GPU Cloud Computing in 2026
GPU cloud is renting NVIDIA (and now AMD) hardware by the hour instead of buying it. It is the default way teams train and serve models in 2026.
The main providers
- RunPod - from 0.34 USD/hr (RTX 3090), serverless GPU option
- Vast.ai - marketplace of spare GPUs, cheapest, from 0.25 USD/hr
- Lambda Labs - dedicated clusters, A100 from 1.29 USD/hr
- CoreWeave - enterprise scale, Kubernetes-native
- AWS / GCP / Azure - the hyperscalers, most reliable, priciest
- Together / Fireworks / Baseten - managed inference, pay per token
Pricing models explained
- On-demand per hour: flexible, expensive for long runs
- Spot / interruptible: 60-80% cheaper, can be killed anytime
- Reserved (1-3 yr): 40-60% off, for steady workloads
- Serverless GPU: pay per second, scale to zero, cold starts
- Pay per token: managed inference, zero infra
Cost traps to avoid
- Idle GPU: paying for a box that finished 3 hours ago - always set auto-shutdown
- Data transfer fees: egress can exceed compute on big datasets
- Over-provisioning: a 7B model does not need an H100 - a 24 GB card is enough
- Multi-GPU for small models: parallelism overhead can slow you down
Example budget
Fine-tuning a 7B with LoRA: ~2-4 GPU-hours on a 24 GB card = roughly 1-3 USD. Serving 24/7 on a 3090: 250-350 USD/month.
FAQ
Which provider is cheapest? Vast.ai spot, but reliability varies; RunPod is the balanced choice. Do I need GPU cloud for everything? No - small models and embeddings run fine on CPU or serverless CPU.
