keithtyser/gemma-4-26B-A4B-it-local-abliterated-sota-internal-t34gemma-4-26B-A4B-it-local-abliterated-sota-internal-t34 at I1-IQ1_S is exactly 8,290,271,520 bytes (7.72 GiB / 8.29 GB) — an effective 2.570 bits per weight, not the nominal 1. Its KV cache at 32K is 1.54 GiB, not the 7.50 GiB a flat formula predicts.

25 of 30 layers cache only a 1,024-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 13.52 GiB. The real file is 7.72 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 7.50 GiB at 32K context where the real figure is 1.54 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-4-26B-A4B-it-local-abliterated-sota-internal-t34 need?
- I1-IQ1_S is exactly 8,290,271,520 bytes (7.72 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-4-26B-A4B-it-local-abliterated-sota-internal-t34's KV cache?
- 1.54 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.
- Is gemma-4-26B-A4B-it-local-abliterated-sota-internal-t34 a mixture-of-experts model?
- Yes — 128 experts, null routed per token. Every expert must be resident, but only the routed ones are read per token, which is why its memory requirement and its speed behave very differently.
- Which quantization of gemma-4-26B-A4B-it-local-abliterated-sota-internal-t34 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.
