In short
Modal: A serverless platform for running Python functions, web endpoints, batch jobs and sandboxes on CPUs and GPUs.
Klio Compute: serverless GPUs for Python. Run a function on a GPU with one decorator, deploy endpoints, task queues, schedules and sandboxes, or put an open model behind an OpenAI-compatible API, and pay per second from prepaid credit.
Where Modal is the better choice
- More of its own platform features: Klio Compute's Modal-compatible API doesn't offer
@modal.clustered,@modal.batched,@modal.web_server,@modal.wsgi_app,.remote_gen(),CloudBucketMount,region=orcloud=. - Multi-node training is in private beta, beyond the 8 GPUs one container can have on either platform.
- Its Starter plan includes $30 of free credit every month, and region selection.
- T4 GPUs, which Klio Compute doesn't list.
Where Klio Compute differs
- Modal code runs with one changed import line, and
klio migrate --checkreports what works before you change anything. - Prepaid credit: work stops at zero instead of running up an invoice, and a monthly purchase limit caps what can be spent.
klio model deployputs an open model behind an OpenAI-compatible API on your own address in one command.- GPU prices follow the market and are shown live; a running container keeps the price it started at.
Features
| Feature | Klio Compute | Modal |
|---|---|---|
| Serverless GPU functions or containers | Yes. Functions, endpoints, task queues and schedules on a GPU from one decorator. (docs) | Yes. (source) |
| Scale to zero | Yes. Endpoints and models stop when idle and start on the next request. (docs) | Yes. Containers spin down when idle; min_containers keeps some warm. (source) |
| Billing per second or finer | Yes. Metered per second. (docs) | Yes. Listed per second. (source) |
| Several GPUs in one container | Yes. 1, 2, 4 or 8 GPUs of one type; more than one needs a paid workspace. (docs) | Yes. Up to 8 GPUs on most types, up to 4 on A10. (source) |
| Sandboxes | Yes. Create, run commands and code, read and write files. (docs) | Yes. (source) |
| Volumes | Yes. Named volumes mounted into any container. (docs) | Yes. (source) |
| OpenAI-compatible model serving | Yes. klio model deploy, for the models klio model list shows. (docs) | Partly. An example you deploy as your own code runs vLLM in OpenAI-compatible mode. (source) |
| Runs Modal code with an import change | Yes. import klio_compute.compat as modal; a few features are refused with a clear message. (docs) | Yes. It is Modal. (source) |
| Prepaid credit | Yes. Top up, set a monthly purchase limit; work stops at zero. (docs) | No. Workspaces are billed monthly, with early charges at usage thresholds. (source) |
GPU prices per hour
Public list prices verified 8 November 2026 from Modal's pricing page. Klio Compute's prices are live, checked Nov 8, 08:50 UTC. GPU prices follow the market and are checked every few minutes. A running container keeps the price it started at.
