How much VRAM does Mage-Flow need?

NVFP4 is exactly 2,373,295,968 bytes (2.21 GiB) in weights. Add the KV cache, which depends on context length, plus roughly half a gigabyte of runtime overhead.

Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts NVFP4 at roughly 2.16 GiB. The real file is 2.21 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.
