Saturn Cloud: cost, fit and limits
Saturn Cloud is a data science and GPU compute platform made by Saturn Cloud, Inc that runs Jupyter notebooks, deployments, fine-tuning and dedicated inference endpoints for open models, either hosted on AWS or inside a customer's own Kubernetes cluster.
What to know first
Saturn Cloud's homepage now puts dedicated GPU inference first, and the notebook workspace is described more briefly than before. The hosted Free account is for getting familiar with the platform. Hosted Pro is pay as you go, billed per hour, and large GPU capacity is quoted per deal. The security page shows a SOC 2 Type 1 audit, while the privacy policy still names EU-US Privacy Shield. The pages read do not say whether customer data trains models.

Who Saturn Cloud is best for
Teams serving open models
Dedicated endpoints for open models are profiled for the customer's own traffic, with a throughput and latency target once profiled. That suits teams that already know which model they want to run.
Organizations that must keep data in their own cloud
Because the platform only needs a Kubernetes cluster, it can be deployed in the customer's AWS account, on-premises or air-gapped, which helps when hosted notebooks are not allowed.
Data scientists who need occasional GPU hours
Hosted Pro has no reservation: an H100 on demand is listed at $2.95 per hour, so short experiments do not require a contract.
Saturn Cloud plans and pricing
| Plan | Price | What it includes |
|---|---|---|
| Hosted Free | Free account, no price listed on the plan page | Free access to the platform so a team can get familiar with it before upgrading to the Pro plan. |
| Hosted Pro (pay as you go) | $0.09 per hour for Large (4 vCPU, 16 GB); $0.40 per hour for 2XLarge; $2.95 per hour for 1xH100; storage $0.10 per GB per month | On-demand instances billed per hour used with no commitment. The first charge is $5 of credit, then the card is charged each time $10 of usage accrues. |
| Dedicated GPU capacity | Custom quote; reference prices from $1.10 per GPU-hour (NVIDIA L40S) to $6.65 (NVIDIA B300) | Private GPU capacity from neocloud partners, a dedicated endpoint, model profiling on that hardware and a contracted performance target. GB300 NVL72 is priced per deal. |

What Saturn Cloud does
- Jupyter notebooks and deployments
- Notebooks and deployments run inside the Saturn Cloud application and are reached through its own authentication proxy, according to the security page. This is the workspace side of the product.
- Dedicated inference endpoints
- Each endpoint for an open model is tuned for the customer's traffic and carries a throughput and latency SLA once profiled. The model catalog names Kimi K3, GLM-5.3, DeepSeek V4 Flash and gpt-oss-120b.
- Fine-tuning
- Models that support it can be fine-tuned on the customer's own data and then served from the same dedicated endpoint, so training and serving stay in one place.
- Bring your own model
- Besides the catalog, a customer can bring a model of its own to the dedicated endpoint, which is then profiled on the chosen GPU hardware before the performance target is set.
- Own-cloud deployment
- The platform needs only a Kubernetes cluster, so it can run in the customer's AWS account, on-premises or air-gapped. Pod volumes are encrypted with AWS KMS and a nightly application backup is preconfigured.
How Saturn Cloud handles your data
The pages read do not state whether Saturn Cloud trains on customer data. The hosted service runs exclusively on AWS according to the security page, which names no region, and enterprise installs can sit in the customer's own AWS environment in a location the customer chooses. The security page shows a SOC 2 Type 1 audit covering security, availability and confidentiality. The privacy policy says data is kept as long as needed to provide the service, as users instruct or as law requires, with no fixed period, and deletion requests go to support@saturncloud.io. The policy still describes EU-US Privacy Shield as its transfer basis.
Where Saturn Cloud falls short in practice
- GPU capacity is mostly sales-led. The homepage says self-service has limited GPU availability and asks for contact with sales for more. Hosted Pro lists 1xH100 with a minimum three-month term at Contact us, not an hourly price.
- Notebook side is thinly described. The pricing page is built around GPU capacity for inference endpoints, and no per-seat price for a workspace seat was found. Teams buying mainly for collaboration should ask before assuming it.
- Transfer basis looks outdated. The privacy policy still relies on EU-US Privacy Shield, which a European buyer should raise with the vendor before sending personal data through the service.

Alternatives to Saturn Cloud
Saturn Cloud: common questions
Is Saturn Cloud still a notebook platform?
Saturn Cloud still runs Jupyter notebooks and deployments, but its homepage now emphasizes dedicated GPU inference for open models. The notebook side is described more briefly, so check the current plan details with the vendor if notebooks are your main reason to buy.
How is Saturn Cloud Hosted Pro billed?
Hosted Pro is pay as you go, billed per hour of resources used and charged to the card on file. The first charge is $5 of credit, and the card is charged again each time $10 of usage accrues. A Large instance is listed at $0.09 per hour as of November 2026.
Can Saturn Cloud run inside my own cloud account?
Yes. The platform needs only a Kubernetes cluster, so enterprise deployments can run in the customer's own AWS environment, on-premises or air-gapped. The security page notes encrypted pod volumes using AWS KMS and a nightly application backup preconfigured for every deployment.
What does Saturn Cloud's privacy policy say about data transfers?
The privacy policy still describes EU-US Privacy Shield as its transfer basis, as found in November 2026. The pages read did not give a fixed retention period or say whether customer data trains models, so ask the vendor for both in writing.
What does dedicated GPU capacity cost on Saturn Cloud?
Dedicated capacity is a custom quote. The page lists reference prices per GPU-hour from $1.10 for an NVIDIA L40S to $6.65 for a B300, and states that these are reference points only. GB300 NVL72 capacity is priced per deal, with no figure published.
