This article explores the feasibility of running Large Language Models (LLMs) locally using only a CPU, challenging the assumption that expensive GPUs are strictly necessary. By testing eight different models on an older Intel i5 laptop with 12GB of RAM via Ollama, the author identifies which models offer practical usability for everyday tasks.
Key points include:
- Using tokens per second as a more critical metric for usability than model size or RAM usage alone.
- Why 1B to 2B parameter models provide the best balance of responsiveness and reasoning on low-end hardware.
- The effectiveness of GGUF quantization (specifically Q4_K_M) in reducing resource demands.
- A comparison of various model tiers, from ultra-fast tiny models like Qwen 0.6B to slower, high-capability models like Ministral 3 8B.
