Training, inference, rendering, and scientific workloads that require CUDA, ROCm, VRAM, or GPU parallelism should start with GPU servers. Websites, APIs, development environments, scheduled tasks, and lightweight persistent services usually start with VPS options.
A VPS can host the gateway, queue, monitoring, or application layer around a model, but it is not a GPU compute node. A split architecture can use a GPU for inference and a VPS for the public API; the right choice depends on latency, data movement, concurrency, and budget.
If you are unsure, describe the model, concurrency, data size, runtime, and isolation requirements before choosing a product. Do not infer performance from “server,” “private,” or “anonymous” alone.
