Three families, three tradeoffs
The first decision is: do you rent hardware, or let someone else run the machines? That choice sets your cost structure and your ops burden.
- GPU clouds: rent by the hour, run anything, full control - but you own the images, drivers, autoscaling and shutdown logic
- Managed platforms: push code or a model, get a URL, no machines - at a platform premium and with some limits
- Kubernetes platforms: best control and portability, if you already run Kubernetes
Prices below describe public pay-as-you-go tiers; exact rates move with GPU model, region and promotions, so always check each provider's current pricing page.
The nine options
| Platform | Type | Billing | Learning curve | Best for |
|---|---|---|---|---|
| RunPod | GPU cloud (plus serverless) | Per second/hour | Low | Teams doing fine-tuning and serving |
| Vast.ai | GPU spot marketplace | Per hour, cheapest spot | Medium | Batch and fault-tolerant jobs |
| Lambda Labs | GPU cloud | Per hour, nodes and clusters | Low | Research with one-click PyTorch |
| HF Inference Endpoints | Managed | Per hour with scale-down | Low | Serving models already on the Hub |
| Replicate | Managed | Per prediction | Very low | Solo developers prototyping |
| Modal | Managed, Python-native | Per second, scale to zero | Low | Python teams writing GPU functions |
| RunPod Serverless | Managed GPU | Per second, zero when idle | Medium | Spiky traffic needing autoscale |
| Kubeflow | Kubernetes | Your cluster cost | High | Full ML pipelines on existing K8s |
| KServe | Kubernetes | Your cluster cost | High | Enterprise model serving and canaries |
GPU clouds: control for ops
RunPod bills per second with a large image catalogue; its serverless form handles spiky load. A balanced pick when you want GPUs without a long commitment. Vast.ai is a marketplace of spare cards where spot prices are usually the lowest, but reliability varies - preemption, slow disks, limited bandwidth. Use it for jobs you can re-run, not for online services. Lambda Labs ships preconfigured PyTorch/CUDA images and is a short path to a stable training environment. RunPod Serverless only bills while a container runs; cold starts become the main cost, so it suits sparse, latency-tolerant traffic.
Managed platforms: no machines
HF Inference Endpoints deploys straight from the Hub with autoscaling and monitoring - set scale-to-zero or you pay for idle. Replicate packages models with cog and bills per prediction: easiest for individuals and small traffic, though per-unit cost climbs as volume grows. Modal is Python-native with sub-second-to-second cold starts, ideal for teams that already think in Python functions.
Kubernetes: full control
Kubeflow covers pipelines, notebooks, training and tuning, with many components to maintain. KServe focuses on serving with autoscaling, canary rollouts and multi-framework runtimes - the standard choice when a company already runs Kubernetes.
How to choose
| Your situation | Recommendation |
|---|---|
| Solo dev who needs a working endpoint today | Replicate or Modal |
| Team running fine-tuning plus always-on inference | RunPod, serverless for spikes |
| Existing Kubernetes, standardised serving | KServe, plus Kubeflow for full pipelines |
| Model already on the Hub | HF Inference Endpoints |
| Large re-runnable offline jobs | Vast.ai spot |
Cost reality
- Always-on costs more than you expect: compute 24x30 against the hourly rate before committing.
- Serverless is cheap when idle and expensive at peak: estimate against your real traffic distribution.
- Do not over-provision: a 7B quantised model does not need a top-tier card; 24GB is often enough, and multi-GPU can be slower for small models.
FAQ
Per-prediction or per-hour? Sparse traffic favours per-prediction; sustained load favours per-hour. Multiply daily requests by average duration to see which side you are on.
Is there vendor lock-in? Some. Keep weights and inference code in your own repo and hand only the runtime to the platform.
Buy or rent? Under a few hundred GPU-hours a year, rent. For sustained 24/7 use, owned hardware or reserved instances win - once you add power, noise and depreciation.
How bad are serverless cold starts? It depends on model size and image. Mitigate with warm pools, slim images and fast storage; keep a minimum resident instance for latency-sensitive services.
