About GPUy
GPUy is the developer-first, independent index for cloud GPUs, bare-metal clusters, and serverless token inference. We exist to bring absolute transparency to AI compute pricing, uncover hidden storage and egress traps, and benchmark real hardware performance.
Why GPUy Exists: The Problem with AI Compute in 2026
Marketing figures vs. engineering reality in modern cloud GPU rentals.
Cloud providers advertise low hourly rates (e.g. $1.89/hr for H100 SXM), but bury massive stopped-instance volume storage fees ($0.10–$0.15/GB/mo), $0.05–$0.12/GB network egress taxes, and mandatory minimum billing increments. An instance idle for a weekend can easily double your monthly compute bill.
Not all multi-GPU instances are created equal. Consumer RTX 4090 clouds often wire cards over PCIe Gen 4 x8 with zero peer-to-peer NVLink, causing distributed LLM training (all-reduce) to crawl at 32 GB/s compared to 900 GB/s on genuine SXM5 NVSwitch nodes. We verify real bus topologies before you deploy.
API marketing pages boast “150 tokens/sec” under zero-concurrency warm cache conditions. Under peak multi-tenant production load, Time to First Token (TTFT) degrades to 2.8s and streaming speeds collapse. GPUy runs active latency and throughput telemetry across DeepSeek, Llama, and Qwen endpoints.
Engineers burn dozens of hours configuring SSH keys, discovering that a provider's container root filesystem is ephemeral, running into thermal throttling, or navigating community marketplace host unreliability. GPUy provides battle-tested gotchas so you make the right choice in 30 seconds.
Our 4-Pillar Telemetry & Benchmarking Methodology
How we measure, audit, and normalize GPU cloud data.
We execute direct CUDA memory bandwidth checks, NCCL peer-to-peer all-reduce benchmarks, and 100% sustained FP16/BF16 tensor core stress tests to ensure hardware isn't thermal throttling or running on shared virtualized slices.
Our pricing engine calculates true monthly costs by factoring in stopped instance persistence, container root storage quotas, persistent network volumes, and outbound internet bandwidth charges.
Multi-region probe runners send real token requests to serverless API endpoints to record median Time to First Token (TTFT), median streaming Tokens Per Second (TPS), cold-start latency, and price per 1M input/output tokens.
Every cloud provider profile includes curated, engineer-verified caveats: container vs bare-metal root access, port exposure restrictions, spot preemption warning buffers, and IP reputation status.
Zero Pay-to-Win: How We Maintain Complete Editorial Independence
Rankings Cannot Be Purchased: Cloud providers, datacenter operators, and API aggregators cannot pay to alter their benchmark scores, leaderboards, cost comparison positions, or head-to-head verdicts. Editorial rankings are driven strictly by price, verified hardware specs, and community telemetry.
Affiliate Transparency: Some outbound provider links on GPUy contain referral codes (routed through /go/[slug]). When you register or spin up an instance using our referral links, GPUy may receive a small affiliate commission or compute credits at zero extra cost to you. This revenue directly funds our automated scraper fleet, latency probe nodes, and database servers.
Equal Telemetry Standards: Providers with affiliate programs and providers without affiliate programs are audited under identical benchmark criteria. If a partner provider has poor reliability, high cold starts, or predatory stopped storage fees, we call it out explicitly.
24-Hour Correction SLA: If a provider changes their pricing, adds new datacenters, or fixes a listed gotcha, our team verifies and updates the data within 24 hours of notification.
