LOCAL LLM Compatibility Evaluation

This quick guide shows what types of large language models (LLMs) each of these laptops could support, based on their respective hardware specifications. It's meant to help you compare their suitability for running AI models locally.

LLM Category	Asus Vivobook S14 (M3407)	Lenovo Legion 5 Gen 10 (2025)
Small Models(1-3B):Examples: Phi-2, Qwen-1.8B	✔ Run smoothly.	✔ Run smoothly.
Medium Models(7-8B):Examples: Mistral-7B, Qwen-7B	✔ Good performance.	✔ Good performance.
Large Models(13-30B):Examples: Mixtral, Qwen-14B	✖ Not supported.	⚠ Can run using CPU + RAM fallback. Expect slower performance.
Extra-Large Models(65B+):Examples: LLaMA2-70B, Qwen1.5-72B	✖ Not supported on most systems. Requires high-end GPU or advanced setup.	⚠ Possible with CPU + RAM fallback using quantized models.
