FluidStack

FluidStack GPU pricing overview

FluidStack is a specialist GPU cloud provider headquartered in London, UK. FluidStack aggregates H100, A100, and consumer GPU capacity from data centers across the US and EU, offering competitive bulk pricing and flexible contracts for AI training and LLM fine-tuning workloads. Spot GPU rental is available alongside on-demand and reserved options, making it a cost-effective choice for teams with variable compute needs. A strong pick for EU-based teams wanting broad GPU availability without committing to a single provider. Billing is On-demand, Spot, Reserved with a minimum commitment of None. Available regions include US-East, US-West, EU-West, EU-Central. On-demand GPU instances can be provisioned in minutes with no upfront cost, making FluidStack suitable for both short-duration experiments and sustained production workloads.

FluidStack vs other GPU providers

FluidStack competes with providers including Lambda Labs, CoreWeave, RunPod, Paperspace, Vast.ai, and the major hyperscalers (AWS, Google Cloud, Azure) for GPU compute workloads spanning LLM training, fine-tuning, and inference serving. Key differentiators include: Competitive pricing; EU/US coverage; Spot availability.

Best use cases for FluidStack

FluidStack is best suited for: Cost-sensitive training, EU-based teams, Flexible workloads. Support tiers range from Standard → Enterprise, making it viable for both individual researchers and enterprise teams with SLA requirements. There are currently 17 active GPU listings on FluidStack, covering H100 80GB, A100 80GB, A100 40GB, RTX 4090 and more. For workloads requiring the highest single-GPU throughput, H100 SXM5 instances with NVLink interconnect deliver the best performance per dollar at scale. For cost-sensitive fine-tuning or inference of models up to 13B parameters, A100 40GB or RTX 4090 instances typically offer the best value.

FluidStack billing model and cost structure

FluidStack uses On-demand, Spot, Reserved pricing. On-demand instances are billed per second or per hour depending on the instance type, with no termination fees. Spot (interruptible) instances are available from $0.10/hr — typically 40–70% cheaper than on-demand rates, suitable for fault-tolerant training jobs with checkpointing. Reserved instance pricing, where available, can reduce costs by 30–60% for predictable long-running workloads. Always compare the effective hourly rate including egress, storage, and networking costs when evaluating total cost of ownership across providers.

Choosing the right GPU on FluidStack

GPU selection depends on model size, precision, and whether your workload is compute-bound or memory-bandwidth-bound. For LLM training above 30B parameters, H100 80GB SXM5 instances with NVLink are the standard choice — the 3,350 GB/s HBM3 bandwidth and 989 TFLOPS FP16 throughput make them 2–2.5× faster than A100 for transformer workloads. For inference of 7B–13B models in FP16 or BF16, A100 40GB offers the best cost-per-token on most providers. RTX 4090 instances are ideal for fine-tuning, prototyping, and quantized inference (INT4/INT8) of models up to 70B. Read the H100 vs A100 guide or the GPU benchmarks for ML guide for a full breakdown.

How FluidStack pricing data is collected

Prices shown are sourced from FluidStack's public pricing API or pricing page and refreshed every 15 minutes. On-demand rates reflect the current list price for a single GPU instance in the cheapest available region. Spot prices, where available, reflect interruptible instance rates at the time of the last snapshot. All prices are in USD per hour. Daily snapshots are retained for 90 days and visualised in the GPU price history charts — useful for identifying seasonal pricing patterns and evaluating whether current rates are above or below the 30-day average.
