Ultrabooks struggle to run LLMs locally due to VRAM limits

Running large language models (LLMs) locally on ultrabooks with power-efficient processors like the Core i5-1345U presents significant hardware limitations, primarily due to the constrained VRAM available for the integrated GPU. While these laptops are designed for general productivity, attempting to use them for local LLM inference requires careful management of system resources, such as limiting context length and using heavily quantized models like Llama 3 8B in Q4 or Q5 formats. Even with these optimizations, performance is modest, with speeds around 2-4 tokens per second for an 8B model, making them suitable only for basic prompt testing or small model inference, not for demanding AI tasks.
