GPU Cost Optimization: How to Reduce Costs with GPU Sharing and Automation

The escalating costs of GPUs are becoming a significant concern for businesses, as they are now widely used beyond AI-focused companies for various workloads like machine learning and analytics. High expenses are often due to GPUs being underutilized, with instances such as the NVIDIA H100 on AWS costing around $5,000 monthly even when idle. Techniques like GPU time-slicing and Multi-Instance GPU (MIG) offer solutions by allowing multiple workloads to share a single GPU more efficiently, drastically reducing costs. Cast AI has integrated these techniques into its Kubernetes management platform, automating GPU sharing to optimize resource allocation and significantly cut expenses. Additionally, by leveraging Spot Instances, the platform can further reduce GPU-related costs by up to 93% per developer, balancing cost efficiency with performance needs.
