Mira-v1.12-Ties-27B
Lambent/Mira-v1.12-Ties-27BMira-v1.12-Ties-27B at I1-IQ1_S is exactly 6,264,014,176 bytes (5.83 GiB / 6.26 GB) — an effective 1.827 bits per weight, not the nominal 1. Its KV cache at 32K is 3.11 GiB, not the 15.50 GiB a flat formula predicts.

52 of 62 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 14.37 GiB. The real file is 5.83 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 15.50 GiB at 32K context where the real figure is 3.11 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 Mira-v1.12-Ties-27B need?
- I1-IQ1_S is exactly 6,264,014,176 bytes (5.83 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- How large is Mira-v1.12-Ties-27B's KV cache?
- 3.11 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 Mira-v1.12-Ties-27B 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.
