AI and Machine Learning PC Builder
Run Llama, Mistral, and Stable Diffusion on your own machine, sized to the models you want.
What's it for?
Budget$1,500
Running AI models at home comes down to one number: how much memory your graphics card has. We spend your budget there first, then size the system memory to match.
Pick the model size you want to run, from 7B up to 70B, and you get a parts list that can actually load it. Every part fits, and each one links to Amazon.
What you get
- The most graphics memory your budget allows, which is what limits model size
- Sized to the models you want to run, from 7B up to 70B
- Plenty of system memory for bigger models and datasets
- Every part checked, so it all fits together

Frequently asked questions
How much VRAM do I need to run local AI models?
As a rough guide, up to 7B models run well on 12GB, 13B to 34B models want 16GB or more, and 70B and larger models need 24GB or more of VRAM (or multiple GPUs). PC Builder AI sets the VRAM floor to your chosen model size.
Does system RAM matter for AI, or just VRAM?
Both matter. VRAM determines what fits on the GPU, while system RAM helps with larger models, offloading, and data handling. Bigger model targets raise both floors.
Can I use the build for training as well as inference?
Yes. The builds prioritize the VRAM and memory that both training and inference need. For heavy training you generally want the most VRAM your budget allows.
