gemma-2-2b-it-abliterated
IlyaGusev/gemma-2-2b-it-abliteratedgemma-2-2b-it-abliterated at Q4_K_M is exactly 1,708,582,784 bytes (1.59 GiB / 1.71 GB) — an effective 5.228 bits per weight, not the nominal 4. Its KV cache at 32K is 1.85 GiB, not the 3.25 GiB a flat formula predicts.

13 of 26 layers cache only a 4,096-token window rather than the full context, on a period of 2. 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 1.37 GiB. The real file is 1.59 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 3.25 GiB at 32K context where the real figure is 1.85 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-2-2b-it-abliterated need?
- Q4_K_M is exactly 1,708,582,784 bytes (1.59 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-2-2b-it-abliterated's KV cache?
- 1.85 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-2-2b-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.
