CVReviewed by Challenging Voice Editorial · Updated Aug 2026How we rate ↗
GPUX is a serverless GPU inference platform for running AI models in the cloud without managing infrastructure: it supports models including StableDiffusionXL, ESRGAN, and Whisper alongside custom LLMs, with a 1-second cold start for rapid model initialization and ReadWrite Volumes for persistent data across inference runs.
The 1-second cold start is the detail that actually matters for a serverless GPU product – traditional serverless inference often carries a multi-second-to-minutes cold-start penalty when a GPU instance has to spin up from idle, which makes serverless pricing attractive on paper but impractical for latency-sensitive use cases. GPUX also lets organizations with a private trained model sell inference requests against it to other organizations, turning a proprietary model into a monetizable API rather than an internal-only asset.
GPUX reports making StableDiffusionXL 50% faster on RTX 4090 hardware, with cost reductions of 50-90% over always-on GPU infrastructure. Pricing starts as low as $0.2/hour, targeting developers and organizations running AI inference workloads without dedicated infrastructure teams.
