Running large language models locally on a Mac requires careful consideration of RAM usage, which is allocated to model weights, the context window (KV cache), and the operating system. Measurements indicate that the effective usable RAM for LLMs is approximately three-quarters of the total, with context size significantly impacting memory reservation, especially in older model architectures. Newer models like Qwen and Gemma show more efficient context caching, reducing memory overhead for longer documents. AI
IMPACT Understanding RAM requirements is crucial for users looking to run LLMs locally, impacting hardware purchasing decisions and model selection.
