CreateOS Sandbox vs Cerebrium
Use Cerebrium to deploy real-time inference, such as LLMs or voice models, as autoscaling GPU endpoints that scale to zero. Use CreateOS Sandbox to run arbitrary agent-generated code in an interactive micro-VM with a shell, a filesystem and egress rules. Cerebrium's unit is a deployed app behind an endpoint; CreateOS's unit is a machine you control.
Pricing at a Glance
CreateOS rates verified 17 October 2026. Cerebrium pricing as published on 17 October 2026. Rates billed per GB rather than per GiB, or as bundled sizes, are quoted as published rather than converted.

Where CreateOS Sandbox Fits Better
What CreateOS Sandbox brings to this matchup, with a plain note on where Cerebrium has the edge.
An interactive environment per task, with exec, files, shell and tunnels, rather than a deployed app behind an endpoint.
Egress rules by host, IP or CIDR; Cerebrium does not publish egress controls.
Fork from a paused sandbox, which Cerebrium does not publish.
Where Cerebrium is strong
Per-second billed GPU serverless with scale to zero, snapshot-based cold starts of 2 to 4 seconds (vendor-stated), native streaming and WebSocket endpoints, and SOC 2 Type II (vendor-stated).
Which to Pick
Pick CreateOS Sandbox if
- You run code an agent writes, not a model you deploy.
- You need a persistent filesystem per session.
- You need to pause and fork sessions.
Pick Cerebrium if
- You serve models in production and need GPUs that scale with traffic.
- You need WebSocket or streaming endpoints for voice AI.
- You want AWS Inferentia2 or Trainium alongside NVIDIA GPUs.
Head-to-Head Comparison
Every dimension side by side, checked on 17 October 2026 against each vendor's own docs and pricing pages. "Not published" means we could not find it on the vendor's pages, not that the feature is missing.
| Dimension | CreateOS Sandbox | Cerebrium |
|---|---|---|
| Built for | Running agent and untrusted code in isolated, disposable Linux sandboxes | Real-time AI inference as autoscaling endpoints |
| GPU | None; no GPU shapes | Yes: B200, H200, H100, RTX PRO 6000, A100, L40S, L4, A10, T4, Inferentia2, Trainium |
| Isolation | Firecracker micro-VM with its own guest kernel | Container (technology not published) |
| Billing | Per second while running: $0.03616363/vCPU-hr, $0.01159025/GiB-hr, storage $0.0001584/GB-hr | Per second plus monthly plan fee |
| Pause and resume | Yes: disk, memory and CPU state saved; vCPU stops billing, memory and storage still bill | Not exposed to users; memory and GPU snapshotting used internally for restores (vendor-stated) |
| Outbound network | Open with no rules; deny-by-default once any host, IP, CIDR or wildcard rule exists, enforced on the host outside the VM | Not published |
| Create by API | Yes: REST API, CLI, MCP server and SDKs for TypeScript, Go, Python, Rust, C# and Java (all but TypeScript pre-1.0) | Python-focused CLI and cerebrium.toml config; apps exposed as REST, streaming or WebSocket endpoints |
Common Questions
Can Cerebrium run arbitrary code an AI agent writes?
It is not designed for that. Cerebrium deploys your Python app as an autoscaling endpoint and documents no interactive per-session environment, egress controls or fork. CreateOS creates a Firecracker micro-VM per task that an agent can exec commands in, write files to and destroy.
How much concurrency does Cerebrium allow?
Hobby allows 500 CPU and 5 GPU concurrency across 3 apps, Standard allows 1,000 CPU and 30 GPU, and Enterprise is unlimited. CreateOS counts concurrent sandboxes instead: 1 on Free, 5 on Beginner, 20 on Pro and 30 on Enterprise.
Is Cerebrium's CPU price lower than CreateOS's?
Yes. Cerebrium charges $0.00000655 per vCPU-second, about $0.02358 per vCPU-hour, against $0.03616363 on CreateOS, and its memory is $0.00000222 per GB-second. Cerebrium's Standard plan adds $100 a month, while CreateOS's Free plan has no plan fee.
