.5× the bandwidth of H100 (~3.2 TB/s) and 4× A100’s (2 TB/s). In practice, this means data can be fed to the compute cores much faster. For memory-bound workloads (like transformer models with large attention matrices), B200 GPUs spend less time waiting on data and more time doing computation.
  • Compute Performance: NVIDIA dramatically boosted the lower-precision AI math throughput in B200. Thanks to Blackwell’s design (208 billion transistors on a cutting-edge 4N process) and a dual-die “GPU superchip” approach, the B200 achieves roughly 2× the training throughput of an H100 in FP32/TF32, FP16, and new FP8 formats . It even introduces FP4 precision support, reaching 18 petaFLOPS at FP4 (which H100/A100 do not support) . This means faster training steps and higher teraflops for deep learning workloads. For example, Blackwell’s design sacrifices some 64-bit capability in favor of “heavily increased Tensor Core performance in FP32 and below,” yielding unparalleled mixed-precision performance gains .
  • Training and Inference Speedups: On real-world benchmarks, the leap is significant. NVIDIA reports that a DGX B200 system (8× B200) delivers 3× the training performance and 15× the inference performance of a DGX H100 system . Even per GPU, that translates to substantial speedups. In one large language model benchmark (a 1.8 trillion-parameter GPT-MoE), a single B200 GPU achieved ~15× higher inference throughput and ~3× faster training speedup compared to a single H100 . This kind of generational jump is a game-changer for AI researchers pushing the limits.
  • Power Efficiency: Despite its extreme performance, the B200 is more efficient in performance-per-watt. NVIDIA’s Blackwell architecture uses advanced packaging (NVLink Chip-to-Chip connectivity at 10 TB/s) and better power management. In large deployments, this yields a lower total cost of ownership – estimates suggest up to 12× better TCO for B200 versus H100 in enterprise AI clusters . In other words, to achieve the same throughput as one B200, you’d need multiple older GPUs, consuming far more power. One NVIDIA analysis even showed a Blackwell-based pod reducing energy use 25× for the same LLM inference workload compared to H100 systems . For cloud users, this efficiency can translate into cost savings when renting by the hour.

As shown above, a GPT-MoE 1.8T model sees around 15× higher inference throughput and 3× faster training per GPU on an HGX B200 (Blackwell) system versus HGX H100 (Hopper) . This illustrates the massive performance leap B200 offers for real-world AI workloads.

In summary, the B200 brings massive memory (192 GB vs 80 GB), huge bandwidth (8 TB/s), and ~2×–3× more AI compute than its predecessors, plus new low-precision capabilities that supercharge transformer model training and inference. It’s the ultimate GPU for deep learning as of 2025. Next, let’s look at what kinds of projects benefit most from this powerhouse.

Primary Use Cases for B200 GPUs in AI Research

Given its top-tier specs, the NVIDIA B200 is ideally suited for demanding AI research tasks. Here are the primary use cases where B200 GPUs shine:

Large-Scale Model Training

For training very large models (think hundreds of billions of parameters, or multi-modal networks with huge data), B200 GPUs enable a new level of scale. The large 192 GB memory means you can train models that wouldn’t fit on 80 GB H100s without model parallelism or sharding. This simplifies training setups for giant models. Moreover, with roughly double the throughput of H100 in mixed precision, a cluster of B200s can drastically shorten training times for cutting-edge research models. Whether you’re training an LLM, a mixture-of-experts model, or a sprawling vision transformer, B200s let you iterate faster. In fact, Blackwell-generation GPUs are designed to handle models up to trillions of parameters (the architecture can scale to support LLMs on the order of 10 trillion params) . Researchers working on the next GPT-4 or PaLM-size model will find B200’s capabilities indispensable for feasible training times.

Fine-Tuning Foundation Models

Not every project needs to train a model from scratch – often, you’ll be fine-tuning a foundation model (like Llama 2, GPT-J, Stable Diffusion, etc.). B200 GPUs excel here as well by drastically reducing fine-tuning time, especially on larger model checkpoints. You can load very large pretrained models fully into memory (for example, a 70B parameter model in half precision, or even larger if using optimized formats/quantization), and still have headroom for training data. This avoids the overhead of model parallelism across multiple smaller GPUs. A B200 can handle fine-tuning tasks that might otherwise require two or three H100s working in tandem. Additionally, the improved throughput means you can run more training iterations per hour – useful for hyperparameter sweeps or tuning multiple models. Fine-tuning a foundation model that took 4 hours on an A100 might complete in a fraction of that time on B200. The net result is faster research cycles: you spend more time experimenting and less time waiting on training jobs.

High-Throughput Inference and Deployment

The B200 isn’t just for training – it’s also a beast for inference, especially at scale. If you need to deploy an AI model to serve many users or run very heavy inference workloads (such as large batch processing or real-time responses from a big transformer model), the B200 offers unparalleled throughput. Its support for FP8/INT8 and new FP4 precision means you can serve models with lower precision for huge speedups without significant loss in accuracy. Blackwell GPUs were described as “extremely effective and revolutionary in inference performance,” showing an order-of-magnitude speedup vs previous cards . For example, a single B200 can achieve what used to require a fleet of GPUs – useful for powering things like real-time chatbots, recommendation systems, or batch inference on petabyte-scale datasets. Also, thanks to the large VRAM, a B200 can host multiple model copies or handle multiple requests in parallel via techniques like MIG (Multi-Instance GPU) if needed. In cloud deployments, you might run one B200 and serve thousands of queries per second for an LLM, where previously you’d need to load-balance across many smaller GPUs. The bottom line: for inference-bound applications and production deployments (e.g. an API serving an LLM or a stable diffusion generator with high QPS), B200 offers both the throughput and memory to maximize performance.

Provisioning a B200 GPU Pod on RunPod (Step-by-Step)

Now that we know the why of B200 GPUs, let’s dive into how to access one. RunPod’s cloud platform makes it straightforward to spin up a B200 instance (pod) on demand. Follow these steps to provision a B200 GPU pod for your project:

  1. Log In to RunPod and Open the GPU Cloud Console: Sign into your RunPod account (it’s free to sign up if you haven’t already) and navigate to the GPU Cloud dashboard (where you manage Pods). This is the interface where you can launch and manage cloud GPU instances (Pods) for your workloads.
  2. Choose a Region and Cloud Type (Secure vs Community): Decide where and how you want your B200 pod to run. RunPod offers two types of environments for pods :
    • Secure Cloud – Professionally maintained Tier 3/4 datacenters with high reliability and security. Choose this for mission-critical or enterprise workloads.
    • Community Cloud – A network of community-provided GPUs (peer-to-peer) that are vetted and connected via RunPod. These tend to be more cost-effective. (As of now, B200 instances may be primarily available on Secure Cloud given their high-end nature.)
    • Select a geographic region close to you or your data source for best performance, then pick Secure Cloud or Community Cloud depending on your needs for stability vs price.
  3. Select the B200 GPU Instance: In the pod configuration, you’ll need to select the GPU type. Look for “NVIDIA B200” in the list of available GPUs. RunPod’s GPU offerings include a wide range (from consumer GPUs up to the latest enterprise cards), and the B200 will typically be labeled with its specs (e.g. 180 GB VRAM, 28 vCPUs, etc.) . Choose the B200 option. Tip: You’ll see the hourly rate when selecting – B200 pods on RunPod Secure Cloud are around $7.99/hour as of this writing (check RunPod’s pricing page for up-to-date pricing). It’s a premium GPU, but you only pay by the minute while your pod is running. You can also select how many GPUs you want (for multi-GPU pods, if supported) and adjust CPU/RAM if the interface allows.
  4. Pick or Supply a Container Image: RunPod uses containerized environments for pods, meaning you will launch the B200 inside a Docker container. You have two main choices here:
    • Select an Official Template: RunPod provides ready-to-go images (templates) with popular AI frameworks (PyTorch, TensorFlow, Jupyter notebooks, etc.) which are tested on their platform. This is the easiest route – simply choose a template that suits your task.
    • Use a Custom Docker Image: If you have a specific environment in mind, you can provide any Docker image (from Docker Hub or a registry). RunPod lets you deploy any container you want, supporting both public and private image repositories . Just enter the image name (and tag). For example, you might use an image like pytorch/pytorch:2.1.0-cuda12.2-cudnn8-runtime to get a recent PyTorch with CUDA that supports Blackwell. If building your own image, ensure it’s built with a recent CUDA toolkit/New NVIDIA drivers to recognize the B200 (CUDA 12+ should support it). You can refer to RunPod’s documentation on Docker container setup for guidance on crafting a custom environment.
  5. Configure Storage and Networking Options: Next, you’ll want to set up any storage and ports before launching:
    • Persistent Storage (Volumes): If your project needs datasets, models, or checkpoints, you can attach a persistent volume to the pod. RunPod allows adding network volumes that retain data even after the pod is stopped, so you don’t have to re-upload or lose work. Simply specify the size of the volume you need (in GB). The volume will be mounted (often at /workspace or similar) in your container. This is highly recommended for large training runs – you might, for instance, mount a 500 GB volume with your dataset or use it to save checkpoints. (Persistent volumes incur a small monthly cost per GB, e.g. around $0.05–$0.07 per GB/month , but they enable durable storage for your pod) .
    • Expose Ports: If you plan to use interactive tools or serve an app from your B200 pod, set up the necessary ports. Common examples: expose port 8888 for Jupyter Notebook/Lab, port 22 for SSH access, or port 6006 for TensorBoard. In the RunPod UI, you can usually specify which container ports should be accessible. For instance, to run Jupyter, you’d expose 8888 and then you can open the notebook interface through RunPod’s forwarded URL. Exposing port 22 is useful if you want to SSH or connect VS Code remotely. (Make sure your container actually runs an SSH service in that case – more on that in the FAQ.)
  6. Launch the B200 Pod and Wait for Initialization: Double-check your settings, then hit the Deploy/Launch button. RunPod will provision the B200 GPU for you and spin up the container. On Secure Cloud, this involves allocating a machine with the B200 – the startup time can be a couple of minutes. If your chosen container image isn’t already cached on that host, it will be pulled from the registry. Large images (several GB) can add a few more minutes on first launch. In our experience, cold start times are usually 2–3 minutes (sometimes longer if the image download is huge) . However, RunPod’s platform uses a FlashBoot technology that caches popular container images to reduce pull times, so subsequent launches or common images may start in just seconds . You can monitor the pod status in the console; it will transition from “pending” to “running” when ready. (Pro tip: To minimize wait, use a lean base image or one that RunPod likely caches, and keep your persistent volume attached for quick restarts.)
  7. Connect to Your B200 Instance and Start Working: Once the pod is running, you can access it in several ways. The RunPod web interface provides a web terminal (shell) you can open in your browser to execute commands on the pod. If you enabled Jupyter, you can click the provided URL to open the Jupyter interface and start coding. For SSH or other remote development, you can copy the connection details from the pod’s info (RunPod may give an “SSH over TCP” command if you exposed port 22). From there, you’re free to use the B200 as you would any Linux server with an NVIDIA GPU – install your libraries (if not pre-installed), load data, and launch training scripts. Congratulations, you now have a powerful B200 GPU at your fingertips in the cloud!

Note: Don’t forget to shut down the pod when you’re done to stop billing. You can stop or terminate the pod via the console or CLI. When stopped, your persistent volume data will remain saved, and you can restart later when you need the GPU again.

Automating and Orchestrating B200 Workloads on RunPod (CLI & API)

One advantage of using RunPod for AI research is the ability to automate workflows. If you need to launch jobs, manage multiple pods, or integrate cloud GPUs into your pipeline, RunPod provides both a command-line interface (CLI) tool and a REST API for orchestration.

  • RunPod CLI (runpodctl): RunPod offers an open-source CLI called runpodctl that lets you manage pods programmatically from your terminal . With the CLI, you can do things like create a pod, monitor its status, upload/download files, and shut it down – all with simple commands or scripts. This is great for automation; for example, you could write a bash or Python script to spin up a B200 pod, execute a training script on it, then terminate the pod when done (perhaps triggered as part of your CI/CD or research pipeline). Every RunPod pod comes with runpodctl pre-installed (and even a pod-specific API key injected) , so you can also orchestrate from within a running pod (though typically you’d run the CLI from your local environment or a head node). To use the CLI locally, you can install it via npm or download it from RunPod’s docs . For instance, using the CLI you might run:

runpodctl pods create --gpu-type=B200 --cloud=secure --image=pytorch/pytorch:2.1.0-cuda12.2-runtime

  • (plus additional flags for volume, ports, etc.) to programmatically launch a B200. The CLI provides a lot of flexibility for power users and can be integrated into automation tools. Check out RunPod’s docs for a full CLI reference and examples.
  • RunPod REST API: Anything you can do in the web UI can also be done via RESTful API calls. RunPod’s API allows you to manage pod lifecycles, query status, and even handle serverless endpoints through HTTP requests . This is ideal for building custom tooling or when using languages/environments where a CLI isn’t convenient. For example, you could write a Python script that hits the RunPod API to launch a B200 pod, periodically check if a training job is complete, then shut it down – all using HTTPS calls with your API key. RunPod provides API documentation (including a GraphQL API) and even language-specific SDKs (Python, JavaScript, Go, etc.) for easier integration . With the API, you could incorporate cloud GPU provisioning into a larger application – for instance, automatically spinning up B200 pods to handle peak inference loads, or creating on-demand training clusters for an experiment and tearing them down afterwards. The API also enables advanced orchestration scenarios like launching multiple B200 pods as a cluster for distributed training (you could coordinate them with an orchestration tool or script). In short, if you need to automate it, the API is your friend.

Using the CLI or API, AI engineers can treat RunPod’s cloud like an extension of their local environment – you can script “bring up a B200, run my code, shut it down” in a reproducible way. This is especially useful for ephemeral training jobs or when you want to integrate B200 acceleration into notebooks and applications on-demand. (For example, you might use the API to spin up a pod only when a certain job is queued, to optimize costs.)

Internal Links: For more details, you can explore RunPod’s official pages on available GPU cloud instances (which highlights all GPU types including B200), the RunPod pricing page for cost information, and the RunPod docs on containers if you plan to customize your environment.

Finally, let’s address some frequently asked questions specific to using B200 GPUs on RunPod.

FAQ

Q: Are there researcher or student discounts for B200 pods on RunPod?

A: Yes – RunPod offers credit programs for startups, students, and researchers. Academic users can apply for free GPU credits (up to $25,000) to support their work . In practice, this means if you’re a qualified researcher or student, you could get a significant amount of B200 usage covered by RunPod’s credits or grants. RunPod has programs like RunPod for Academic Research and RunPod for Startups, so be sure to check those out on their site (and apply) if you need cloud GPU time for a research project or course work. Aside from credits, RunPod also occasionally provides promotional discounts or referral bonuses that anyone can use. These can offset the cost of using high-end GPUs like the B200. Always reach out to RunPod or check their “Pricing” page for any available research discounts – they explicitly support academic institutions and want to empower research teams with GPUs.

Q: Can I use persistent cloud storage to keep large datasets and checkpoints?

A: Absolutely. RunPod’s platform provides persistent storage volumes that you can attach to your B200 pods. When launching a pod, you can add a Network Volume of whatever size you need (and you’ll be charged a low monthly rate per GB for it). This volume persists independently of the pod’s lifecycle, so you can stop or terminate the pod and your data remains intact for the next session . This is perfect for storing large datasets, pre-trained model weights, or training checkpoints. For example, you might upload your dataset to a 200 GB volume once, and then attach that volume each time you start a B200 pod – avoiding repeated data transfers. Or after training, save your model checkpoint to the volume, then shut down the pod; you can later spin up a new pod (even a different GPU type) and immediately access those files. The persistent volume behaves like an external drive mounted inside the container. Just remember that container disk vs. volume differ: anything in the container’s filesystem that isn’t on a persistent volume will vanish when the pod is terminated. So use the volume for anything you want to keep. In summary, yes – persistent cloud storage is available and highly recommended for large-scale AI workflows on RunPod.

Q: What remote development tools work with B200 pods (e.g., VS Code, Jupyter)?

A: You can use all your favorite remote dev tools with a RunPod B200 pod, as these pods are essentially Linux servers with internet access. Common options:

  • VS Code Remote SSH: RunPod pods support SSH access (you can enable a public SSH port as described earlier). You can generate an SSH key, add it to your RunPod account, and run an SSH server in the pod . Then, using VS Code’s Remote SSH extension, connect to the pod’s IP/port. This lets you edit files on the B200 instance right from VS Code, just as if it were a remote VM. RunPod even documents how to connect VSCode to a pod for a seamless IDE experience . Many users develop directly on the cloud GPU using this method.
  • Jupyter Notebooks/Lab: If your container comes with Jupyter (or you install it), you can run a Jupyter notebook server on the pod (e.g. jupyter lab --ip=0.0.0.0 --port=8888). By exposing the port (8888) as we did in setup, you get a URL to access Jupyter in your browser. This is great for interactive exploration or demoing results. The B200’s power will be fully available in the notebook for training or inference.
  • SSH Terminal & Others: You can of course use plain SSH in a terminal or tools like scp/rsync for file transfer (after setting up the SSH daemon as per documentation). Tools like tmux or screen can be used within the pod for long-running processes you want to detach from. If you prefer Jupyter VS Code integration, VS Code can also attach to a running Jupyter server on the pod by entering the remote kernel URL. Additionally, you could run a service like RStudio Server, VS Code Server, or any web-based IDE on a different port and access it similarly.

In short, any remote development tool that can connect via web or SSH can work with RunPod pods. The key steps are just exposing the port and running the corresponding service in the container. RunPod’s flexibility means you’re not locked into one interface – you can choose CLI, notebooks, SSH, or even mount the volume locally via rclone if you just want the data. Many users combine these: for instance, using VS Code for coding and a Jupyter notebook for interactive plotting on the same pod. So feel free to use whatever workflow you’re comfortable with – the B200 in the cloud can accommodate it.

Leveraging a cutting-edge GPU like the NVIDIA B200 in the cloud can dramatically accelerate your AI research. With RunPod’s easy-to-use platform, you get on-demand access to this hardware without the usual complexity – simply launch a B200 pod, develop or run your experiments, and only pay for what you use. The combination of B200’s performance and RunPod’s flexibility (containers, automation, and cost optimizations) provides an ideal solution for training large models, fine-tuning AI systems, or deploying high-throughput inference services. We hope this guide helps you confidently get started with B200 GPUs on RunPod. Happy researching, and may your models train faster than ever!
