Which Cloud GPUs Provide the Strongest Price-Performance Balance for AI Inference?

The strongest price-performance balance for AI inference isn't about finding the cheapest GPU or the fastest one. It's about matching the right cloud GPU to your specific inference workload: model size, concurrency, latency requirements, and budget.

From GMI Cloud's experience provisioning H100 and H200 clusters for production inference, teams that start with their workload profile and work backward to GPU selection consistently achieve better cost-per-inference outcomes than those who default to the most popular (or cheapest) option.

The GPU cloud landscape in 2026 includes hyperscalers, specialized AI cloud providers, GPU marketplaces, and managed inference platforms.

This article profiles 12 platforms, establishes the evaluation criteria that matter for inference price-performance, details GMI Cloud's GPU product capabilities, and provides a scenario-based selection guide. If you need help with GPU capacity planning, GMI Cloud's team can assist at gmicloud.ai.

What Makes a GPU Cloud Platform Good for Inference

Modern GPU Access

H100 and H200 GPUs deliver the memory bandwidth (3.35-4.8 TB/s) and FP8 compute (1,979 TFLOPS) that production LLM inference demands. Platforms still running primarily on A100 or T4 GPUs can't match the throughput per dollar that current-gen hardware provides.

Check whether the platform offers SXM variants (higher bandwidth than PCIe) and multi-GPU configurations with NVLink.

Fast Provisioning and Auto-Scaling

GPU instances should spin up in minutes, not hours. Auto-scaling should respond to traffic changes within 2-5 minutes. If the platform requires manual capacity requests or has multi-hour provisioning times, it can't support production inference with variable traffic patterns.

Pre-Configured Serving Stack

Platforms that ship with vLLM, TensorRT-LLM, and Triton pre-installed and tuned for the GPU type save weeks of setup time. If you have to install CUDA drivers, compile TensorRT-LLM from source, and tune NCCL settings yourself, that's engineering cost on top of GPU cost.

Transparent Pricing

Per-GPU-hour pricing should be visible without a sales call. Per-token pricing for model APIs should be listed per model. Hidden costs (egress fees, storage charges, minimum commitments) erode price-performance comparisons.

Low Lock-in Risk

OpenAI-compatible APIs and standard container formats (Docker, OCI) let you move between providers. Proprietary SDKs, custom container formats, and provider-specific monitoring tools create migration costs that effectively raise your per-inference price.

GMI Cloud: GPU Infrastructure for Production Inference

Service Positioning

GMI Cloud (gmicloud.ai) provides GPU cloud infrastructure for both enterprises and individual developers, built on owned NVIDIA H100 SXM and H200 SXM clusters.

It's branded "Inference Engine" because it combines GPU infrastructure with a 100+ model library, but the GPU layer is available for any inference workload, including custom models deployed via the Deploy feature.

GPU Types and Pricing

H100 SXM

• VRAM: 80 GB HBM3
• Memory BW: 3.35 TB/s
• Price: ~$2.10/GPU-hr
• Best For: General production inference, 7B-70B models

H200 SXM

• VRAM: 141 GB HBM3e
• Memory BW: 4.8 TB/s
• Price: ~$2.50/GPU-hr
• Best For: Large-model inference (70B+ FP16 on single GPU), bandwidth-critical workloads

Nodes run 8 GPUs with NVLink 4.0 (900 GB/s bidirectional aggregate per GPU on HGX/DGX platforms) and 3.2 Tbps InfiniBand inter-node. Check gmicloud.ai/pricing for current rates.

Price-Performance Advantages

Scenario matching: GMI Cloud's team helps match GPU type to workload. A 7B model doesn't need an H200; an H100 handles it with headroom. A 70B FP16 model fits on a single H200 (141 GB) instead of requiring 2x H100 (160 GB), cutting GPU cost by roughly 40%.

Model API cost efficiency: for teams that prefer API access, the Model Library offers GLM-5 (by Zhipu AI) at $1.00/M input and $3.20/M output (68% cheaper than GPT-5 at $10.00/M), and GLM-4.7-Flash at $0.07/M input and $0.40/M output (33% cheaper than GPT-4o-mini at $0.60/M). All pricing from console.gmicloud.ai.

Pre-optimized stack: CUDA 12.x, vLLM, TensorRT-LLM, and Triton come pre-configured. You don't pay for the 2-4 weeks of engineering time that manual setup typically requires on bare GPU instances.

Customer Application

A media company running multimodal content generation (LLM for copywriting, Wan 2.6 for video at $0.15/request, GLM-Image for thumbnails at $0.01/request) consolidated from three separate GPU providers to GMI Cloud.

Result: 45% reduction in total GPU spend, single API for all models, and unified monitoring across workloads. The key was right-sizing GPU allocation per workload type instead of running everything on the same instance configuration.

Selection Guide: GPU Platform by Inference Scenario

Scenario (Priority / Recommended Platforms)

• Small-scale real-time inference (7B models, <10K req/day) — Priority: Low cost, fast setup — Recommended Platforms: RunPod, Replicate, GMI Cloud (Playground/API)
• Large-scale batch inference (document processing, labeling) — Priority: Max throughput/dollar — Recommended Platforms: GMI Cloud (Batch mode), Vast.ai, Lambda
• High-concurrency production API (100K+ req/day) — Priority: Auto-scaling, P99 SLA — Recommended Platforms: GMI Cloud (Deploy), CoreWeave, AWS SageMaker
• Multi-model/multimodal serving — Priority: Unified API, model breadth — Recommended Platforms: GMI Cloud (100+ models), Together AI
• Enterprise with compliance needs — Priority: Dedicated infra, SOC 2 — Recommended Platforms: AWS, Azure, GMI Cloud
• Budget experimentation — Priority: Lowest possible cost — Recommended Platforms: Vast.ai, RunPod (community tier)
• DevOps-integrated GPU deployment — Priority: CI/CD, K8s native — Recommended Platforms: Northflank, CoreWeave

Conclusion

The GPU cloud landscape in 2026 offers more options than ever, which makes the selection decision harder, not easier. Price-performance balance isn't a property of the GPU itself; it's a property of how well the GPU matches your inference workload. An H200 is overkill for a 7B model.

An RTX 4090 is underpowered for a 70B model at production concurrency. The platform matters as much as the hardware: pre-configured serving stacks, auto-scaling, and transparent pricing are what turn raw GPU performance into actual cost-per-inference savings.

FAQ

Q: Is H100 or H200 better for inference price-performance?

It depends on your model size. H100 (80 GB, ~$2.10/GPU-hr) is more cost-efficient for models that fit in 80 GB VRAM (7B-32B in FP16, up to 70B in FP8). H200 (141 GB, ~$2.50/GPU-hr) is better for 70B+ FP16 models because it avoids the cost of multi-GPU setups.

The 19% price premium for H200 is worth it when it eliminates a second GPU entirely.

Q: Should I use GPU marketplace pricing (Vast.ai) for production inference?

For production workloads with SLA requirements, marketplace pricing is risky. Variable availability, inconsistent hardware, and no guaranteed uptime make it unsuitable for user-facing APIs. It's excellent for batch processing, experimentation, and workloads where occasional downtime is acceptable.

Q: How do model API costs compare to raw GPU costs?

At low volume, model APIs are cheaper (no idle GPU cost). At high volume, dedicated GPUs win. The crossover depends on utilization: if you can maintain 60%+ GPU utilization, dedicated instances typically cost less per inference than per-token API pricing.

GMI Cloud offers both options: GPU instances for self-managed serving, and Model Library API (GLM-5 at $3.20/M output) for managed access.

Q: What's the most important GPU spec for inference?

Memory bandwidth, not compute TFLOPS. Token generation is memory-bandwidth-bound: the GPU reads model weights from VRAM for every output token. H200's 4.8 TB/s versus H100's 3.35 TB/s means faster token generation at the same FP8 compute.

VRAM is the gating factor for which models you can run; bandwidth determines how fast you run them.
