treadon/gemma4-E4B-it-abliterated

gemma4-E4B-it-abliterated at I1-IQ1_S is exactly 3,289,756,608 bytes (3.06 GiB / 3.29 GB) — an effective 3.314 bits per weight, not the nominal 1. Its KV cache at 32K is 0.51 GiB, not the 2.63 GiB a flat formula predicts.

35 of 42 layers cache only a 512-token window rather than the full context, on a period of . Figures assume the default configuration; --swa-full disables the saving entirely.

Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts I1-IQ1_S at roughly 4.16 GiB. The real file is 3.06 GiB, because a quantization is a mixture and some tensors are always kept at higher precision. The larger discrepancy is the cache: a flat formula gives 2.63 GiB at 32K context where the real figure is 0.51 GiB, because most of this model's layers cache a fixed window rather than the whole context.

Questions people ask

How much VRAM does gemma4-E4B-it-abliterated need?
I1-IQ1_S is exactly 3,289,756,608 bytes (3.06 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is gemma4-E4B-it-abliterated's KV cache?
0.51 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 gemma4-E4B-it-abliterated 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.
