Huihui-gemma-3n-E4B-it-abliterated
huihui-ai/Huihui-gemma-3n-E4B-it-abliteratedHuihui-gemma-3n-E4B-it-abliterated at Q4_K_M is exactly 4,237,064,192 bytes (3.95 GiB / 4.24 GB) — an effective 4.318 bits per weight, not the nominal 4. Its KV cache at 32K is 0.49 GiB, not the 2.19 GiB a flat formula predicts.

Will it run on your card?
Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 4.11 GiB. The real file is 3.95 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 2.19 GiB at 32K context where the real figure is 0.49 GiB, because most of this model's layers cache a fixed window rather than the whole context.
Architecture
Questions people ask
- How much VRAM does Huihui-gemma-3n-E4B-it-abliterated need?
- Q4_K_M is exactly 4,237,064,192 bytes (3.95 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is Huihui-gemma-3n-E4B-it-abliterated's KV cache?
- 0.49 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 Huihui-gemma-3n-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.
