How much VRAM does gemma-3-270m-qat need?

Q4_0 is exactly 241,409,024 bytes (0.22 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 Q4_0 at roughly 0.14 GiB. The real file is 0.22 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.
