VPS for AI and ML

AI and ML workloads range from light CPU inference to GPU-heavy tasks, so the right VPS depends heavily on the model and how you run it.

Machine learning splits broadly into training and inference, and their needs differ sharply. Training large models demands powerful GPUs, lots of memory, and fast storage, while running inference on smaller or quantized models can work on a CPU with enough RAM. Memory is often the binding constraint, since a model must fit in RAM or GPU memory to run at all.

When choosing a plan, decide first whether your workload needs a GPU; many hosts offer GPU instances for heavier tasks, while CPU-only VPS suit smaller models and lighter inference. Size RAM to your model plus overhead, and use fast NVMe storage for datasets and model weights. A common pitfall is trying to run a large model on a CPU-only plan without enough memory, which leads to swapping or outright failure, so match the plan to the model's footprint.

Frequently asked questions

Do I need a GPU for AI on a VPS?

It depends; training large models and high-throughput inference benefit from a GPU, but smaller or quantized models can run acceptably on a CPU with enough RAM.

How much RAM do AI workloads need?

Enough to hold the model plus working data; small models may fit in 8-16 GB, while larger ones need much more, and GPU tasks are limited by GPU memory instead.

Can I run inference on a CPU-only VPS?

Yes, for smaller models and modest request volumes CPU inference is practical, especially with optimized or quantized models, though it is slower than GPU inference.
