Quantizations:
- i_: English+Portuguese+Naval imatrix.
- _offloadX: X layers on the CENTER of model are quantized further and with quants fast on CPU. See below.
- _oldgpu: Also avoiding quants slow on old cards like GFX906 - MI50 (prefering Q4_0/Q4_1 quants).
- No i/offload/oldgpu: Standard llama.cpp quant with NO imatrix.
_offloadX: If the model won't fit in your GPU, you can offload some/all center experts to CPU using -ot. As those are quantized with Q2_K (and some Q3_K), they will be fast on CPU.
