llm-surgery-dark-arts-gpt-oss-60b-96a12 at Q4_K_M is exactly 44,541,368,928 bytes (41.48 GiB / 44.54 GB) — an effective 5.847 bits per weight, not the nominal 4. Its KV cache at 32K is 0.77 GiB, not the 1.50 GiB a flat formula predicts.

12 of 24 layers cache only a 128-token window rather than the full context, on a period of . Figures assume the default configuration; --swa-full disables the saving entirely.

full quant x context sweep

Why other calculators give a different number

A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 31.93 GiB. The real file is 41.48 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 1.50 GiB at 32K context where the real figure is 0.77 GiB, because most of this model's layers cache a fixed window rather than the whole context.

Questions people ask

How much VRAM does llm-surgery-dark-arts-gpt-oss-60b-96a12 need?
Q4_K_M is exactly 44,541,368,928 bytes (41.48 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
How large is llm-surgery-dark-arts-gpt-oss-60b-96a12's KV cache?
0.77 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 llm-surgery-dark-arts-gpt-oss-60b-96a12 a mixture-of-experts model?
Yes — 96 experts, 12 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 llm-surgery-dark-arts-gpt-oss-60b-96a12 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.
