FAQ
How was this fit calculated?
Weights 8.43 GiB, KV cache 1.56 GiB at 8,192 tokens, engine overhead 0.50 GiB, then 5% headroom, for 11.0 GiB. Fast memory available is 18.0 GiB.
What if I change the quant or the context?
This page is Q4_K_M at 8,192 tokens. A smaller quant or a shorter context lowers the total. The homepage calculator changes both without a new page.
Can I trust the tokens per second?
The range 6–11 tok/s is a bandwidth roofline, 55% to 80% efficient. This dense model reads the whole weight file each token. Measure your own box before you buy around it.
