Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 4.47 GiB. The real file is 4.68 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask

How much VRAM does InternVL3_5-8B need?
Q4_K_M is exactly 5,027,780,512 bytes (4.68 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
Which quantization of InternVL3_5-8B 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.
