thesilverheadengineer/llm-surgery-dark-arts-gpt-oss-60b-96a12llm-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.

Will it run on your card?
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.
Architecture
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.
