Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 18.94 GiB. The real file is 20.27 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask

How much VRAM does Hermes-4.3-36B-heretic need?
Q4_K_M is exactly 21,762,146,464 bytes (20.27 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is Hermes-4.3-36B-heretic's KV cache?
8.00 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 Hermes-4.3-36B-heretic 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.
