Yes, but it’s a bit more than that. All models are produced using a process known as neural network quantization, which optimizes them to be able to run on a CPU. This, plus appropriate backend code written in C, means GPT4All is quite efficient and needs only 4-8GB of RAM (depending on the model) and a CPU with AVX/AVX2 support.

GPT4all, it’s open source and you can run it on your own machine.
How is this able to run without a gpu? Is it that the models are small enough so that only a cpu is needed?
