Running large language models locally requires careful consideration of hardware, primarily GPU memory (VRAM). A general rule of thumb suggests approximately 0.6 GB of VRAM per billion parameters for 4-bit quantized models, but this does not account for the KV cache, which can add several gigabytes depending on context length and model architecture. For instance, a 32B model with a 32k context might need around 20 GB for weights and 8 GB for the cache, potentially exceeding a single 24 GB GPU. It is recommended to start with the smallest model that meets the task requirements, with models ranging from 8B for simple tasks to 70B+ for complex analysis, and to consider factors like power, cooling, and system RAM in addition to GPU capacity.
