Graphsignal
FreemiumProduction GPU profiler for tuning AI inference workloads
What is Graphsignal?
Graphsignal profiles GPU and accelerator workloads in production so teams can find what slows down model inference. It targets engineers running engines such as vLLM, SGLang and TensorRT on NVIDIA or AMD hardware, and it feeds findings to AI agents that suggest fixes.
The idea is to optimize from what production actually did instead of a local benchmark. An agent reads data through a Signals API, spots problems like a jump in time to first token after a deploy, and changes flags or code to fix them.
Pricing is by profiled GPU hour. A free plan covers 100 hours a month for one user, and the Pro plan bills per hour with unlimited users and 30 days of retention.
