Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 7.74 GiB. The real file is 8.38 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask

How much VRAM does NousCoder-14B need?
Q4_K_M is exactly 9,001,754,752 bytes (8.38 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is NousCoder-14B's KV cache?
5.00 GiB at 32K context with an f16 cache, computed per layer. Quantizing the cache to q8_0 roughly halves it, which is often the difference between a context length fitting and not.
Which quantization of NousCoder-14B should I use?
Q4_K_M is the usual default. Pick the largest quantization that fits your card at the context you actually need — the table above gives exact sizes for every one published.
