Running AI answers on a CPU instead of a GPU.
CPU inference is like making pancakes in one frying pan. Fine for breakfast, not for a school cafeteria.
Use it for small local models and light traffic. It saves money, but do not expect speed.
Inference
CPU inference is still inference. It just uses the CPU for the math.
GPU
CPU inference can avoid using a GPU. It is usually slower.
Quantization
Quantization shrinks the model. That helps a CPU run it.
Llama.cpp
Llama.cpp is often used for local CPU runs.
