Provider Overview
Strengths & Best For
Modal is a serverless GPU cloud that lets Python developers run H100, A100, and T4 workloads with a simple decorator-based API and zero infrastructure management — cold starts measured in seconds. Per-second billing means you only pay for actual compute time, making it highly cost-efficient for bursty AI inference, LLM serving, and batch ML jobs. The go-to on-demand GPU cloud for ML engineers who want to ship fast without touching DevOps.
- Zero infra management
- Instant cold starts
- Python-native API
- Per-second billing
Hot Aisle provides bare-metal H100, A100, and RTX GPU servers with no virtualization overhead and dedicated hardware for AI training and HPC workloads, based in the UK. Monthly and on-demand billing options are available for teams that need consistent, dedicated GPU performance without shared-tenancy concerns. A strong bare-metal GPU option for UK-based HPC teams and AI labs that need maximum hardware performance and full control over their compute environment.
