If you have been comparing GPU cloud providers and keep seeing the same three names come up - Vast.ai, RunPod and Novita - you are not imagining things. Each has carved out a distinct position in the market and they suit genuinely different use cases. This guide breaks down the honest differences so you can make the right choice for your workload rather than defaulting to whichever one you heard about first.

What each platform actually does

Understanding the fundamental difference between these three platforms saves a lot of confusion.

RunPod is a managed GPU cloud platform. You rent GPU instances, the infrastructure is handled for you, and you get a consistent developer experience. It suits teams who need to run their own models, training jobs or custom inference pipelines and want a reliable managed environment to do it in.

Vast.ai is a GPU marketplace. You are renting compute from a network of independent hosts, some of which are verified datacenters and some of which are individual operators. The cheapest listings come from unverified hosts and that price difference reflects a genuine reliability trade-off. It suits cost-conscious teams who are willing to manage more operational complexity in exchange for lower rates.

Novita is different from both. Rather than selling raw GPU compute, Novita gives you access to over 200 pre-deployed AI models through a simple API - covering language models, image generation, video, speech and more. You do not manage infrastructure at all. You make an API call and get a result. It suits developers building AI-powered products who need cheap, reliable access to models without the overhead of running their own GPU instances.

If you need to train models or run custom inference pipelines, you want RunPod or Vast.ai. If you need to use existing models in your product without managing infrastructure, you want Novita.

Pricing compared honestly

GPU pricing on Vast.ai varies by listing because independent hosts set their own rates, so check live offers. The catch is that the effective cost on unverified hosts is higher once you factor in downtime and failed runs. For short experimental jobs that is manageable. For production workloads it erodes the saving quickly.

RunPod lists fixed rates, with H100 PCIe at $2.89 per hour and H100 SXM at $3.99 per hour on its pricing page (read 18 October 2026). A fixed rate comes with a more consistent and managed experience. RunPod also offers per-second billing which eliminates idle costs and can meaningfully reduce total spend on bursty workloads. New users get $5 in free credits when they spend their first $10.

Novita prices by model usage rather than GPU hours. LLM inference starts from around $0.06 per million tokens for smaller models. For teams using existing models rather than training their own, this is often dramatically cheaper than running a dedicated GPU instance because you only pay for actual inference rather than paying for a GPU whether it is busy or not.

The hidden costs to check before you commit

The hourly GPU rate is only part of the picture. Before committing to either RunPod or Vast.ai check the following:

What does object storage cost and is it included? What are the egress fees for moving data out of the platform? RunPod charges no egress fees on its S3 compatible storage. Vast.ai fees vary by host. Check what other products each provider offers and whether they are co-located with your compute. Moving data between platforms adds cost. Also check what regions are available. If you handle personal data from EU users, GDPR requires you to understand where that data is processed and stored. Not all providers have EU infrastructure and even those that do may not offer the data processing agreements you need.

Reliability and security

RunPod operates managed datacenter infrastructure. Check its status page history for past outages. Popular GPUs can be fully allocated during peak demand periods which is worth factoring into your planning.

Check Vast.ai's security page for its current certifications. Verified datacenter hosts deliver consistent uptime. Unverified hosts carry more reliability risk and are better suited to experimental or fault-tolerant workloads than production systems.

Novita operates globally distributed infrastructure with a focus on low latency inference. The platform handles scaling automatically and has real customers in production.

GPU availability

As we covered in our post on the industry-wide GPU shortage, availability is tight across all providers in 2026 due to NVIDIA allocation constraints. Neither RunPod nor Vast.ai is immune to this. Vast.ai's marketplace model means it draws from a broader pool of hosts which can give it an availability advantage when specific GPU types are constrained on a single-provider platform. The practical answer is to maintain accounts on both and check availability across providers when you need to spin up quickly.

Novita sidesteps the availability problem entirely because you are accessing pre-deployed model infrastructure rather than renting your own GPU.

Which one should you use

Use Vast.ai if you are running short experimental jobs, your workload can tolerate occasional interruptions, and you want the lowest possible compute cost. Stick to verified datacenter hosts for anything beyond experimentation.

Use RunPod if you need a consistent managed experience, your workload needs to run reliably for extended periods, or you are moving from prototype to early production. The $5 credit on your first $10 spend makes it easy to test before committing.

Use Novita if you are building a product that needs to call AI models rather than run them. If your use case is inference on existing models like Llama, Stable Diffusion or DeepSeek, Novita's API-first approach is likely significantly cheaper and much simpler to operate than managing your own GPU instances.

The honest answer for most teams is to have accounts on all three. Vast.ai for cost-sensitive experiments, RunPod for production GPU workloads, and Novita for any use case where you are calling an existing model rather than running your own infrastructure.
