Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 14.26 GiB. The real file is 15.50 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Architecture

Architecture unavailable — this repository is gated and no ungated mirror was found. Exact file sizes above are still authoritative; only the KV math needs the config.

Questions people ask

How much VRAM does shieldgemma-27b need?
Q4_K_M is exactly 16,645,382,784 bytes (15.50 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
Which quantization of shieldgemma-27b 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.
