Utilyze is an open-source GPU monitoring tool that measures actual compute efficiency — the percentage of theoretical maximum floating-point throughput and memory bandwidth your workload is achieving. The core problem: standard GPU dashboards can read 100% utilization while your actual compute SOL (Speed of Light) percentage sits at 1%, creating dangerous false confidence. The tool tracks three metrics in real time: Compute SOL% (actual FLOPS vs theoretical max), Memory SOL% (achieved bandwidth vs peak capacity), and Attainable SOL% (the realistic ceiling given your workload's arithmetic intensity). This lets ML engineers immediately identify whether they're compute-bound or memory-bandwidth-bound and pull the right optimization levers. Built by Systalyze and released under Apache 2.0, Utilyze currently targets NVIDIA hardware with AMD MI300X/MI325X support planned. For any team spending real money on GPU compute for AI training or inference, this kind of visibility can cut cloud costs significantly — and it runs with negligible overhead, meaning you can monitor in production without affecting workload performance.

Reviewer scorecard

Builder

Perfect for prototyping. I described a dashboard and had a working app in 3 minutes. Not production-ready, but unbeatable for speed-to-demo.

This belongs in every MLOps toolkit immediately. Standard utilization metrics are dangerously misleading — I've seen teams burn thousands on H100s that were memory-bandwidth-bottlenecked at 3% actual compute SOL. Apache 2.0 means you can embed it in any monitoring stack without licensing headaches.

Skeptic

Impressive demo, but the generated code is messy and you'll rewrite most of it. If you can't code, you can't fix what it breaks. Know what you're getting into.

NVIDIA-only for now limits the audience significantly, and 'attainable SOL' calculations depend on workload-pattern assumptions that may not hold for your specific model architecture. AMD MI300X support is 'planned' — which could mean months away. Check back when multi-vendor support lands.

Creator

As a creator who needs quick landing pages and MVPs, this is a game-changer. I built a waitlist page with email capture in under 5 minutes.

Even running local Stable Diffusion or ComfyUI, knowing exactly why your 4090 is bottlenecked is genuinely useful. Negligible overhead means you can leave it running during actual generation and get real performance data without sacrificing throughput.

As inference costs become the dominant AI expense line, compute visibility tools become critical infrastructure. Teams that can squeeze 30% more throughput from the same GPU cluster win on margins. Utilyze is foundational to the efficiency war that's just beginning.
