Safety classification models that run on 16 GB

4 models with published weights that fit in 16 GB — the common laptop. Counted at four-bit quantisation, weights only, leaving the machine about a third of its memory and a gigabyte for context: room for roughly 16 billion parameters. A mixture of experts is counted in full, because it is held in full even though only a few experts compute.

The commonest laptop configuration, and the point where a genuinely useful model runs locally: fourteen billion parameters at four-bit fits with room to spare for the context. Expect a capable general assistant that will not match the frontier, and remember that anything else the machine is doing competes for the same memory.

Models that classify content rather than produce it: what is unsafe, what breaks a policy, what should not be shown. They sit in front of or behind a bigger model, are small and cheap by design, and are the part of a system nobody notices until it is wrong. The thing to check is what the model was trained to catch, because policies differ and a guard tuned for one product's rules will be strict in the wrong places for yours.
