Launch HN: Expanse (YC P26) – Unlock Wasted GPU Capacity

Hacker News · 4 months ago · 29

Expanse uses deep learning models that analyze source code, submission scripts, and hardware telemetry to predict actual GPU and compute resource needs before jobs run on HPC clusters, addressing the problem that datacenters waste 59% of compute due to users over-requesting resources by 2-3x to avoid job failures. The company measured a national-scale HPC cluster and found roughly $8.5 million in wasted compute monthly, and their multimodal predictor outperforms frontier LLMs by 8x on resource prediction tasks. Customers can recover wasted capacity and reduce over-provisioning, with Expanse offering paid pilot deployments starting with a two-week measurement window.
