9 Best Serverless GPU Providers for LLM Inference (2026)

Serverless GPU services offer a flexible and cost-effective solution for machine learning inference, but their practical implementation presents challenges such as varying cold start latencies, complex pricing structures, and potential compliance issues. The guide compares nine providers, including RunPod, Modal, and Replicate, highlighting key features like cold start times, pricing, and best use cases. It notes that while serverless GPUs are ideal for rapid prototyping and workloads with variable traffic, they may not be suitable for sustained high utilization or latency-sensitive applications. Compliance with regulations such as HIPAA and GDPR is another concern, as shared infrastructure can pose data sovereignty issues. To optimize costs, strategies like right-sizing GPUs, using warm pools, and batching requests are recommended, especially for teams with substantial monthly expenses on inference. Ultimately, the decision between serverless and dedicated GPU infrastructure depends on specific workload requirements, compliance needs, and cost considerations.
