Lowest Cost Tier

Spot GPU Instances:
Up to 50% Off NVIDIA GPUs.

Run batch jobs, training experiments, and non-urgent workloads on discounted spot instances. Same NVIDIA GPUs, same performance, lower price. Instances can be terminated when demand spikes.

How Spot Instances Work

Idle Capacity

GPUs not currently booked on dedicated instances become available as spot capacity at a significantly discounted rate.

You Deploy

Launch a spot instance just like a dedicated one. Same configuration, same GPU, lower price.

You Run Your Job

Your workload runs at full performance. No throttling. Checkpoint regularly for fault tolerance.

Termination

If capacity is reclaimed, your spot instance is terminated. Checkpoint regularly so you can resume from where you left off.

Built for These Workloads

Any workload that can tolerate interruption is a candidate for spot pricing. Checkpoint your work, and restarts are painless.

Hyperparameter Tuning

Run hundreds of short experiments at a fraction of the cost. Each run is independent, so interruptions only affect one trial.

Data Preprocessing

ETL pipelines and dataset transformations that can be restarted from the last checkpoint. Perfect for spot pricing.

Model Evaluation

Run inference benchmarks and validation passes on cheaper hardware. Results don't change based on instance type.

Research and Prototyping

Explore architectures and ideas without worrying about burning through your GPU budget. Iterate fast, spend less.

Hybrid Strategy

Mix Spot and Dedicated

Run your critical training loop on a dedicated instance (99.99% SLA) while offloading evaluation jobs to spot. Both are on-demand tiers, so you can mix them across your pipeline to optimize cost without sacrificing reliability where it matters.

  • Critical training on dedicated instances with 99.99% SLA

  • Evaluation and validation on discounted spot instances

  • Data preprocessing on spot for cost-efficient pipelines

FAQ / 05

Spot Instance FAQ

How spot capacity is priced and reclaimed, and when it is the right call.

Spot instances let you rent GPUs at a discount by using idle capacity in our data center network. They run on the same hardware as dedicated instances but cost up to 50% less. Both spot and dedicated are on-demand tiers with per-minute billing. The tradeoff: spot instances can be terminated when demand for that GPU model increases, whereas dedicated instances carry a 99.99% SLA.

Savings vary by GPU model and current demand. Typical discounts range from 20% to 50% off the dedicated rate. Check the pricing page for current spot rates on each GPU model.

Spot instances can be terminated when demand for that capacity is reclaimed. There is no grace period, so design your pipeline with regular checkpointing. Save progress frequently, and restarts pick up from the last checkpoint.

Any workload that handles interruption gracefully: hyperparameter searches, data preprocessing, model evaluation, batch inference, and research experiments. If you can checkpoint and restart, you can save money with spot.

Yes. Both are on-demand tiers, so you can mix them freely. Many teams run critical training jobs on dedicated instances (99.99% SLA) while offloading evaluation, preprocessing, and experimental runs to spot. This hybrid approach gives you reliability where it counts and savings everywhere else.

Same GPUs. Same data centers. Same performance. If your workload can tolerate interruption, there's no reason to pay full price.
