Hardware we track with 16–19 GB usable

Macs and unified-memory mini-PCs count about 75% of memory as usable (how we calculate).

Quick answers

What is the biggest LLM I can run with 16 GB of VRAM?
Ling-Coder-lite (16.8B parameters) is the biggest model we track that runs comfortably in 16 GB at Q4_K_M, needing about 12.7 GB with a ~4k context. At Q8 the biggest is HyperCLOVAX-SEED-Omni-8B.
How many models fit in 16 GB of VRAM?
388 of the 656 open models we track run fully in 16 GB at Q4 with room to spare, 340 also fit at Q8, and 5 more fit only with a short context.
Can I run a model that needs more than 16 GB?
Yes, with llama.cpp or Ollama you can offload some layers to system RAM, but speed drops sharply. For full-speed local inference the whole model plus its context cache should fit in GPU memory; we use 90% of 16 GB as the comfort line.
Which hardware has about 16 GB of usable memory?
The cheapest current device we track in this range is the Radeon RX 7600 XT (16 GB usable, $329 list price as of our last snapshot). 21 tracked devices have 16–19 GB usable.
