Run SGLang on a cloud GPU, in 30 seconds
High-throughput serving with RadixAttention — excels at structured and agentic workloads. SGLang pairs RadixAttention prefix caching with a structured-generation frontend, which makes it the fastest server for agentic and JSON-heavy workloads where many requests share prompts. Same OpenAI-style API as vLLM, often higher throughput on multi-turn traffic. From $0.159/hr on an interruptible RTX 5090.
Template is free
You pay the GPU price only: SGLang on a RTX 5090 is $0.318/hr on-demand, $0.159/hr interruptible, billed per second.
Volumes for state
Models, datasets and outputs live on a $0.08/GB/mo volume; the instance stays disposable.
Private by default
Dedicated GPU, encrypted disk, crypto payments, no KYC, no stored IPs — Jupyter and SSH behind your own credentials.
Best GPUs for SGLang
Three price points that run this template well — Good, Better, Best. Every model in the catalogue works; these are the value picks.
| Tier | GPU | VRAM | On-demand | Interruptible | Why this card | Action |
|---|---|---|---|---|---|---|
| Good | RTX 5090 | 32 GB | $0.318 | $0.159 | Cheap, fast card for 7B–14B agent backends. | Deploy |
| Better | L40S | 48 GB | $0.466 | $0.233 | 48 GB for 32B-class models with long shared prefixes. | Deploy |
| Best | H100 SXM | 80 GB | $1.587 | $0.793 | Multi-GPU tensor parallel for 70B+ agent fleets. | Deploy |

Deploy SGLang from the console, CLI or API
Pick the template in the console deploy bar, or script it:
- Console — filter by GPU, choose SGLang in the template picker, set disk and env, deploy.
- CLI — pip install powergpu, then the command on the right. CLI reference.
- API — POST /v1/instances with "template": "sglang". REST reference.
- Own image — any OCI reference works too; we inject the NVIDIA runtime. Template docs.

SGLang on a cloud GPU: FAQ
Environment variables, ports and custom images are covered in the template docs.
How much does it cost to run SGLang on a cloud GPU?
Only the GPU price — the template is free. From $0.159/hr on an interruptible RTX 5090, $0.318/hr on-demand on a RTX 5090. Billing is per second, so an hour of tinkering costs an hour, not a day. Storage is $0.08/GB/month.
How long does SGLang take to start?
About 30 seconds from the deploy click: the image is pre-cached on hosts, ports are mapped and TLS is terminated for you. Restarting a stopped instance is faster, and your disk is exactly as you left it.
Can I keep my models and outputs between sessions?
Yes — attach a volume at deploy. Everything on the volume survives instance destruction and mounts on the next instance in the region in seconds, at $0.08/GB/month. The instance disk itself survives stop/start but not destroy.
When is SGLang faster than vLLM?
On workloads with heavy prompt reuse — agents, RAG with fixed system prompts, batch structured extraction — RadixAttention skips recomputation of shared prefixes and can double effective throughput.
