16GB RAM
Best local LLMs for 16GB RAM
The cleanest starting points for local LLMs on 16GB machines: compact chat, coding and reasoning models that avoid painful memory pressure.
Quick answer
On 16GB RAM, the best experience usually comes from 4B-14B models in Q4_K_M or Q5_K_M. Bigger models can look tempting, but memory pressure quickly hurts latency.
