Hardware FAQ
Do I need a GPU for local AI?
Not necessarily. Modern CPUs can run smaller models (3B-8B) effectively. However, a GPU provides 2-5x speed improvements and enables running larger models more efficiently. If you plan to use AI regularly or work with larger models, a GPU is highly recommended.
How much RAM do I really need?
RAM is crucial for local AI. As a rule of thumb: model size + 4-8GB for the operating system. For an 8B model (~5GB), you need at least 12GB RAM, but 16GB+ is recommended for smooth operation. For 70B models, you need 64GB+ RAM.
Is Apple Silicon (M1/M2/M3) good for AI?
Yes! Apple Silicon offers excellent AI performance with unified memory architecture. M1 Pro/Max, M2 Pro/Max, and M3 chips provide great performance for most local AI tasks. The unified memory allows efficient use of available RAM for AI models.
Can I upgrade my existing computer?
Often yes! The most impactful upgrades are usually RAM (if your motherboard supports more) and adding a GPU. However, very old CPUs (pre-2018) may become bottlenecks. Check your motherboard specifications for RAM and GPU compatibility.
