They released a bunch of different sized models and there are already quantized versions showing up on HF.

https://huggingface.co/unsloth/DeepSeek-R1-Distill-Llama-8B-... for example has versions that are 3GB, 4GB, 5GB, 8GB and 16GB.

That 3GB one might work on a CPU machine with 4GB of RAM.

To get good performance you'll want a GPU with that much free VRAM, or an Apple Silicon machine with that much RAM.
