gemma-3-1b-it-abliterated
huihui-ai/gemma-3-1b-it-abliteratedgemma-3-1b-it-abliterated at Q4_K_M is exactly 806,058,592 bytes (0.75 GiB / 0.81 GB) — an effective 6.449 bits per weight, not the nominal 4. Its KV cache at 32K is 0.15 GiB, not the 0.81 GiB a flat formula predicts.

22 of 26 layers cache only a 512-token window rather than the full context, on a period of 6. Figures assume the default configuration; --swa-full disables the saving entirely.

Will it run on your card?
Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 0.52 GiB. The real file is 0.75 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 0.81 GiB at 32K context where the real figure is 0.15 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 gemma-3-1b-it-abliterated need?
- Q4_K_M is exactly 806,058,592 bytes (0.75 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is gemma-3-1b-it-abliterated's KV cache?
- 0.15 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 gemma-3-1b-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.
