DavidAU/gemma-3-12b-it-vl-Gemini-3-Pro-Preview-Heretic-Uncensored-Thinkinggemma-3-12b-it-vl-Gemini-3-Pro-Preview-Heretic-Uncensored-Thinking at I1-IQ1_S is exactly 2,947,416,512 bytes (2.74 GiB / 2.95 GB) — an effective 1.935 bits per weight, not the nominal 1. Its KV cache at 32K is 2.47 GiB, not the 12.00 GiB a flat formula predicts.

40 of 48 layers cache only a 1,024-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 I1-IQ1_S at roughly 6.38 GiB. The real file is 2.74 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 12.00 GiB at 32K context where the real figure is 2.47 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-3-12b-it-vl-Gemini-3-Pro-Preview-Heretic-Uncensored-Thinking need?
- I1-IQ1_S is exactly 2,947,416,512 bytes (2.74 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-3-12b-it-vl-Gemini-3-Pro-Preview-Heretic-Uncensored-Thinking's KV cache?
- 2.47 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-3-12b-it-vl-Gemini-3-Pro-Preview-Heretic-Uncensored-Thinking 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.
