TL;DR: Every public low-bit GGUF of this model is secretly ~4.70 bpw. Shim the rows to 256 and it becomes a real 3.07 bpw / 11.77 GiB file that runs 262K context on 16GB. Needs patched llama.cpp — not LM Studio or Ollama. In the AtomicChat HuggingFace repo it says "There is currently no good 16 GB…
